Abstract

A capacitive sensor system is adapted for use as a wearable sensor and is capable of measuring the muscle activity of a user. The sensor system monitors the change in distance between an electrode and the user's skin, where the change is caused by the changing muscle cross-sectional area or muscle bulging. A musculoskeletal model is used to validate the capacitance measurement with the muscle cross-sectional area from gold-standard marker-based motion capture along with gold-standard measurements of muscle excitation, and muscle contraction force. The sensor can be used in real-world settings to assist with gait rehabilitation, among other uses.
