Artist's illustration of a cyborg

A cyborg (/ˈsbɔːrɡ/, a portmanteau of cybernetic and organism) is a being with both organic and biomechatronic body parts. The term was coined in 1960 by Manfred Clynes and Nathan S. Kline.[1] In contrast to biorobots and androids, the term cyborg applies to a living organism that has restored function or enhanced abilities due to the integration of some artificial component or technology that relies on feedback.[2]

Description and definition

[edit]

Alternative names for a cyborg include cybernetic organism, cyber-organism, cyber-organic being, cybernetically enhanced organism, cybernetically augmented organism, technorganic being, techno-organic being, and techno-organism.

Unlike bionics, biorobotics, or androids, a cyborg is an organism that has restored function or, especially, enhanced abilities due to the integration of some artificial component or technology that relies on some sort of feedback, for example: prostheses, artificial organs, implants or, in some cases, wearable technology.[3] Cyborg technologies may enable or support collective intelligence.[4] A related idea is the "augmented human".[3][5][6] While cyborgs are commonly thought of as mammals, including humans, the term can apply to any organism.

Placement and distinctions

[edit]

D. S. Halacy's Cyborg: Evolution of the Superman (1965) featured an introduction which spoke of a "new frontier" that was "not merely space, but more profoundly the relationship between 'inner space' to 'outer space' – a bridge...between mind and matter."[7]

In "A Cyborg Manifesto", Donna Haraway rejects the notion of rigid boundaries between humanity and technology, arguing that, as humans depend on more technology over time, humanity and technology have become too interwoven to draw lines between them. She believes that since we have allowed and created machines and technology to be so advanced, there should be no reason to fear what we have created, and cyborgs should be embraced because they are part of human identities.[8] However, Haraway has also expressed concern over the contradictions of scientific objectivity and the ethics of technological evolution, and has argued that "There are political consequences to scientific accounts of the world."[9]

Biosocial definition

[edit]

According to some definitions of the term, the physical attachments that humans have with even the most basic technologies have already made them cyborgs.[10] In a typical example, a human with an artificial cardiac pacemaker or implantable cardioverter-defibrillator would be considered a cyborg, since these devices measure voltage potentials in the body, perform signal processing, and can deliver electrical stimuli, using a synthetic feedback mechanism to keep that person alive. Implants, especially cochlear implants, that combine mechanical modification with any kind of feedback response are also cybernetic enhancements. Some theorists[who?] cite such modifications as contact lenses, hearing aids, smartphones,[11] or intraocular lenses as examples of fitting humans with technology to enhance their biological capabilities.

The emerging trend of implanting microchips inside the body (mainly the hands), to make financial operations like a contactless payment, or basic tasks like opening a door, has been erroneously marketed as more recent examples of cybernetic enhancement. The latter has not yet seen significant traction outside niche areas in Scandinavia and in actual function is little more than a pre-programmed Radio-frequency identification (RFID) microchip encased in glass that does not interact with the human body (it is the same technology used in the microchips injected into animals for ease of identification), thus not fitting the definition of a cybernetic implant.

As cyborgs currently are on the rise, some theorists[who?] argue there is a need to develop new definitions of aging. For instance, a bio-techno-social definition of aging has been suggested.[12]

The term is also used to address human-technology mixtures in the abstract. This includes not only commonly used pieces of technology such as phones, computers, the Internet, and so on, but also artifacts that are not usually considered technology; for example, pen and paper, and speech and language. When augmented with these technologies and connected in communication with people in other times and places, a person becomes capable of more than they were before. An example is a computer, which gains power by using Internet protocols to connect with other computers. Another example is a social-media bot—either a bot-assisted human or a human-assisted-bot—used to target social media with likes and shares.[13] Cybernetic technologies thus include highways, pipes, electrical wiring, buildings, electrical plants, libraries, and other infrastructural constructs.

Bruce Sterling, in his Shaper/Mechanist universe, suggested an idea of an alternative cyborg called 'Lobster', which is made not by using internal implants, but by using an external shell (e.g. a powered exoskeleton).[14] The computer game Deus Ex: Invisible War prominently features cyborgs called Omar, Russian for 'lobster'.[citation needed]

Evolutionary perspective

[edit]

In 1994, Hans Hass formulated a scientific view of the human-machine hybrids he called "hypercells".[15] They can expand their biological cell body with artificial artifacts and thus expand their performance body. The theory of hypercells or "Homo proteus", as Hass called the human-machine hybrid to distinguish Homo sapiens, extends Charles Darwin's theory of evolution and deals with the course of evolution beyond humans.

In his 2019 book Novacene, James Lovelock used the term "cyborgs" to refer to the next generation of beings who will become the "understanders of the future" and "lead the cosmos to self-knowledge". While acknowledging the organic component in Clynes' and Kline's definition, he proposed that these cyborgs "will have designed and built themselves from the artificial intelligence systems we have already constructed", and used the term cyborg "to emphasize that the new intelligent beings will have arisen, like us, from Darwinian evolution."[16]

Origins

[edit]

The concept of a man-machine mixture was widespread in science fiction before World War II. As early as 1843, Edgar Allan Poe described a man with extensive prostheses in the short story "The Man That Was Used Up". In 1911, Jean de La Hire introduced the Nyctalope, a science fiction hero who was perhaps the first literary cyborg, in Le Mystère des XV (later translated as The Nyctalope on Mars).[17][18][19] Nearly two decades later, Edmond Hamilton presented space explorers with a mixture of organic and machine parts in his 1928 novel The Comet Doom. He later featured the talking, living brain of an old scientist, Simon Wright, floating in a transparent case, and in all the adventures of his famous hero, Captain Future. In 1944, in the short story "No Woman Born", C. L. Moore wrote of Deirdre, a dancer, whose body was burned completely and whose brain was placed in a faceless but beautiful and supple mechanical body.

In 1960, the term "cyborg" was coined by Manfred E. Clynes and Nathan S. Kline to refer to their conception of an enhanced human being who could survive in extraterrestrial environments:[1]

For the exogenously extended organizational complex functioning as an integrated homeostatic system unconsciously, we propose the term 'Cyborg'.

Their concept was the outcome of thinking about the need for an intimate relationship between human and machine as the new frontier of space exploration was beginning to develop. A designer of physiological instrumentation and electronic data-processing systems, Clynes was the chief research scientist in the Dynamic Simulation Laboratory at Rockland State Hospital in New York.

The term first appears in print 5 months earlier when The New York Times reported on the "Psychophysiological Aspects of Space Flight Symposium" where Clynes and Kline first presented their paper:

A cyborg is essentially a man-machine system in which the control mechanisms of the human portion are modified externally by drugs or regulatory devices so that the being can live in an environment different from the normal one.[20]

Thereafter, Hamilton would first use the term "cyborg" explicitly in the 1962 short story, "After a Judgment Day", to describe the "mechanical analogs" called "Charlies," explaining that "[c]yborgs, they had been called from the first one in the 1960s...cybernetic organisms."

In 2001, a book titled Cyborg: Digital Destiny and Human Possibility in the Age of the Wearable computer was published by Doubleday.[21] Some of the ideas in the book were incorporated into the documentary film Cyberman that same year.

Cyborg tissues in engineering

[edit]

Cyborg tissues structured with carbon nanotubes and plant or fungal cells have been used in artificial tissue engineering to produce new materials for mechanical and electrical uses.

Such work was presented by Raffaele Di Giacomo, Bruno Maresca, and others, at the Materials Research Society's spring conference on 3 April 2013.[22] The cyborg obtained was inexpensive, light and had unique mechanical properties. It could also be shaped in the desired forms. Cells combined with multi-walled carbon nanotubes (MWCNTs) co-precipitated as a specific aggregate of cells and nanotubes that formed a viscous material. Likewise, dried cells still acted as a stable matrix for the MWCNT network. When observed by optical microscopy, the material resembled an artificial "tissue" composed of highly packed cells. The effect of cell drying was manifested by their "ghost cell" appearance. A rather specific physical interaction between MWCNTs and cells was observed by electron microscopy, suggesting that the cell wall (the outermost part of fungal and plant cells) may play a major active role in establishing a carbon nanotube's network and its stabilization. This novel material can be used in a wide range of electronic applications, from heating to sensing. For instance, using Candida albicans cells, a species of yeast that often lives inside the human gastrointestinal tract, cyborg tissue materials with temperature sensing properties have been reported.[23]

Actual cyborgization attempts

[edit]

In current prosthetic applications, the C-Leg system developed by Otto Bock HealthCare, is used to replace a human leg that has been amputated because of injury or illness. The use of sensors in the artificial C-Leg aids in walking significantly by attempting to replicate the user's natural gait, as it would be prior to amputation.[24] A similar system is being developed by the Swedish orthopedic company Integrum, the OPRA Implant System, which is surgically anchored and integrated by means of osseointegration into the skeleton of the remainder of the amputated limb.[25] The same company has developed e-OPRA, a will-powered upper limb prosthesis system that is being evaluated in a clinical trial to allow sensory input to the central nervous system using pressure and temperature sensors in the prosthesis' finger tips.[26][27] Prostheses like the C-Leg, the e-OPRA Implant System, and the iLimb, are considered by some to be the first real steps towards the next generation of real-world cyborg applications.[citation needed] Additionally, cochlear implants and magnetic implants, which provide people with a sense that they would not otherwise have had, can additionally be thought of as creating cyborgs.[citation needed]

In vision science, direct brain implants have been used to treat non-congenital (acquired) blindness. One of the first scientists to come up with a working brain interface to restore sight was private researcher William Dobelle. Dobelle's first prototype was implanted into "Jerry", a man blinded in adulthood, in 1978. A single-array BCI containing 68 electrodes was implanted onto Jerry's visual cortex and succeeded in producing phosphenes, the sensation of seeing light. The system included cameras mounted on glasses to send signals to the implant. Initially, the implant allowed Jerry to see shades of grey in a limited field of vision at a low frame-rate. This also required him to be hooked up to a two-ton mainframe, but shrinking electronics and faster computers made his artificial eye more portable and now enable him to perform simple tasks unassisted.[28]

In 1997, Philip Kennedy, a scientist and physician, created the world's first human cyborg from Johnny Ray, a Vietnam War veteran who suffered a stroke. Ray's body, as doctors called it, was "locked in". Ray wanted his old life back so he agreed to Kennedy's experiment. Kennedy embedded an implant he designed (and named a "neurotrophic electrode") near the injured part of Ray's brain so that Ray would be able to have some movement back in his body. The surgery went successfully, but in 2002, Ray died.[29]

In 2002, Canadian Jens Naumann, also blinded in adulthood, became the first in a series of 16 paying patients to receive Dobelle's second-generation implant, marking one of the earliest commercial uses of BCIs. The second-generation device used a more sophisticated implant enabling better mapping of phosphenes into coherent vision. Phosphenes are spread out across the visual field in what researchers call the starry-night effect. Immediately after his implant, Naumann was able to use his imperfectly restored vision to drive slowly around the parking area of the research institute.[30]

In contrast to replacement technologies, in 2002, under the heading Project Cyborg, a British scientist, Kevin Warwick, had an array of 100 electrodes fired into his nervous system to link his nervous system into the internet to investigate enhancement possibilities. With this in place, Warwick successfully carried out a series of experiments including extending his nervous system over the internet to control a robotic hand, also receiving feedback from the fingertips to control the hand's grip. This was a form of extended sensory input. Subsequently, he investigated ultrasonic input to remotely detect the distance to objects. Finally, with electrodes also implanted into his wife's nervous system, they conducted the first direct electronic communication experiment between the nervous systems of two humans.[31][32]

Since 2004, British artist Neil Harbisson has had a cyborg antenna implanted in his head that allows him to extend his perception of colors beyond the human visual spectrum through vibrations in his skull.[33] His antenna was included within his 2004 passport photograph which has been said to confirm his cyborg status.[34] In 2012 at TEDGlobal,[35] Harbisson explained that he started to feel like a cyborg when he noticed that the software and his brain had united and given him an extra sense.[35] Harbisson is a co-founder of the Cyborg Foundation (2004)[36] and cofounded the Transpecies Society in 2017, which is an association that empowers individuals with non-human identities and supports them in their decisions to develop unique senses and new organs.[37] Neil Harbisson is a global advocate for the rights of cyborgs.

Rob Spence, a Toronto-based filmmaker, who titles himself a real-life "Eyeborg", severely damaged his right eye in a shooting accident on his grandfather's farm as a child.[38] Many years later, in 2005, he decided to have his ever-deteriorating and now technically blind eye surgically removed,[39] whereafter he wore an eyepatch for some time before he later, after having played for some time with the idea of installing a camera instead, contacted professor Steve Mann at the Massachusetts Institute of Technology, an expert in wearable computing and cyborg technology.[39]

Under Mann's guidance, Spence, at age 36, created a prototype in the form of the miniature camera which could be fitted inside his prosthetic eye; an invention that would come to be named by Time magazine as one of the best inventions of 2009. The bionic eye records everything he sees and contains a 1.5 mm2, low-resolution video camera, a small round printed circuit board, a wireless video transmitter, which allows him to transmit what he is seeing in real-time to a computer, and a 3-volt rechargeable VARTA microbattery. The eye is not connected to his brain and has not restored his sense of vision. Additionally, Spence has also installed a laser-like LED light in one version of the prototype.[40]

Furthermore, many people with multifunctional radio frequency identification (RFID) microchips injected into a hand are known to exist. With the chips they are able to swipe cards, open or unlock doors, operate devices such as printers or, with some using cryptocurrency, buy products, such as drinks, with a wave of the hand.[41][42][43][44][45]

bodyNET

[edit]

bodyNET is an application of human-electronic interaction currently[when?] in development by researchers from Stanford University.[46] The technology is based on stretchable semiconductor materials (Elastronic). According to their article in Nature, the technology is composed of smart devices, screens, and a network of sensors that can be implanted into the body, woven into the skin or worn as clothes. It has been suggested that this platform can potentially replace the smartphone in the future.[47]

Practical applications

[edit]

In medicine and biotechnology

[edit]

In medicine, there are two important and different types of cyborgs: the restorative and the enhanced. Restorative technologies "restore lost function, organs, and limbs."[48] The key aspect of restorative cyborgization is the repair of broken or missing processes to revert to a healthy or average level of function. There is no enhancement to the original faculties and processes that were lost.

On the contrary, the enhanced cyborg "follows a principle, and it is the principle of optimal performance: maximising output (the information or modifications obtained) and minimising input (the energy expended in the process)".[49] Thus, the enhanced cyborg intends to exceed normal processes or even gain new functions that were not originally present.

Prosthetics

[edit]

Although prostheses in general supplement lost or damaged body parts with the integration of a mechanical artifice, bionic implants in medicine allow model organs or body parts to mimic the original function more closely. Michael Chorost wrote a memoir of his experience with cochlear implants, or bionic ears, titled Rebuilt: How Becoming Part Computer Made Me More Human.[50] Jesse Sullivan became one of the first people to operate a fully robotic limb through a nerve-muscle graft, enabling him a complex range of motions beyond that of previous prosthetics.[51] By 2004, a fully functioning artificial heart was developed.[52] The continued technological development of bionic and (bio-)nanotechnologies begins to raise the question of enhancement, and of the future possibilities for cyborgs which surpass the original functionality of the biological model. The ethics and desirability of "enhancement prosthetics" have been debated; their proponents include the transhumanist movement, with its belief that new technologies can assist the human race in developing beyond its present, normative limitations such as aging and disease, as well as other, more general inabilities, such as limitations on speed, strength, endurance, and intelligence. Opponents of the concept describe what they believe to be biases which propel the development and acceptance of such technologies; namely, a bias towards functionality and efficiency that may compel assent to a view of human people which de-emphasizes as defining characteristics actual manifestations of humanity and personhood, in favor of definition in terms of upgrades, versions, and utility.[53][54]

Retinal implants are another form of cyborgization in medicine. The theory behind retinal stimulation to restore vision for those suffering from retinitis pigmentosa and vision loss due to aging (conditions in which people have an abnormally low number of retinal ganglion cells), is that the retinal implant and electrical stimulation would act as a substitute for the missing ganglion cells (cells which connect the eye to the brain).

While the work to perfect this technology is still being done, there have already been major advances in the use of electronic stimulation of the retina to allow the eye to sense patterns of light. A specialized camera is worn by the subject, such as on the frames of their glasses, which converts the image into a pattern of electrical stimulation. A chip located in the user's eye would then electrically stimulate the retina with this pattern by exciting certain nerve endings which transmit the image to the optic centers of the brain, and the image would then appear to the user. If technological advances proceed as planned, this technology may be used by thousands of blind people and restore vision to most of them.

A similar process has been created to aid people who have lost their vocal cords. This experimental device would do away with previously used robotic-sounding voice simulators. The transmission of sound would start with a surgery to redirect the nerve that controls the voice and sound production to a muscle in the neck, where a nearby sensor would be able to pick up its electrical signals. The signals would then move to a processor which would control the timing and pitch of a voice simulator. That simulator would then vibrate producing a multi-tonal sound that could be shaped into words by the mouth.[55]

An article published in Nature Materials in 2012 reported research on "cyborg tissues" (engineered human tissues with embedded three-dimensional mesh of nanoscale wires), with possible medical implications.[56]

In 2014, researchers from the University of Illinois at Urbana–Champaign and Washington University in St. Louis had developed a device that could keep a heart beating endlessly. By using 3D printing and computer modeling, these scientists developed an electronic membrane that could successfully replace pacemakers. The device uses a "spider-web like network of sensors and electrodes" to monitor and maintain a normal heart rate with electrical stimuli. Unlike traditional pacemakers that are similar from patient to patient, the elastic heart glove is made custom by using high-resolution imaging technology. The first prototype was created to fit a rabbit's heart, operating the organ in an oxygen and nutrient-rich solution. The stretchable material and circuits of the apparatus were first constructed by Professor John A. Rogers in which the electrodes are arranged in an s-shape design to allow them to expand and bend without breaking. Although the device is only currently used as a research tool to study changes in heart rate, in the future the membrane may serve as a safeguard against heart attacks.[57]

Neural enhancement and restoration

[edit]

A brain–computer interface, or BCI, provides a direct path of communication from the brain to an external device, effectively creating a cyborg. Research into invasive BCIs, which use electrodes implanted directly into the grey matter of the brain, has focused on restoring damaged eyesight in the blind and providing functionality to paralyzed people, most notably those with severe cases, such as locked-in syndrome. This technology could enable people who are missing a limb or are in a wheelchair the power to control the devices that aid them through neural signals sent from the brain implants directly to computers or the devices. It is possible that this technology will also eventually be used with healthy people.[58]

Deep brain stimulation is a neurological surgical procedure used for therapeutic purposes. This process has aided in treating patients diagnosed with Parkinson's disease, Alzheimer's disease, Tourette syndrome, epilepsy, chronic headaches, and mental disorders. After the patient is unconscious, through anesthesia, brain pacemakers or electrodes, are implanted into the region of the brain where the cause of the disease is present. The region of the brain is then stimulated by bursts of electric current to disrupt the oncoming surge of seizures. Like all invasive procedures, deep brain stimulation may put the patient at a higher risk. However, there have been more improvements in recent years with deep brain stimulation than any available drug treatment.[59]

Pharmacology

[edit]

Automated insulin delivery systems, colloquially also known as the "artificial pancreas", are a substitute for the lack of natural insulin production by the body, most notably in Type 1 Diabetes. Currently available systems combine a continuous glucose monitor with an insulin pump that can be remote controlled, forming a control loop that automatically adjusts the insulin dosage depending on the current blood glucose level. Examples of commercial systems that implement such a control loop are the MiniMed 670G from Medtronic[60] and the t:slim x2 from Tandem Diabetes Care.[61] Do-it-yourself artificial pancreas technologies also exist, though these are not verified or approved by any regulatory agency.[62] Upcoming next-generation artificial pancreas technologies include automatic glucagon infusion in addition to insulin, to help prevent hypoglycemia and improve efficiency. One example of such a bi-hormonal system is the Beta Bionics iLet.[63]

In the military

[edit]

Military organizations' research has recently focused on the use of cyborg animals for the purposes of a supposed tactical advantage. DARPA has announced its interest in developing "cyborg insects" to transmit data from sensors implanted into the insect during the pupa stage. The insect's motion would be controlled from a microelectromechanical system (MEMS) and could conceivably survey an environment or detect explosives and gas.[64] Similarly, DARPA is developing a neural implant to remotely control the movement of sharks. The shark's unique senses would then be exploited to provide data feedback in relation to enemy ship movement or underwater explosives.[65]

In 2006, researchers at Cornell University invented[66] a new surgical procedure to implant artificial structures into insects during their metamorphic development.[67][68] The first insect cyborgs, moths with integrated electronics in their thorax, were demonstrated by the same researchers.[69][70] The initial success of the techniques has resulted in increased research and the creation of a program called Hybrid-Insect-MEMS (HI-MEMS). Its goal, according to DARPA's Microsystems Technology Office, is to develop "tightly coupled machine-insect interfaces by placing micro-mechanical systems inside the insects during the early stages of metamorphosis."[71]

The use of neural implants has recently been attempted, with success, on cockroaches. Surgically applied electrodes were put on the insect, which was remotely controlled by a human. The results, although sometimes different, basically showed that the cockroach could be controlled by the impulses it received through the electrodes. DARPA is now funding this research because of its obvious beneficial applications to the military and other areas[72]

In 2009 at the Institute of Electrical and Electronics Engineers (IEEE) MEMS conference in Italy, researchers demonstrated the first "wireless" flying-beetle cyborg.[73] Engineers at the University of California, Berkeley, have pioneered the design of a "remote-controlled beetle", funded by the DARPA HI-MEMS Program.[74] This was followed later that year by the demonstration of wireless control of a "lift-assisted" moth-cyborg.[75]

Eventually researchers plan to develop HI-MEMS for dragonflies, bees, rats, and pigeons.[76][77] For the HI-MEMS cybernetic bug to be considered a success, it must fly 100 metres (330 ft) from a starting point, guided via computer into a controlled landing within 5 metres (16 ft) of a specific end point. Once landed, the cybernetic bug must remain in place.[76]

In 2020, an article published in Science Robotics[78] by researchers at the University of Washington reported a mechanically steerable wireless camera attached to beetles.[79] Miniature cameras weighing 248 mg were attached to live beetles of the Tenebrionid genera Asbolus and Eleodes. The camera wirelessly streamed video to a smartphone via Bluetooth for up to 6 hours and the user could remotely steer the camera to achieve a bug's-eye view.[80]

In sports

[edit]

In 2016, Cybathlon became the first cyborg 'Olympics'; celebrated in Zurich, Switzerland, it was the first worldwide and official celebration of cyborg sports. In this event, 16 teams of people with disabilities used technological developments to turn themselves into cyborg athletes. There were 6 different events and its competitors used and controlled advanced technologies such as powered prosthetic legs and arms, robotic exoskeletons, bikes, and motorized wheelchairs.[81]

This was already a remarkable improvement, as it allowed disabled people to compete and showed the several technological enhancements that are already making a difference; however, it showed that there is still a long way to go. For instance, the exoskeleton race still required its participants to stand up from a chair and sit down, navigate a slalom and other simple activities such as walking over stepping stones and climbing up and down stairs. Despite the simplicity of these activities, 8 of the 16 teams that participated in the event drop off before the start.[82]

Nonetheless, one of the main goals of this event and such simple activities is to show how technological enhancements and advanced prosthetics can make a difference in people's lives. The next Cybathlon that was expected to occur in 2020, was cancelled due to the coronavirus pandemic.

In art

[edit]

The concept of the cyborg is often associated with science fiction. However, many artists have incorporated and reappropriated the idea of cybernetic organisms into their work, using disparate aesthetics and often realising actual cyborg constructs; their works range from performances, to paintings and installations. Some of the pioneering artists who created such works are H. R. Giger, Stelarc, Orlan, Shu Lea Cheang, Lee Bul, Tim Hawkinson, Steve Mann, Patricia Piccinini. More recently, this type of artistic practice has been expanded upon by artists such as Marco Donnarumma, Wafaa Bilal, Neil Harbisson, Moon Ribas, Manel De Aguas and Quimera Rosa.

Stelarc is a performance artist who has visually probed and acoustically amplified his body. He uses medical instruments, prosthetics, robotics, virtual reality systems, the Internet and biotechnology to explore alternate, intimate and involuntary interfaces with the body. He has made three films of the inside of his body and has performed with a third hand and a virtual arm. Between 1976 and 1988 he completed 25 body suspension performances with hooks into the skin. For 'Third Ear', he surgically constructed an extra ear within his arm that was internet-enabled, making it a publicly accessible acoustical organ for people in other places.[83] He is presently performing as his avatar from his second life site.[84]

Tim Hawkinson promotes the idea that bodies and machines are coming together as one, where human features are combined with technology to create the Cyborg. Hawkinson's piece Emoter presented how society is now dependent on technology.[85]

Marco Donnarumma is a performance artist and new media artist. In his work the body becomes a morphing language to speak critically of ritual, power and technology. For his "7 Configurations" cycle, between 2014 and 2019, he engineered and created six AI prostheses, each embodying an uncanny configuration of the machinic with the organic.[86] The prostheses – designed together with a team of artists and scientists – are useless prostheses, paradoxical objects designed for the body, but not to enhance it, rather to subtract functions from it: a skin-cutting robot with a steel metal knife, a facial prosthesis which blocks the wearer's gaze with a mechanical arm, and two robotic spines that function as additional limbs without a body. The prostheses have been created to act as performers with their own agency, that is, to interact with their human partners without being controlled externally. The machines are embedded with biomimetic neural networks, information processing algorithms inspired by the biological nervous system of mammals. Developed by Donnarumma in collaboration with the Neurorobotics Research Laboratory (DE), these neural networks endow the machines with artificial cognitive and sensorimotor skills.[87]

Wafaa Bilal is an Iraqi-American performance artist who had a small 10-megapixel digital camera surgically implanted into the back of his head, part of a project entitled 3rd I.[88] For one year, beginning 15 December 2010, an image was captured once per minute 24 hours a day and streamed live to www.3rdi.me and the Mathaf: Arab Museum of Modern Art. The site also displays Bilal's location via GPS. Bilal says that the reason why he put the camera in the back of the head was to make an "allegorical statement about the things we don't see and leave behind."[89] As a professor at NYU, this project raised privacy issues, and so Bilal was asked to ensure that his camera did not take photographs in NYU buildings.[89]

Machines are becoming more ubiquitous in the artistic process itself, with computerized drawing pads replacing pen and paper, and drum machines becoming nearly as popular as human drummers. Composers such as Brian Eno have developed and used software that can build entire musical scores from a few basic mathematical parameters.[90]

Scott Draves is a generative artist whose work is explicitly described as a "cyborg mind". His Electric Sheep project generates abstract art by combining the work of many computers and people over the internet.[91]

Artists as cyborgs

[edit]

Artists have explored the term cyborg from a perspective involving imagination. Some work to make an abstract idea of technological and human-bodily union apparent to reality in an art form using varying mediums, from sculptures and drawings to digital renderings. Artists who seek to make cyborg-based fantasies a reality often call themselves cyborg artists, or may consider their artwork "cyborg". How an artist or their work may be considered cyborg will vary depending upon the interpreter's flexibility with the term.

Scholars that rely upon a strict, technical description of a cyborg, often going by Norbert Wiener's cybernetic theory and Manfred E. Clynes and Nathan S. Kline's first use of the term, would likely argue that most cyborg artists do not qualify to be considered cyborgs.[92] Scholars considering a more flexible description of cyborgs may argue it incorporates more than cybernetics.[93] Others may speak of defining subcategories, or specialized cyborg types, that qualify different levels of cyborg at which technology influences an individual. This may range from technological instruments being external, temporary, and removable to being fully integrated and permanent.[94] Nonetheless, cyborg artists are artists. Being so, it can be expected for them to incorporate the cyborg idea rather than a strict, technical representation of the term,[95] seeing how their work will sometimes revolve around other purposes outside of cyborgism.[92]

In body modification

[edit]

As medical technology becomes more advanced, some techniques and innovations are adopted by the body modification community. While not yet cyborgs in the strict definition of Manfred Clynes and Nathan Kline, technological developments like implantable silicon silk electronics,[96] augmented reality[97] and QR codes[98] are bridging the disconnect between technology and the body. Hypothetical technologies such as digital tattoo interfaces[99][100] would blend body modification aesthetics with interactivity and functionality, bringing a transhumanist way of life into present day reality.

In addition, it is quite plausible for anxiety expression to manifest. Individuals may experience pre-implantation feelings of fear and nervousness. To this end, individuals may also embody feelings of uneasiness, particularly in a socialized setting, due to their post-operative, technologically augmented bodies, and mutual unfamiliarity with the mechanical insertion. Anxieties may be linked to notions of otherness or a cyborged identity.[101]

In space

[edit]

Sending humans to space is a dangerous task in which the implementation of various cyborg technologies could be used in the future for risk mitigation.[102] Stephen Hawking, a renowned physicist, stated "Life on Earth is at the ever-increasing risk of being wiped out by a disaster such as sudden global warming, nuclear war ... I think the human race has no future if it doesn't go into space." The difficulties associated with space travel could mean it might be centuries before humans ever become a multi-planet species.[citation needed] There are many effects of spaceflight on the human body. One major issue of space exploration is the biological need for oxygen. If this necessity was taken out of the equation, space exploration would be revolutionized. A theory proposed by Manfred E. Clynes and Nathan S. Kline is aimed at tackling this problem. The two scientists theorized that the use of an inverse fuel cell that is "capable of reducing CO2 to its components with the removal of the carbon and re-circulation of the oxygen ..."[103] could make breathing unnecessary. Another prominent issue is radiation exposure. Yearly, the average human on earth is exposed to approximately 0.30 rem of radiation, while an astronaut aboard the International Space Station for 90 days is exposed to 9 rem.[104] To tackle the issue, Clynes and Kline theorized a cyborg containing a sensor that would detect radiation levels and a Rose osmotic pump "which would automatically inject protective pharmaceuticals in appropriate doses." Experiments injecting these protective pharmaceuticals into monkeys have shown positive results in increasing radiation resistance.[103]

Although the effects of spaceflight on our bodies are an important issue, the advancement of propulsion technology is just as important. With our current technology, it would take us about 260 days to get to Mars.[105] A study backed by NASA proposes an interesting way to tackle this issue through deep sleep, or torpor. With this technique, it would "reduce astronauts' metabolic functions with existing medical procedures."[106] So far experiments have only resulted in patients being in torpor state for one week. Advancements to allow for longer states of deep sleep would lower the cost of the trip to Mars as a result of reduced astronaut resource consumption.

In cognitive science

[edit]

Theorists such as Andy Clark suggest that interactions between humans and technology result in the creation of a cyborg system. In this model, cyborg is defined as a part-biological, part-mechanical system that results in the augmentation of the biological component and the creation of a more complex whole. Clark argues that this broadened definition is necessary to an understanding of human cognition. He suggests that any tool which is used to offload part of a cognitive process may be considered the mechanical component of a cyborg system. Examples of this human and technology cyborg system can be very low tech and simplistic, such as using a calculator to perform basic mathematical operations or pen and paper to make notes, or as high tech as using a personal computer or phone. According to Clark, these interactions between a person and a form of technology integrate that technology into the cognitive process in a way that is analogous to the way that a technology that would fit the traditional concept of cyborg augmentation becomes integrated with its biological host. Because all humans in some way use technology to augment their cognitive processes, Clark comes to the conclusion that we are "natural-born cyborgs."[107] Professor Donna Haraway also theorizes that people, metaphorically or literally, have been cyborgs since the late twentieth century. If one considers the mind and body as one, much of humanity is aided with technology in almost every way, which hybridizes humans with technology.[108]

Future scope and regulation of implantable technologies

[edit]

Given the technical scope of current and future implantable sensory/telemetric devices, such devices will be greatly proliferated, and will have connections to commercial, medical, and governmental networks. For example, in the medical sector, patients will be able to log in to their home computer, and thus visit virtual doctor's offices, medical databases, and receive medical prognoses from the comfort of their own home from the data collected through their implanted telemetric devices.[109] However, this online network presents large security concerns because it has been proven by several U.S. universities that hackers could get onto these networks and shut down peoples' electronic prosthetics.[109] Cyborg data mining refers to the collection of data produced by implantable devices.

These sorts of technologies are already present in the U.S. workforce as a firm in River Falls, Wisconsin, called Three Square Market partnered with a Swedish firm Biohacks Technology to implant RFID microchips (which are about the size of a grain of rice) in the hands of its employees that allow employees to access offices, computers, and even vending machines. More than 50 of the firm's 85 employees were chipped. It was confirmed that the American Food and Drug Administration approved of these implantations.[110] If these devices are to be proliferated within society, then the question that begs to be answered is what regulatory agency will oversee the operations, monitoring, and security of these devices? According to this case study of Three Square Market, it seems that the FDA is assuming a role in regulating and monitoring these devices. It has been argued that a new regulatory framework needs to be developed so that the law keeps up with developments in implantable technologies.[111]

Cyborg Foundation

[edit]

In 2010, the Cyborg Foundation became the world's first international organization dedicated to help humans become cyborgs.[112] The foundation was created by cyborg Neil Harbisson and Moon Ribas as a response to the growing number of letters and emails received from people around the world interested in becoming cyborgs.[113] The foundation's main aims are to extend human senses and abilities by creating and applying cybernetic extensions to the body,[114] to promote the use of cybernetics in cultural events and to defend cyborg rights.[115] In 2010, the foundation, based in Mataró (Barcelona), was the overall winner of the Cre@tic Awards, organized by Tecnocampus Mataró.[116]

In 2012, Spanish film director Rafel Duran Torrent, created a short film about the Cyborg Foundation. In 2013, the film won the Grand Jury Prize at the Sundance Film Festival's Focus Forward Filmmakers Competition and was awarded US$100,000.[117]

In fiction

[edit]

Cyborgs are a recurring feature of science fiction literature and other media.[118][119]

Animal cyborgs

[edit]
Remote-controlled rechargeable cyborg insects[120]

The US-based company Backyard Brains released what they refer to as the "world's first commercially available cyborg" called the RoboRoach. The project started as a senior design project for a University of Michigan biomedical engineering student in 2010,[121] and was launched as an available beta product on 25 February 2011.[122] The RoboRoach was officially released into production via a TED talk at the TED Global conference;[123] and via the crowdfunding website Kickstarter in 2013,[124] the kit allows students to use microstimulation to momentarily control the movements of a walking cockroach (left and right) using a Bluetooth-enabled smartphone as the controller.

Other groups have developed cyborg insects, including researchers at North Carolina State University,[125][126] UC Berkeley,[127][128] and Nanyang Technological University, Singapore,[129][130][131][132][133] but the RoboRoach was the first kit available to the general public and was funded by the National Institute of Mental Health as a device to serve as a teaching aid to promote an interest in neuroscience.[123] Several animal welfare organizations including the RSPCA[134] and PETA[135] have expressed concerns about the ethics and welfare of animals in this project. In 2022, remote controlled cyborg cockroaches functional if moving (or moved) to sunlight for recharging were presented. They could be used e.g. for purposes of inspecting hazardous areas or quickly finding humans underneath hard-to-access rubbles at disaster sites.[136][137][120][138]

In the late 2010s, scientists created cyborg jellyfish using a microelectronic prosthetic that propels the animal to swim almost three times faster while using just twice the metabolic energy of their unmodified peers. The prosthetics can be removed without harming the jellyfish.[139][140]

Bacterial cyborg cells

[edit]

A combination of synthetic biology, nanotechnology and materials science approaches have been used to create a few different iterations of bacterial cyborg cells.[141][142][143] These different types of mechanically enhanced bacteria are created with so called bionic manufacturing principles that combine natural cells with abiotic materials. In 2005, researchers from the Department of Chemical Engineering at the University of Nebraska, Lincoln created a super sensitive humidity sensor by coating the bacteria Bacillus cereus with gold nanoparticles, being the first to use a microorganism to make an electronic device and presumably the first cyborg bacteria or cellborg circuit.[144] Researchers from the Department of Chemistry at the University of California, Berkeley published a series of articles in 2016 describing the development of cyborg bacteria capable to harvest sunlight more efficiently than plants.[145] In the first study, the researchers induced the self-photosensitization of a nonphotosynthetic bacterium, Moorella thermoacetica, with cadmium sulfide nanoparticles, enabling the photosynthesis of acetic acid from carbon dioxide.[146] A follow-up article described the elucidation of the mechanism of semiconductor-to-bacterium electron transfer that allows the transformation of carbon dioxide and sunlight into acetic acid.[147] Scientists of the Department of Biomedical Engineering at the University of California, Davis and Academia Sinica in Taiwan, developed a different approach to create cyborg cells by assembling a synthetic hydrogel inside the bacterial cytoplasm of Escherichia. coli cells rendering them incapable of dividing and making them resistant to environmental factors, antibiotics and high oxidative stress.[148] The intracellular infusion of synthetic hydrogel provides these cyborg cells with an artificial cytoskeleton and their acquired tolerance makes them well placed to become a new class of drug-delivery systems positioned between classical synthetic materials and cell-based systems.

A cyborg, short for "cybernetic organism," denotes an integrated system combining organic biological structures with artificial biomechanical or electronic components to regulate or augment physiological processes, often extending self-regulatory controls beyond innate human capacities. The term was coined in 1960 by Manfred E. Clynes and Nathan S. Kline, who envisioned cyborgs as self-regulating man-machine hybrids enabling adaptation to hostile extraterrestrial environments by automating environmental homeostasis, thereby liberating human cognition for exploration rather than mere survival. In contemporary applications, cyborg principles manifest primarily through medical interventions, such as myoelectric prostheses that harness electromyographic signals from residual muscles to control articulated limbs, thereby restoring functional mobility to individuals with amputations while interfacing directly with neural pathways. More advanced integrations include neural implants and sensory extensions, exemplified by bioartist Neil Harbisson's "eyeborg"—a cranial antenna that transduces infrared and ultraviolet wavelengths into audible vibrations, granting perception of colors beyond the visible spectrum for those with achromatopsia. Such developments underscore cyborg technology's dual role in compensating for disabilities and probing human augmentation limits. While prosthetic restorations are empirically validated for improving quality of life, experimental enhancements provoke debates on moral identity and societal equity, as biomechanical mergers challenge traditional boundaries of human agency and raise concerns over access disparities or unintended alterations to cognitive autonomy. Peer-reviewed analyses emphasize the need for rigorous clinical validation to distinguish therapeutic efficacy from speculative overreach, prioritizing causal mechanisms of integration over unsubstantiated futuristic narratives.

Definition and Conceptual Foundations

Etymology and Core Definition

The term cyborg originated as a portmanteau of "cybernetic" and "organism," coined by Manfred E. Clynes, a physiologist, and Nathan S. Kline, a psychiatrist and researcher, in their article "Cyborgs and Space," published in the September 1960 issue of Astronautics. Clynes and Kline introduced the concept in the context of space exploration, proposing that rather than engineering Earth-like environments for humans in extraterrestrial settings, bodily functions could be augmented through integrated mechanical and chemical systems to enable self-regulation and adaptation. This etymology draws from "cybernetic," rooted in the Greek kybernetes (steersman), a term popularized by Norbert Wiener in his 1948 book Cybernetics: Or Control and Communication in the Animal and the Machine to describe feedback-based control systems in organisms and machines. At its core, a cyborg is defined as a cybernetic organism—a hybrid entity where biomechanical or electronic components are integrated with biological structures to automatically compensate for or extend physiological functions, particularly in environments hostile to unaugmented life. Clynes and Kline exemplified this with a 220-gram rat implanted with an osmotic pump for continuous drug infusion, demonstrating subcutaneous self-regulation of bodily needs without external intervention. This foundational definition emphasizes proactive enhancement over mere restoration, distinguishing cyborgs from passive prosthetics by requiring seamless, feedback-driven integration that operates subconsciously, akin to natural homeostasis but amplified by technology. Subsequent scholarly interpretations retain this hybrid essence, viewing cyborgs as systems merging organic and synthetic elements to surpass inherent biological limits or mitigate deficits, though popular usage has sometimes diluted the emphasis on cybernetic control. A cyborg denotes an integrated artifact-organism system wherein exogenous components—such as biochemical regulators or electronic interfaces—extend the living organism's unconscious self-regulatory mechanisms, embedding them within the body's homeostatic processes to enable adaptation to extreme conditions, as initially proposed for extraterrestrial exploration. This hybridity requires bidirectional control loops, where the artificial elements respond to and modulate biological signals autonomously, distinguishing the cyborg from unidirectional tools or devices. Robots, by contrast, comprise fully synthetic electromechanical assemblies governed by explicit programming or sensor-driven algorithms, devoid of any originating biological substrate or intrinsic homeostatic integration. Androids, a humanoid variant of robots engineered to replicate human morphology and behaviors through advanced materials and AI, remain entirely artificial constructs without the organic augmentation paradigm central to cyborgs. Prosthetics differ primarily in scope and depth of incorporation: they function as discrete replacements for impaired anatomical structures, often relying on voluntary user input or basic mechanical linkage rather than seamless participation in systemic regulation. Cyborg enhancements, however, elevate this to organism-wide cybernetic symbiosis, where implanted or infused technologies operate subconsciously alongside physiological controls, such as automated drug dispensation synchronized with metabolic feedback. Bionics, while involving the emulation of biological efficiencies in engineered components (frequently for prosthetic applications), prioritizes functional analogy over the resultant fused entity; cyborgs embody the holistic merger of organic and mechatronic parts into a unified, self-adapting whole. This demarcation underscores the cyborg's emphasis on causal interdependence between biological vitality and technological agency, eschewing standalone mimicry for transformative physiological extension.

Evolutionary and Biosocial Perspectives

Human evolution has historically incorporated external artifacts as extensions of biological capabilities, a process akin to Richard Dawkins' concept of the extended phenotype, where tools and technologies function as heritable traits influencing survival and reproduction. Stone tools, dating to approximately 3.3 million years ago among early hominins like Australopithecus afarensis, facilitated dietary shifts and cognitive development, contributing to the enlargement of the hominin brain from around 400 cubic centimeters in early species to 1,350 cubic centimeters in modern Homo sapiens over millions of years. Cyborg technologies represent a contemporary escalation of this trajectory, integrating biomechatronic systems directly into the body to bypass the slow pace of genetic evolution, which typically requires hundreds of thousands of years for significant adaptations in humans. In this framework, cyborgization accelerates evolutionary adaptation by enabling rapid, directed enhancements that outpace natural selection. Biological evolution produced a human brain with roughly 100 trillion synapses and petaflop-level computational capacity through incremental mutations over evolutionary timescales, but technological mergers—such as brain-computer interfaces (BCIs) and neural prosthetics—allow for immediate augmentation of sensory, motor, and cognitive functions. Projections suggest widespread cyborg integration by 2050–2100, driven by advancements in neuroscience and robotics, potentially creating hybrid entities where artificial components evolve in tandem with biological ones, akin to gene-culture coevolution but amplified by intentional design. This shift may alter selection pressures, favoring individuals or populations with access to enhancements, thus introducing Lamarckian elements into human development where acquired technological traits influence future generations socially and culturally. Biosocially, cyborg technologies intersect biological capacities with social structures, potentially reshaping hierarchies and norms through disparities in enhancement access. Medical implants already demonstrate this: as of 2020, approximately 3 million individuals worldwide rely on pacemakers for cardiac function restoration, while cochlear implants number around 750,000 users by 2023, enabling auditory capabilities beyond natural limits and altering social integration for the hearing-impaired. However, non-therapeutic enhancements risk exacerbating inequalities, creating divides between enhanced elites and unenhanced populations, with implications for employment, athletics, and legal personhood—such as debates over whether cyborgs warrant distinct rights. These dynamics challenge traditional biosocial equilibria, where physical and cognitive traits evolved under egalitarian hunter-gatherer pressures, potentially leading to stratified societies stratified by technological rather than genetic inheritance, as cautioned in analyses of human augmentation ethics. Empirical data from current prosthetic markets, projected to grow from $1.5 billion in 2005 to $3.8 billion by 2030, underscore the scalability of such integrations and their societal ripple effects.)

Historical Origins and Development

Early Theoretical Foundations (1960s)

The concept of the cyborg emerged in 1960 as a theoretical framework for augmenting human physiology to enable survival in extraterrestrial environments, proposed by Manfred E. Clynes, a physiologist and research scientist at Rockland State Hospital's Dynamic Simulation Laboratory, and Nathan S. Kline, a psychiatrist and psychopharmacologist known for his work in psychotropic drugs. In their article "Cyborgs and Space," published in the September 1960 issue of Astronautics, a journal of the American Rocket Society, they introduced the term "cyborg" as a portmanteau of "cybernetic organism" to describe a self-regulating system integrating mechanical and electronic devices with the human body for automatic environmental adaptation. This idea built on cybernetics principles, emphasizing feedback loops for homeostasis, but shifted focus from enclosing humans in life-support capsules to implanting regulatory mechanisms—such as osmoregulators for fluid balance or chemical dispensers for metabolism—to allow physiological adaptation without constant reliance on external engineering. Clynes and Kline argued that traditional approaches to space travel, which prioritized replicating Earth's conditions through cumbersome suits and habitats, were inefficient for long-duration missions, as evidenced by the physiological stresses observed in early suborbital flights and animal experiments. They envisioned cyborg enhancements enabling humans to "go into space as is," with devices handling deviations in gravity, radiation, or atmospheric pressure via pre-programmed or adaptive controls, thereby optimizing performance in non-terrestrial settings. This theoretical model drew from empirical data on human homeostasis under stress, including Kline's research on pharmacological interventions for mental and physical regulation, and Clynes' simulations of dynamic physiological responses. Their proposal aligned with the intensifying U.S.-Soviet space race, prompting NASA to commission feasibility studies on cyborg applications shortly after publication, though implementation remained speculative. The 1960s theoretical discourse on cyborgs remained largely conceptual, with limited extensions beyond Clynes and Kline's foundational work, as subsequent discussions emphasized ethical and technical hurdles over immediate prototyping. Critics within scientific circles, including cyberneticists, noted the challenges of biocompatibility and long-term integration, yet the concept influenced broader debates on human-machine symbiosis, foreshadowing applications in prosthetics and environmental adaptation. No peer-reviewed empirical validations of full cyborg systems occurred in the decade, underscoring the idea's status as a forward-looking hypothesis grounded in observed limits of unaugmented human endurance in extreme conditions.

Key Milestones in Implementation

The first practical implementation of cyborg technology occurred on October 8, 1958, when Swedish surgeons Åke Senning and Rune Elmqvist implanted the world's initial fully implantable pacemaker into patient Arne Larsson at Karolinska University Hospital in Stockholm; the battery-powered device, containing 26 mercury cells, regulated his heartbeat via electrodes sutured to the heart, marking the debut of electronic augmentation for vital organ function. Larsson outlived the device's three-hour battery life expectancy, undergoing 26 replacements over decades until his death in 2001 at age 86. In 1961, American otologist William House performed the earliest documented cochlear implant surgery, embedding electrodes into the cochlea of a patient to stimulate auditory nerves directly with electrical signals, though initial results were rudimentary and single-channel systems predominated until multi-electrode advancements in the 1970s by Graeme Clark enabled broader speech perception restoration. These devices represented early neural interfaces, converting external sounds into impulses bypassing damaged ear structures, with FDA approval for wider use following in 1985 after refinements in electrode arrays and speech processing. Pioneering brain-computer interface (BCI) efforts emerged in the mid-1990s, with Philip Kennedy implanting the first cortical neuroprosthesis in human patient Johnny Ray in 1997; the glass-encased electrode array, developed by Neural Signals Inc., decoded motor intent from brain signals to control a robotic arm via thought, achieving basic cursor movement after training despite signal degradation over months. This marked a shift from restorative to potentially communicative cybernetic integration, though limited by invasive electrode scarring. On August 24, 1998, cybernetics professor Kevin Warwick underwent the inaugural human implantation of a subcutaneous RFID microchip at University College London, enabling wireless door access and computer interaction as part of Project Cyborg's initial phase to test human-machine symbiosis. In March 2002, Warwick advanced to a 100-electrode array implanted in his median nerve, allowing bidirectional neural signaling with a robotic hand and his wife's implant, demonstrating remote sensory extension and voluntary control over external actuators. Enhancement-focused milestones intensified in 2004, when artist Neil Harbisson received a permanent skull-implanted antenna (eyeborg) connecting his occipital bone to auditory nerves, transducing infrared and ultraviolet light frequencies into bone-conducted sound vibrations to overcome congenital achromatopsia, thereby expanding perceptual capabilities beyond natural human limits. This self-initiated augmentation, approved as prosthetic identity in official documents, exemplified voluntary sensory prosthesis fusion, influencing subsequent biohacker implants for non-medical extension.

Evolution from Restoration to Enhancement

Cyborg technologies originated primarily as restorative devices to compensate for organ failure or limb loss. The inaugural fully implantable cardiac pacemaker was inserted on October 8, 1958, by surgeon Åke Senning and biomedical engineer Rune Elmqvist at Sweden's Karolinska Institute, allowing patient Arne Larsson, who suffered from complete heart block, to live an additional 43 years. This device electrically stimulated the heart to maintain rhythm, marking an early fusion of electronics with human physiology to restore vital functions. Similarly, the first cochlear implant occurred in 1961, when William House and John Doyle electrically stimulated the auditory nerve in a deaf patient, initiating efforts to rehabilitate hearing loss through direct neural interfacing. Prosthetic advancements paralleled this, shifting from rudimentary mechanical replacements to electronically controlled systems. In the 1960s, myoelectric prostheses emerged, using surface electromyography signals to drive limb movement, as demonstrated by the Soviet bioelectric hand developed around 1963, which restored basic grasping for upper-limb amputees. These innovations prioritized functional recovery to approximate pre-impairment capabilities, with over 3 million pacemakers implanted globally by 2014. The paradigm evolved toward enhancement in the late 20th and early 21st centuries, propelled by military research and bioengineering breakthroughs enabling capabilities exceeding natural human limits. DARPA's Revolutionizing Prosthetics program, launched in 2006, produced neurally controlled prosthetic arms like the DEKA Luke Arm, integrating targeted muscle reinnervation for intuitive, multi-degree-of-freedom operation that outperformed conventional devices in dexterity and feedback. Exoskeletons followed suit, progressing from rehabilitative gait trainers like the 2001 Lokomat for spinal cord injury patients to augmentation systems such as DARPA-funded powered suits designed to boost soldier load-carrying capacity and reduce fatigue. Sensory and cognitive enhancements further exemplified this transition. In 2004, artist Neil Harbisson underwent implantation of an "eyeborg" antenna at his skull's base, transducing light frequencies—including infrared and ultraviolet—into audible vibrations, thereby augmenting colorblind perception beyond typical human visual range. Deep brain stimulators, FDA-approved for Parkinson's disease in 1997, have been explored for memory enhancement in healthy subjects via programs like DARPA's RESTORE, illustrating how therapeutic neural modulation extends to performance optimization. This shift, fueled by miniaturization of components and refined human-machine interfaces, has increasingly prioritized augmentation over mere restoration, raising questions about equitable access and long-term physiological integration.

Technological Underpinnings

Biomechatronic Components and Interfaces

Biomechatronic components in cyborg systems encompass sensors, actuators, control algorithms, and power sources designed to integrate mechanical and electronic elements with biological tissues for enhanced functionality. Sensors detect biosignals such as electromyographic (EMG) activity from muscles or neural impulses, enabling real-time feedback for adaptive control. Actuators, including electric motors and pneumatic systems mimicking muscle contraction, provide powered movement that can exceed natural human capabilities, as seen in powered prosthetic ankles delivering net positive mechanical energy during locomotion. Control systems process these inputs via embedded microprocessors running algorithms that emulate neuromuscular dynamics, ensuring seamless human-machine synchronization. Interfaces form the critical junction between biological and synthetic elements, with mechanical attachments like osseointegration achieving direct skeletal fixation. In osseointegration, a titanium fixture is surgically implanted into residual bone, allowing ingrowth for stable anchorage, followed by an abutment that connects to the prosthetic component, reducing socket-related issues like pistoning and improving proprioceptive feedback. The OPRA Implant System, approved for above-knee amputees, utilizes seven titanium parts implanted in staged surgeries to enable load-bearing prosthetic attachment. Neural interfaces, such as brain-machine interfaces (BMIs), facilitate direct cortical control by recording and decoding neural signals to command actuators, with invasive electrode arrays offering higher resolution than non-invasive alternatives like EEG. These systems, advanced by researchers like Hugh Herr at MIT's Biomechatronics Group, integrate agonist-antagonist myoneural interfaces (AMI) to restore bidirectional neural communication, allowing users to perceive limb position and force through reinnervated muscles. Challenges in these interfaces include biocompatibility to prevent rejection and signal stability over time, addressed through materials like titanium alloys and bio-inspired designs that minimize tissue inflammation. For instance, Herr's group has developed bionic limbs with variable impedance control, where prosthetic knees adapt to gait phases using EMG-derived intent recognition, outperforming passive devices in energy efficiency. Power sources, often lithium-polymer batteries, must balance longevity with miniaturization, supporting continuous operation for ambulatory cyborg applications. Empirical outcomes from clinical trials demonstrate osseointegrated prostheses improve walking speed by up to 25% and reduce energy expenditure compared to socket prosthetics.

Cyborg Tissues and Materials in Engineering

Cyborg tissues in engineering integrate living cellular components with synthetic electronic materials to create functional hybrid systems that mimic or exceed natural tissue capabilities. These constructs typically employ biocompatible scaffolds, such as hydrogels or decellularized extracellular matrices, embedded with conductive nanomaterials like carbon nanotubes, graphene, or gold nanowires, to enable electrical signaling and mechanical actuation within biological environments. The approach addresses limitations in traditional tissue engineering by incorporating real-time sensing and feedback mechanisms, facilitating applications in neural interfaces, cardiac patches, and prosthetic integrations. Key material innovations include stretchable nanoelectronics that conform to dynamic tissue growth without eliciting immune rejection. For instance, in 2023, Harvard researchers developed mesh nanoelectronics embedded in human-induced pluripotent stem cell-derived cardiac microtissues, achieving chronic electrophysiological mapping over weeks and demonstrating how endothelial cells enhance cardiomyocyte maturation through paracrine signaling. These networks, fabricated via processes like photolithography and transfer printing onto gelatin-based hydrogels, support three-dimensional tissue architectures while maintaining signal fidelity above 90% post-implantation. Similarly, biohybrid neural interfaces utilize soft polydimethylsiloxane (PDMS) substrates with interwoven metallic microwires, promoting seamless integration with brain or muscle tissues for augmentation. Engineering challenges center on achieving long-term biocompatibility and vascularization in these hybrids. Conductive polymers like poly(3,4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS) are commonly doped into collagen matrices to form electronically active tissues, but degradation rates must match tissue remodeling, typically spanning 6-12 months in vivo. Advances in 3D bioprinting enable precise layering of cellular inks with electronic filaments; a 2020 review highlighted extrusion-based methods yielding cyborg organoids with embedded sensors for monitoring pH, oxygen, and contraction force in real time. In cardiac applications, cyborg organoids fuse cardiomyocytes with flexible electrodes, allowing optogenetic stimulation and force generation up to 1.5 mN/mm², surpassing non-hybrid engineered tissues. Recent progress extends to regenerative bioelectronics for human augmentation. By February 2025, bio-inspired soft electronics had evolved to include "living" interfaces where neural probes self-heal via polymer crosslinking, reducing fibrosis by 70% compared to rigid silicon implants in rodent models. In developmental studies, flexible bioelectronic devices implanted into Xenopus laevis tadpole embryos in June 2025 formed hybrid heart and brain organoids, tracking neural activity with 95% electrode survival through metamorphosis, underscoring potential for scalable augmentation platforms. These materials prioritize causal integration—ensuring electronic components influence biological processes without dominating them—over mere prosthetic replacement, though clinical translation remains limited by scalability and ethical constraints on enhancement.

Integration Challenges and Feedback Systems

One primary challenge in cyborg integration involves biocompatibility, where implanted devices trigger foreign body reactions including inflammation, gliosis, and scar tissue formation that encapsulate electrodes and degrade neural signal quality over time. These responses arise from mechanical mismatch between rigid implants and soft tissue, leading to chronic irritation and progressive signal attenuation, with studies showing electrode impedance rising significantly within months post-implantation due to protein adsorption and cellular encapsulation. Efforts to mitigate this include drug-eluting coatings like dexamethasone, which reduce immune activation and fibrosis in animal models, though human long-term efficacy remains limited by variable immune responses across individuals. Neural interfaces face additional hurdles in signal stability and fidelity, particularly for invasive brain-computer interfaces (BCIs) that penetrate cortical tissue, risking vascular damage, infection, and neuronal loss while suffering from low signal-to-noise ratios that worsen with gliotic scarring. Long-term recordings often exhibit degradation, with non-invasive alternatives like EEG providing poorer spatial resolution and susceptibility to motion artifacts, necessitating advanced decoding algorithms to filter noise but introducing latency that impairs real-time control. Inter-subject variability in neural patterns further complicates calibration, requiring extensive training data and adaptive models, as evidenced by BCI systems where performance drops after initial sessions due to neuroplastic shifts or electrode migration. Feedback systems are essential for closed-loop cyborg operation, enabling sensory restoration to guide motor commands, yet implementing bidirectional communication remains problematic due to the complexity of encoding naturalistic touch or proprioception via electrical stimulation. In prosthetic limbs, absence of tactile feedback results in imprecise grasping and higher cognitive load, with experimental neuroprostheses attempting somatosensory stimulation of residual nerves or cortex showing improved control but limited by unnatural sensations and fatigue from mismatched timing. Recent advancements, such as targeted cortical microstimulation calibrated to elicit realistic textures, have restored basic discrimination in trials as of January 2025, though scalability is hindered by electrode durability and the need for personalized mapping to avoid overstimulation-induced plasticity disruptions. Overall, these challenges underscore the causal primacy of tissue-device interfaces in limiting cyborg efficacy, with ongoing research prioritizing flexible, bioresorbable materials and AI-driven feedback loops to approximate native sensorimotor integration.

Applications in Human Augmentation

Medical and Rehabilitative Uses

Cyborg technologies in medicine focus on restoring physiological functions through direct integration of electronic and mechanical systems with human biology, particularly for patients with organ failure, sensory loss, or motor impairments. Cardiac pacemakers exemplify early applications, with the first fully implantable device invented by Wilson Greatbatch and surgeon William Chardack in 1958 and successfully implanted in a human patient on April 8, 1960, to treat complete heart block. By 2023, over 1 million pacemakers are implanted annually worldwide, significantly reducing mortality from arrhythmias by maintaining stable heart rates via electrical stimulation synchronized with cardiac cycles. Sensory restoration via neural prosthetics has advanced with cochlear implants, which bypass damaged inner ear hair cells to directly stimulate the auditory nerve. Approved by the FDA in 1984 for adults and later for children, these devices enable open-set speech recognition in 82% of postlingually deafened adults and 53% of prelingually deafened individuals, with average improvements in sentence recognition scores exceeding 50% post-implantation. Retinal prostheses, such as epiretinal or subretinal arrays, target degenerative conditions like retinitis pigmentosa; clinical trials demonstrate restoration of basic light perception and object recognition, though visual acuity remains limited at around 20/1260—far below legal blindness thresholds—with patients achieving phosphene-based navigation in controlled settings. Motor rehabilitation employs bionic limbs and exoskeletons interfaced with residual nerves or muscles. Myoelectric prosthetics, controlled via electromyographic signals, restore upper-limb function in amputees, with advanced models incorporating sensory feedback loops to mimic tactile sensation; clinical data show users achieving up to 80% of contralateral hand dexterity in tasks like grasping. Lower-limb exoskeletons, such as powered orthoses for spinal cord injury patients, facilitate gait retraining; a 2023 randomized trial of the HANK exoskeleton reported significant gains in walking independence, with 70% of participants improving 6-minute walk distances by over 50 meters after 12 weeks of use, alongside reduced spasticity via promoted neuroplasticity. Brain-computer interfaces (BCIs) enable direct neural control for paralysis rehabilitation, decoding intent from cortical signals to drive functional electrical stimulation or robotic actuators. In post-stroke patients, BCI-assisted training yields modest but statistically significant motor improvements, with meta-analyses indicating 10-20% gains in upper-limb Fugl-Meyer scores after 20-30 sessions, attributed to reinforced synaptic plasticity rather than mere compensation. These systems, often non-invasive via EEG or invasive via implanted electrodes, prioritize safety, with adverse event rates below 5% in trials, though long-term efficacy depends on patient-specific neural remodeling. Empirical outcomes underscore causal links between repeated interface use and functional recovery, countering skepticism by quantifying neural adaptations via fMRI correlates.

Military and Tactical Enhancements

Military applications of cyborg technologies focus on augmenting soldier capabilities through biomechanical and neural integrations, primarily driven by U.S. Defense Advanced Research Projects Agency (DARPA) programs aimed at enhancing strength, endurance, sensory perception, and cognitive control in tactical environments. These efforts seek to address physical limitations in combat, such as load-bearing fatigue and injury recovery, while exploring direct brain-machine interfaces for weapon or drone operation. Empirical testing has demonstrated potential reductions in metabolic cost for locomotion via powered exoskeletons, though full-field deployment remains limited by power, weight, and integration challenges. Exoskeletons represent a primary vector for tactical enhancement, designed to amplify human physical performance by offloading weight and boosting mobility. The U.S. Special Operations Command's Tactical Assault Light Operator Suit (TALOS) program, initiated in 2013, invested $80 million over six years to develop a powered exoskeleton integrating armor, sensors, and actuators for special operators, but was terminated in 2019 due to insurmountable technical hurdles including battery life and thermal management, with components repurposed for other systems. Subsequent U.S. Army initiatives, informed by DARPA-funded prototypes tested on soldiers in 2015, prioritize logistic support over direct combat, enabling troops to carry up to 100-pound loads with reduced fatigue during extended marches, as validated in field trials at Aberdeen Proving Ground. These devices, often battery-powered and lower-limb focused, have shown up to 20% improvement in walking economy in controlled studies, though real-world tactical efficacy depends on terrain adaptability and user training. Advanced prosthetics for wounded personnel further embody cyborg principles, restoring or surpassing baseline functionality through neural control and sensory feedback. DARPA's Revolutionizing Prosthetics program, launched in 2006, produced the Modular Prosthetic Limb (MPL), a dexterous upper-limb system weighing 9 pounds with 22 degrees of freedom, tested on amputee volunteers including military veterans, enabling tasks like grasping objects with force feedback via implanted electrodes. The program's successor, the Luke Arm (DEKA Gen2), approved by the FDA in 2014 for clinical use, incorporates pattern recognition for intuitive control, priced at approximately $250,000 per unit, and has been deployed to over 100 U.S. service members for rehabilitation, demonstrating grip strengths exceeding 25 pounds in empirical evaluations. These integrations rely on targeted muscle reinnervation surgery to interface residual nerves with actuators, prioritizing empirical outcomes over speculative enhancements. Neural interfaces offer prospective tactical advantages by enabling thought-based command of systems, potentially accelerating decision cycles in combat. DARPA's Next-Generation Nonsurgical Neurotechnology (N3) program, started in 2018, develops bidirectional, non-invasive brain-computer interfaces (BCIs) using ultrasound or magnetic fields to read and write neural signals, aiming for applications like remote drone swarming or augmented target acquisition without surgical invasion. A 2016 DARPA initiative allocated millions for injectable neural implants to bridge human cognition with computers, with prototypes tested for controlling cursors or prosthetics at speeds up to 100 bits per minute in able-bodied subjects. RAND Corporation assessments project BCIs could monitor cognitive workload or suppress fear responses via targeted neuromodulation, enhancing operational resilience, though ethical and reliability concerns persist, as evidenced by variable accuracy rates below 90% in high-stress simulations. U.S. Army research from 2019 envisions "neuro-silica" enhancements for direct neural targeting by 2050, but current implementations remain experimental, confined to laboratory settings due to biocompatibility and signal noise issues.

Performance Optimization in Sports and Labor

In sports, cyborg enhancements for performance optimization have centered on prosthetic limbs integrated with amputee athletes' bodies, enabling participation in events like sprinting and jumping while raising questions about fairness. Biomechanical studies of lower-limb prostheses, such as carbon-fiber "blades," reveal no net advantage in maximum sprint velocities over biological legs for distances up to 400 meters, as energy return from the prosthetics aligns closely with human muscle efficiency without exceeding it. For instance, kinematic analyses of elite blade runner Hunter Woodhall, who holds world records in Paralympic events, demonstrate that his prostheses facilitate comparable ground reaction forces and stride mechanics to non-amputee sprinters, debunking claims of inherent superiority. In long jump, however, below-knee amputees employing prostheses achieve takeoff techniques that optimize horizontal velocity, allowing performances approaching able-bodied world records, as evidenced by simulations showing enhanced limb compliance and reduced energy loss during push-off. Emerging integrations, such as powered exoskeletons or neural-linked devices, remain experimental for sports, with prototypes tested for reflex augmentation but lacking empirical validation in elite competition due to regulatory bans on enhancements conferring unfair advantages, as seen in the International Association of Athletics Federations' 2007 ruling against certain prosthetic designs. These technologies prioritize restoration over superhuman gains, with peer-reviewed data indicating improved endurance and injury resistance for users but no transcendence of physiological limits in controlled trials. In labor contexts, passive and powered exoskeletons represent practical cyborg integrations that enhance worker productivity by offloading biomechanical loads during repetitive tasks. Field trials in distribution centers using devices like the Apex 2 exosuit reported an 8% increase in units handled per hour, alongside sustained reductions in metabolic cost and fatigue over multi-hour shifts. Systematic reviews of occupational applications, including assembly lines and construction, quantify benefits such as 39% lower physical effort, 30% decreased back strain, and elevated task endurance, particularly for overhead or lifting activities exceeding 10 kg. Case studies from automotive manufacturing demonstrate that shoulder-support exoskeletons maintain output quality while mitigating musculoskeletal disorder risks, with workers reporting subjective comfort improvements after 4-6 weeks of adaptation. Despite these gains, implementation challenges include initial discomfort and potential cognitive distractions, underscoring the need for task-specific fitting to avoid diminishing returns. Overall, such systems yield verifiable productivity uplifts in industrial settings without altering core human capabilities, focusing instead on ergonomic augmentation.

Non-Human and Hybrid Cyborgs

Animal and Insect Cyborgs

Cyborg insects merge living insects with microelectronic implants to enable remote control of locomotion and sensory functions, primarily through neural or muscular stimulation. The U.S. Defense Advanced Research Projects Agency (DARPA) launched the Hybrid Insect Micro-Electro-Mechanical Systems (HI-MEMS) program in 2006 to engineer such hybrids by embedding electronics during the pupal stage, facilitating integration with the developing nervous system for applications in surveillance and reconnaissance. Implants typically include electrodes for delivering electrical pulses to flight or leg muscles, allowing directional steering over distances up to 100 meters via radio signals. Beetles have been prominent subjects due to their robust flight and load-bearing capacity. In 2015, researchers at the University of California, Berkeley demonstrated remote-controlled cyborg beetles equipped with lightweight backpacks containing electrodes implanted into the brain and flight muscles of Mecynorrhina torquata beetles, enabling takeoff, turning, and landing commands with response times under 0.5 seconds. More recently, in 2025, the University of Queensland developed "ZoBorg" cyborgs using Zophobas morio beetles fitted with neural interfaces, achieving on-demand climbing of vertical walls and navigation over obstacles at speeds up to 0.2 m/s, targeted for urban search-and-rescue operations in collapsed structures. Cockroaches represent another focus for ground-based mobility in confined spaces. A 2025 study introduced light-driven cyborg cockroaches using non-invasive UV illumination to guide Blaberus discoidalis without surgical implants, leveraging optogenetic principles for directional control while minimizing tissue damage and extending operational lifespan beyond traditional electrode methods. Complementary research has advanced swarm coordination, with cyborg cockroaches demonstrating collective navigation through soft, obstructed terrains via biphasic pulse stimulation for balanced charge and reduced neural fatigue. Broader animal cyborg efforts remain exploratory, often emphasizing insects' scalability over vertebrates. For instance, a 2024 prototype integrated electronic actuators with jellyfish (Aurelia aurita) for controlled propulsion in aquatic environments, exploiting the organism's innate pulsation for energy-efficient soft robotics, though scalability to larger animals like rats for tasks such as odor detection has faced persistent challenges in biocompatibility and control precision. These developments highlight insects' advantages in power autonomy and stealth, with battery-free solar-rechargeable modules extending mission durations to hours without recharging. Empirical tests confirm survival rates post-implantation exceeding 80% in select species, underscoring viable integration despite ethical concerns over animal welfare.

Bacterial and Cellular Cyborgs

Bacterial cyborgs refer to biohybrid systems in which prokaryotic cells, typically Escherichia coli, are integrated with synthetic materials to form semi-living entities capable of enhanced environmental responsiveness, motility, or functionality beyond natural biological limits. These constructs often involve intracellular hydrogelation, where biocompatible polymers such as polyethylene glycol diacrylate (PEGDA) are polymerized within the cell cytoplasm using light-activated initiators, creating a supportive scaffold that immobilizes the cytoskeleton and prevents replication while preserving metabolic processes like protein synthesis and ATP production. This approach, first detailed in January 2023, yields non-dividing cells resistant to stressors such as hydrogen peroxide and antibiotics, enabling prolonged viability in harsh conditions unsuitable for unmodified bacteria. Such cyborg bacteria demonstrate potential in biomedical applications, including targeted cancer therapy, where engineered E. coli variants penetrate tumor microenvironments, degrade diseased tissue, and resist immune clearance due to their synthetic augmentations. For instance, hydrogel-embedded bacteria maintain motility via flagella and can be loaded with therapeutic payloads, outperforming traditional nanoparticles in hypoxic tumor navigation. In environmental remediation, these cells sense pollutants and catalyze degradation reactions, leveraging their retained enzymatic activity within the artificial matrix. Architectural variations, explored in 2024, incorporate alternative photoinitiators and hydrogel compositions to tune mechanical properties, enhancing adaptability for microrobotic tasks like microscale transport. Cellular cyborgs extend this paradigm to broader eukaryotic or prokaryotic frameworks, often via biohybrid interfaces with nanomaterials or electronics. In one 2024 development, Shewanella oneidensis bacteria were combined with flexible sensor arrays to form living bioelectronic patches that detect tissue damage signals, such as lactate, and release healing agents like antimicrobial peptides in response. Earlier electronic integrations, achieved in 2016, linked modified bacteria to computational systems through optogenetic interfaces, allowing light-mediated control of bacterial gene expression for real-time environmental monitoring or synthetic signaling circuits. Inorganic coatings, such as metal-organic frameworks applied in 2025 biohybrids, augment bacterial catalysis for solar-driven nitrogen fixation, achieving conversion efficiencies exceeding 10% under ambient conditions by interfacing photosynthetic semiconductors with microbial reductases. Magnetically actuated biohybrid systems further illustrate propulsion-enhanced cellular cyborgs, where bacteria propel synthetic microparticles in 3D biological matrices for drug delivery, as demonstrated in a 2022 study using Magnetospirillum magneticum strains coated with iron oxide for precise navigation under external fields. These constructs exploit bacterial chemotaxis for autonomous targeting, reducing reliance on energy-intensive artificial swimmers. Challenges include maintaining long-term stability of the bio-synthetic interface, as polymer degradation or immune recognition can limit efficacy, though empirical data indicate cyborg cells sustain function for days to weeks in vitro. Ongoing research prioritizes scalability and biocompatibility to transition from proof-of-concept to clinical or industrial deployment.

Biochimerism and Synthetic Hybrids

Biochimerism refers to artificial chimerism, a form of hybridity in synthetic biology where natural biological systems incorporate synthetic genetic or cellular components, resulting in biocyborgs that blend organic and engineered biological elements at the molecular level, unlike traditional cyborgs reliant on mechatronic interfaces. This approach leverages tools like CRISPR gene editing and synthetic genome design to create organisms with modified heredity and function, often tested first in non-human models such as bacteria and yeast to enable permanent physiological alterations. In practice, artificial chimerism has been demonstrated through synthetic chromosome assembly in yeast, where researchers used the CReATiNG method to recombine chromosomes across strains and species, modifying structures and deleting large gene clusters to study genetic interactions beyond natural limits; this 2023 advancement facilitates scalable DNA manipulation exceeding 100 kb in length. Such techniques draw from broader synthetic biology efforts, including the Human Genome Project-write (initiated around 2016), which proposes de novo synthesis of complex genomes for model organisms to probe evolutionary and functional biology. Synthetic hybrids extend this paradigm to cellular-level integrations, exemplified by cyborg bacterial cells created in 2023, in which a synthetic polymer hydrogel network is polymerized intracellularly to halt cell division while maintaining metabolic and motility functions, conferring resistance to antibiotics, osmotic stress, and UV radiation. Developed by teams at Academia Sinica and the University of California, Davis, these semisynthetic entities—approximately half-living, half-artificial—offer potential for environmental remediation and targeted therapeutics by combining biological adaptability with engineered durability. Further examples include biohybrid microrobots propelled by chimeric bacterial-synthetic constructs, where flagellated bacteria are interfaced with artificial microstructures for autonomous navigation and drug release; a 2022 protocol highlighted their use in penetrating biological barriers like mucus, achieving speeds up to 200 body lengths per second under magnetic guidance. These non-human systems underscore causal mechanisms of enhanced performance through symbiotic biological propulsion and synthetic control, though scalability remains limited by biocompatibility and organism viability.

Societal Impacts and Ethical Debates

Achievements and Empirical Benefits

Cochlear implants represent a major achievement in cyborg technology, enabling profound restoration of hearing in individuals with severe sensorineural deafness. Clinical outcomes show that 82% of adults with postlingual hearing loss achieve improved speech perception post-implantation, while overall device functionality success exceeds 95%, with rejection rates under 0.2%. These implants integrate directly with the auditory nerve, bypassing damaged cochlea to deliver electrical signals that the brain interprets as sound, thereby facilitating communication, environmental awareness, and social integration for recipients. Bionic prosthetics have empirically enhanced mobility and dexterity for amputees, allowing performance of tasks rivaling natural limbs. Neural-integrated prosthetic hands provide tactile feedback, enabling users to sense object shapes and movements with reported improvements in grasp precision for items like cups or tools. Recipients have demonstrated capabilities such as completing marathons or returning to military service, underscoring functional benefits beyond mere replacement. Brain-computer interfaces as neural implants have yielded benefits for those with paralysis, permitting thought-controlled operation of computers and communication devices. In documented trials, participants gained independence in tasks like web navigation and conversation, with sustained signal stability enhancing daily autonomy. These outcomes stem from direct cortical electrode arrays decoding neural intent into actionable outputs, though long-term efficacy varies by implantation site and individual physiology. Cyborg insects, such as electronically augmented cockroaches and beetles, have achieved superior navigation in cluttered terrains compared to autonomous robots, with applications in disaster response. Controlled swarms demonstrate coordinated search capabilities in hazardous areas, leveraging biological agility for tasks like victim location where wheeled or flying drones falter. Empirical tests confirm high success in maze traversal and environmental scouting, powered by lightweight neural stimulators.

Criticisms, Risks, and Unfounded Fears

Critics of cyborg technologies highlight substantial health risks associated with neural implants and other invasive augmentations, including insertion injuries and foreign body responses that degrade signal quality over time. Surgical implantation procedures carry documented dangers such as infection, bleeding, and device migration, which can cause neurological damage or therapeutic failure. In Neuralink's preclinical trials reported in 2025, 15 of 30 tested monkeys died following implantation, though company statements attributed these outcomes to underlying conditions rather than the device itself. Long-term abandonment risks also persist, as evidenced by cases where neurotechnology firms ceased support, leaving patients without maintenance for essential implants. Security vulnerabilities in brain-computer interfaces pose acute risks of "brainjacking," where unauthorized access could halt stimulation, drain batteries, induce tissue damage, or extract personal neural data. Malicious actors might remotely hijack devices to compel physical actions or manipulate thoughts, exploiting bidirectional data flows in systems like those developed by Neuralink. Such threats extend to irreversible cognitive alterations from hacked neural signals, underscoring the need for robust encryption absent in many current prototypes. Societal criticisms emphasize how cyborg enhancements could exacerbate inequality by favoring those with financial means, creating a divide between augmented elites and unenhanced populations. Ethical debates question the boundary between therapeutic restoration and non-medical enhancement, arguing that the latter undermines human autonomy and invites coercion through privacy erosions from constant neural monitoring. Bioethicists further contend that widespread adoption risks commodifying the body, prioritizing technological integration over inherent human capabilities. Unfounded fears often invoke dystopian scenarios of cyborgs leading to collective assimilation akin to fictional Borg collectives or monstrous dehumanization, despite lacking empirical basis in current technologies that enhance rather than supplant agency. Apprehensions of inevitable loss of free will or societal collapse from transhumanist pursuits overlook incremental, reversible augmentations observed in medical prosthetics, where users retain volition without existential overhaul. These speculative alarms, rooted in cultural mythology, divert attention from verifiable risks without corresponding evidence of mass-scale threats.

Regulatory Frameworks and Future Trajectories

In the United States, the Food and Drug Administration (FDA) classifies implantable brain-computer interfaces (BCIs) and neural implants as Class III medical devices, requiring premarket approval through rigorous clinical trials to demonstrate safety and efficacy for therapeutic purposes such as treating paralysis or amputation-related impairments. The FDA issued specific guidance on May 20, 2021, outlining nonclinical testing and investigational device exemption requirements for implanted BCIs, emphasizing biocompatibility, electromagnetic compatibility, and long-term durability to mitigate risks like tissue damage or signal degradation. Recent approvals, such as the April 2025 clearance of Precision Neuroscience's Layer 7 cortical interface for temporary implantation up to 30 days, illustrate incremental progress under this framework, limited to diagnostic and monitoring uses rather than permanent enhancements. Non-therapeutic human augmentation, such as cognitive or physical enhancements for healthy individuals, falls into regulatory gaps, often evading oversight unless classified as investigational, which raises concerns over unverified long-term effects like neural inflammation or psychological dependency. Internationally, regulatory approaches remain fragmented, with the European Medicines Agency (EMA) treating advanced prosthetics and neural devices under the Medical Device Regulation (MDR) 2017/745, which mandates conformity assessments but lacks tailored provisions for cyborg-like integrations beyond restorative functions. In jurisdictions like China and the United States, statutes on technologically enhanced individuals focus on liability and consent in civil contexts, but military applications—such as DARPA-funded exoskeletons—operate under defense-specific protocols with minimal public transparency, potentially enabling dual-use technologies for both rehabilitation and tactical superiority. Existing frameworks prioritize risk-based classification, yet they undervalue competitive dynamics among states, where laxer regimes could accelerate enhancements, as evidenced by varying approval timelines for cochlear implants, approved in the U.S. since 1984 but delayed elsewhere until the 1990s. Ethical guidelines, often proposed in academic literature, advocate for voluntary consent and equity assessments but frequently reflect precautionary biases, overemphasizing speculative harms without sufficient empirical validation from longitudinal studies on early cyborg precedents like pacemakers, implanted in over 1 million patients annually with complication rates below 5%. Future trajectories suggest evolving toward adaptive, technology-agnostic regulations to address accelerating integrations, such as wireless neural links projected to achieve bidirectional brain-machine communication by 2030, necessitating updates to privacy laws under frameworks like HIPAA to protect augmented cognition from unauthorized data extraction. Proposals for international standards, including dual-use oversight for civil-military crossovers, aim to prevent unregulated proliferation while fostering innovation, though enforcement challenges persist amid geopolitical rivalries. Empirical data from current deployments indicate that flexible, evidence-driven policies—balancing safety thresholds with performance metrics—could mitigate risks like socioeconomic disparities, where enhancements might exacerbate inequalities if access remains cost-prohibitive, estimated at $10,000–$50,000 per implant. Absent proactive reforms, trajectories point to patchwork governance, potentially stifling verifiable benefits like restored mobility in 80% of BCI trial participants, while inviting overregulation influenced by unsubstantiated fears rather than causal analyses of failure modes.

Cultural and Philosophical Dimensions

Cyborg in Cultural Theory

In cultural theory, particularly in Donna Haraway's 1985 essay "A Cyborg Manifesto: Science, Technology, and Socialist-Feminism in the Late Twentieth Century," the cyborg serves as a metaphorical boundary figure that transgresses traditional dualisms such as human/animal, organism/machine, and physical/non-physical, rejecting unified notions of identity and essence. Haraway employs the cyborg to represent hybrid socio-technical assemblages in which agency, personhood, and responsibility are distributed across bodies, devices, and institutions rather than confined to a single organic individual, emphasizing partial connections, affinity over identity, and the informatics of domination in late twentieth-century technoculture. This framework has influenced discussions in feminism, postmodernism, and science studies by highlighting feedback relations that shape subjectivity in technologically saturated environments.

Representations in Fiction and Media

![Noun_Borg_14249.svg.png][float-right] Cyborg representations in fiction frequently explore the boundaries between human identity and technological augmentation, often portraying characters who grapple with retained humanity amid mechanical enhancements. Early literary depictions include Edgar Allan Poe's 1839 short story "The Man That Was Used Up," which features General John A. B. C. Smith, a figure revealed to be assembled from advanced prosthetic limbs and organs, satirizing reliance on artificial replacements. E. V. Odle's 1923 novel The Clockwork Man presents the first explicit cyborg protagonist, a 27th-century time traveler whose organic body houses intricate mechanical time-travel mechanisms, highlighting themes of predestination and mechanical determinism. In mid-20th-century science fiction, cyborg tropes evolved to include bionic reconstruction for survival or enhancement, as seen in the 1974-1978 television series The Six Million Dollar Man, where astronaut Steve Austin is rebuilt with cybernetic limbs granting superhuman strength, speed, and vision after a crash, embodying post-World War II optimism about prosthetic technology. Film portrayals intensified these themes in the 1980s; Paul Verhoeven's 1987 RoboCop depicts police officer Alex Murphy, mortally wounded and revived as a heavily armored cyborg enforcer, struggling to reclaim fragmented human memories against programmed directives, critiquing corporate control and dehumanization. The Terminator franchise, beginning with James Cameron's 1984 film, introduces the T-800 as an infiltration unit with living tissue over a titanium skeleton, designed for assassination but capable of reprogramming toward protective roles in later entries, reflecting anxieties over autonomous machines mimicking humanity. Television science fiction prominently featured collective cyborg entities with the Borg in Star Trek: The Next Generation, debuting in the 1989 episode "Q Who," where they appear as assimilated humanoids linked in a hive mind via cybernetic implants, pursuing technological perfection through forced integration and symbolizing the loss of individuality to uniformity. Anime and manga, such as Masamune Shirow's Ghost in the Shell (1989 manga, 1995 film adaptation), portray full-body prosthesis users like Major Motoko Kusanagi, whose brain resides in a synthetic shell, delving into philosophical questions of soul and consciousness in advanced cybernetic societies. These depictions often contrast heroic individual cyborgs retaining agency against dystopian collectives, mirroring real-world debates on augmentation's potential for empowerment versus erosion of autonomy, though fictional exaggerations like instantaneous assimilation or indestructible frames lack empirical basis in current biomechatronics.

Advocacy Movements and Real-World Practitioners

The Cyborg Foundation, established in 2010 by artists Neil Harbisson and Moon Ribas, serves as a primary advocacy organization for cyborg integration and rights. Its objectives include facilitating human augmentation through cybernetic implants, promoting the incorporation of technology into the human body, and defending legal protections for cyborgs against discrimination. The foundation has organized events, donated equipment for sensory extensions, and collaborated on projects to extend human perception, such as color-to-sound conversion devices. Neil Harbisson, born in 1982 and affected by achromatopsia—a condition causing complete color blindness—underwent surgery in 2004 to implant an "eyeborg" antenna in his skull, enabling him to perceive colors as audible frequencies via bone conduction. In 2013, the United Kingdom government recognized him as the world's first cyborg by issuing a passport photograph including the visible antenna, marking a milestone in official acknowledgment of cybernetic identity. Harbisson advocates for "transpecies rights," extending protections to individuals with non-human senses, and co-founded the Transpecies Society to represent such augmented beings. Moon Ribas, Harbisson's collaborator, implanted seismic sensors in her forearms in 2013, allowing her to physically feel earthquakes through vibrations calibrated to magnitude. She performs dances interpreting global seismic activity and uses the implants to advocate for environmental awareness intertwined with cyborg embodiment. Together, they promote cyborgism as a cultural movement, emphasizing voluntary augmentation for enhanced sensory capabilities rather than medical necessity alone. Broader advocacy efforts include calls for cyborg rights encompassing freedom to select implants without regulatory hindrance and protections from bias in employment or travel. The foundation's work has influenced discussions on human-machine boundaries, though empirical data on widespread adoption remains limited, with most practitioners operating as independent artists or biohackers rather than formalized collectives. These initiatives prioritize individual agency in technological self-modification, grounded in demonstrated functionality of implants like Harbisson's device, which has operated continuously for over two decades.
