Patent ID: 8904876

Claim:
A pressure sensitive sensor for producing an electrical output signal proportional to pressure exerted on said sensor, said sensor comprising; a. a first, electrically conductive base lamination which has an outer planar surface and an inner electrically conductive planar surface, b. a second, electrically conductive cover lamination which has an outer planar surface and an inner electrically conductive planar surface which confronts said inner conductive surface of said base lamination, and c. a pad positioned between said first and second laminations, said pad having a first outer surface in contact with said inner conductive surface of said base lamination and a second outer surface in contact with said inner surface of said cover lamination, said pad having an electrical property which is proportional to a force or pressure couple exerted normally on outer surfaces of said base lamination and said cover lamination sufficient to decrease spacing between said inner conductive surfaces of said first and second laminations.
