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.
