  • Patent number: 4555954
    Abstract: A tactile sensor (100) comprises a printed circuit board (102) having a plurality of spaced apart, electrically conductive foils (104) thereon, each coupled to a decoder (106) which selectively applies a voltage individually thereto. The foils are separated from each other by each of a plurality of upraised insulative portions (116) each comprised of a layer of photoresist material. An anisotropically electrically conductive rubber pad (107) having alternating electrically conductive and nonconductive strips (108, 110) overlies the substrate so that the conductive strips are supported in spaced relationship from the conductive foils by the upraised photoresist layers. Each conductive strip is coupled to a multiplexer (115). Upon the application of a force against the rubber sheet, the conductive strips are deformed into electrical contact with the conductive foils on the substrate.
