Abstract: A foil-type pressure sensor includes a first carrier foil and a second carrier foil arranged at a certain distance from each other by means of a spacer, the spacer comprising at least one recess defining an active area of the pressure sensor. At least two electrodes are arranged in the active area of the pressure sensor between said first and second carrier foils in such a way that, in response to a pressure acting on the active area of the pressure sensor, the first and second carrier foils are pressed together against the reaction force of the elastic carrier foils and an electrical contact is established between the at least two electrodes. According to the invention, at least one of the carrier foils includes a multi-layered configuration with at least two layers of different materials.

Abstract: An impact sensor system with at least one foil-type switching element having a plurality of active areas including at least a first a second carrier foil arranged at a certain distance by at least one first spacer.The spacer has a plurality of recesses defining at least a first part of the active areas. In each active area, at least two electrode structures are arranged between the first and second carrier foils in such way that in response to a force acting on the active area, the first and second carrier foils are pressed together against the reaction force of the carrier foils and that, above a predetermined activation threshold force, an electrical contact is established between the electrode structures. The foil-type switching element is configured such that the activation threshold forces of a first group of said the active areas and a second group of active areas is different.
