A pressure sensor, e.g. for being arranged in the sole structure of an article of footwear, for measuring a pressure exerted by the wearer's foot. The pressure sensor has one or more pressure-sensing cells. Each cell has a first flexible carrier film and a second flexible carrier film, the first and second carrier films being attached to one another by a spacer film having an opening, a plurality of first electrodes arranged on the first carrier film and a plurality of second electrodes arranged on the second carrier film. The plurality of first electrodes has a first group of electrodes and a second group of electrodes. The first and second groups of electrodes are arranged so as to interdigitate with delimiting gaps there between. One or more electrically insulating overprints are arranged on the first carrier film so as to cover the gaps.

Pressure sensor, e.g. in sole for an article of footwear

Disclosed is a sensor mat for determining a seat occupation situation of a vehicle seat. Said sensor mat comprises a plurality of sensor cells which can be allocated to a sitting area of the vehicle seat and are configured and interconnected in such a way that an output signal of the sensor mat varies in accordance with the seat occupation situation. At least one first sensor cell and a second sensor cell are interconnected to a pair of sensor cells such that the output signal of the sensor mat exceeds or lies below a predefined threshold value independently of the triggering state of the other sensor cells when the first and the second sensor cell are triggered simultaneously.

Sensor mat comprising two switching levels

A film-type pressure sensor includes a carrier structure including a first carrier film, a second carrier film and a spacer film arranged between the first and second carrier films, where one or more pressure-sensing cells are disposed in the carrier structure, each of which includes an electrode arrangement for producing an impedance change in response to a compressive force, an electrical interface is provided for mechanically and electrically connecting the pressure sensor to an evaluation circuit, where some terminals of the interface are connected with the electrode arrangements of the cells so as to allow them to be read out, such that one or more electrical components interconnect at least two of the terminals in pairs so as to form a combination of terminal pair impedances that represents coded information relating to the pressure sensor.
