Flexible film sensor system for monitoring body motion
First Claim
1. A method for self teaching improvements in a selected repetitive kinetic body motion corprising the steps ofusing at least one body motion transducer applied to a preselecled location on the user'"'"'s body corresponding to said selected repetitive kinetic body motion, dividing the full range of output of said transducer into a limited set of incremental ranges of body motion, associating each said incremental range with a different color from a limited set of colors, repetitively sensing the body position with said transducer throughout a full cycle of a said body motion, determining in which of said incremental ranges is the current body position, generating a visual feedback signal of the associated said color in real time within the user'"'"'s view.

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.
