High-Speed Motion Capture

image12

High-speed video cameras with capture rates up to 38,500 fps (1057 fps at full resolution) are used to record dynamic movements.

Inertial Measurement Units

image14

Low profile, flexible and waterproof inertial measurement units (IMU) are attached to the body with adhesive to measure motion without the need for video cameras.

GPS

image16

Miniature global positioning system (GPS) sensor is used to identify an individual's position and the change in position to track their outdoor motion path.

EMG

image17

Wireless surface electrodes are placed over muscles to provide a relative measure of electromyographic (EMG) activation.

Wearable Sensors

Pilot work exploring embedded wearable sensors and biomechanical models using Xsens inertial measurement units (IMUs).  The orientation of the body segments are measured with several miniature sensors for movement analysis.
