ABSTRACT:
An indication is given of a method, and simultaneously of an apparatus, for measuring pressures and forces acting on arbitrarily shaped bodies. Employed in this connection is a piezoelectric film, which is provided on both sides with a metal coating. The piezoelectric film is bonded onto the body, and a charge variation of the piezoelectric film is evaluated in an evaluation unit, and employed as measure for the force acting on the body, or for the pressure. The metal coating (5) is partially removed from one side of the piezoelectric film (2) to form individual sensors (3, 4). Each individual sensor (3, 4) is coupled to the evaluation unit (10) via an electrical connection (8, 9). The other side of the piezoelectric film (2) with the continuous metal coating (5) serves as electronic shield and is connected to earth (7). The charge variation of each individual sensor (3, 4) serves as measure for the local force or the local pressure.
