Abstract

A sequence of low force, high compliance, long extension, piezofilm-based sensors for a biofeedback system for self-monitoring of selected body motions. Flexible, large area, piezofim sensors are mounted on compliant but less flexible, larger area, backbone structures so as to distribute localized stress anomolies and produce a useful, coherent, signal voltage for realtime body motion monitoring. The sensors are used in combination with body appliances that permit suitable placement of the sensors proximate the body, in areas suitable for measuring body motion, such as twist, stretch and flexure. The sensors provide input signals to a small, self contained signal processing and feedback module that generates a limited sequence of stepped announcements indicating the amount of motion detected. Instant feedback is provided to the user in the form of audible tones, colored lights, or other means intended to provide periphery feedback without directly interferring with the intended motion.
