ABSTRACT:
A thin film force sensor designed to sense application of a force over a wide area. In one embodiment, a large area sensing cell is provided that comprises a first planar electrode configured as a perimetric conductive portion circumscribing at least one additional perimetric conductive portion, with the conductive portions electrically connected together through at least one conductive path and a second planar electrode configured as a perimetric conductive portion circumscribing at least one additional perimetric conductive portion, with the conductive portions electrically connected together through at least one conductive path. The second planar electrode confronts the first planar electrode, with a pressure sensitive resistive material interposed between the first planar electrode and the second planar electrode. The conductive portions of the first planar electrode are substantially coextensive with the conductive portions of the second planar electrode, such that application of a broad force applying means anywhere within the perimeter of the perimetric conductive portion is electrically discernible, and a conductive lead extends from each electrode for providing an electrical termination for the electrode.
