ABSTRACT:
A transducer system comprising, a multiple capacitive transducer having a flexible dielectric sheet of elastic nonconductive material, a first plate of flexible conductive material defining a region located adjacent a first surface of the sheet, and a plurality of second plates of flexible conductive material located adjacent a second surface of the sheet, with the second plates defining areas aligned with the region of the first plate. The system separately forms signals responsive to the capacitance between the first and second plates.
