Abstract
Disclosed embodiments describe techniques for body part motion analysis. A stretch sensor is attached to a body part. Tape can be applied to the body part, and the stretch sensor can be attached to the tape using connectors, hooks, snaps, or Velcro™. The stretch sensor changes electrical characteristics as it stretches. A sensor coupled to the stretch sensor collects changes in electrical characteristics based on motion of the body part. A communication unit provides information from the sensor to a receiving unit. Motion of the body part is shown on a display. The displayed body part can be an animation and can be displayed in the context of an overall body. The stretch sensor is used for measuring body part motion. An inertial measurement unit provides augmented motion information. The stretch sensor senses muscle activities such as muscle activation and deformation and provides movement angle, force and torque evaluation.
