Abstract:
Force sensor comprising:two electrodes made of a conducting material, said two electrodes being arranged on a first insulating support in such a way that they are separated from each other, each of said two electrodes being coated with a layer of pressure-sensitive material, the two layers of pressure-sensitive material being electrically insulated from each other, and a contact element made of a conducting material, said contact element being arranged at a certain distance from said two electrodes, said contact element being pressed against said electrodes when a force is exerted on the force sensor, wherein each electrode comprises a conductor arranged at a periphery of an active zone of the sensor, and wherein said layer of pressure-sensitive material covering each electrode covers the conductor of the electrode and extends from said conductor towards the interior of the active zone, the two pressure-sensitive layers being separated by an interstice interposed centrally in the active zone.
