Xsens Technologies B.V. (or Xsens) is a supplier of 3D motion capture products and inertial sensors based upon miniature MEMS inertial sensor technology.

The company has created intellectual property in the field of multi-sensor data fusion algorithms, combining inertial sensors with aiding technologies such as GPS, Motion capture and biomechanical modeling. Xsens is the product brand for their motion capture and inertial sensor products. Xsens is a brand of Movella, a company formed by combining mCube, Xsens, and Kinduct. Movella digitizes movement from humans and machines.

Xsens has offices in Enschede (headquarter, Netherlands), Los Angeles, Bangalore, Shanghai, and Halifax.

The company was founded in 2000 by Casper Peeters and Per Slycke, both University of Twente graduates. Following work in measurement of the performance of athletes, they specialized in sensor technologies and sensor fusion algorithms. The company developed Inertial measurement units or AHRS (MTi-series and MTx) and human movement measurement systems (a completely wireless system MTw Awinda, the successor of the Xbus Kit).

In 2007 Xsens introduced an inertial motion capture system called "Moven" (renamed to Xsens MVN in 2009).

In 2008, Xsens acquired Utellus, a spin-off from telecom company Ericsson's EuroLab, specializing in applications of ultra wide band RF technology.

In 2009 Xsens introduced the MVN BIOMECH system, a motion capture system for 3D human kinematics used in fields such as ergonomics, sports science and rehabilitation.

In 2014 Xsens was acquired by Fairchild Semiconductor, and became part of ON Semiconductor in 2016.
