ABSTRACT:
A force sensing means comprising capacitor plates in the form of metallic cloth bonded to a compressible dielectric made from a foamed elastomeric material. An incompressible layer of insulating material may be formed over one or both of the capacitor plates and additional capacitor plate or plates may be provided bonded to the insulating layer to shield the capacitor plates bonded to the compressible dielectric. The metallic cloth strips forming the capacitor plates may be formed in the form of strips running crosswise on opposite sides of the dielectric to provide a matrix of force sensing means. The warp and weft threads of the metallic cloth are arranged so that neither is perpendicular or parallel to the longitudinal direction of the strip.
