Inertial Measurement Unit (IMU)

T-Sens wireless motion sensors integrate a 3-axis accelerometer, a 3-axis gyroscope, and a 3-axis magnetometer with powerful fusion algorithms. Measurements are extremely robust overtime against vibrations, disturbances in the magnetic field and can be recorded in challenging environments


IMU, or Inertial Measurement Unit, is a device that measures and reports a body’s specific force, angular rate, and orientation of the body. These sensors have an integrated 3-axis accelerometer, a 3-axis gyroscope, and a 3-axis magnetometer, with powerful fusion algorithms that provide precise measurements of human body motion. These wireless sensors enable motion capture in real-world environments, without the need for external capture cameras. The data is then streamed into CAPTIV, a software that enables accurate displays and analysis of human body motion (angles on joints, angular speed and angular acceleration) with multiple analysis and reporting capabilities. 


  • Sensors with easy and unobtrusive fixation system
  • Unchallenged robustness to magnetic disturbances
  • Joint colorization
  • Conversion in angles, angular speed and angular acceleration
  • Customizable thresholds
  • Possibility of recording in mobile setups with no restriction of range or distance
  • Real-time display and recording
  • Real-time streaming to customer or third-party
  • Raw data available

CAPTIV Software

CAPTIV is a flexible and scalable software and hardware solution enabling the synchronous recording, display, and analysis of multiple data sources and inputs. Up to 32 wireless sensors can be recorded and synchronized with 3rd party devices such as eye-trackers, dry EEG systems, and more. CAPTIV also has multiple analysis tools and reports, such as heart rate, joint angles, static and dynamic EMG, gait, arousal, and more. All of the data can be export into standard formats, or automatically integrated into reports.
