Abstract
The invention concerns a force sensor (10) comprising a first electrode (22) and a second electrode (24) made of conductive material, which are arranged spaced from each other on a first insulating support (12). The invention is characterized in that a contact element (26) is conductive material is placed opposite the two electrodes and some distance therefrom, said contact element t(26) being pressed against said electrodes (22, 24) when a force is exerted on the pressure sensor (10) and at least one of the electrodes (22, 24) is coated with a pressure sensitive material layer (28, 30).
