Abstract
A piezoresistive force sensor generates a sensor signal dependent on an amount of a force acting on the force sensor in a force measuring direction. The force sensor has a first electrode, a second electrode and an elastically deformable resistance layer electrically connects the two electrodes. A resistance value of a total resistance of an electrically conductive path between the electrode via the resistance layer changes according to the amount of the acting force. By measuring a voltage between the electrodes or a current flows along the electrically conductive path, a sensor signal is detected as the amount of the acting force. The resistance layer contains electrically conductive first staple fibers and electrically non-conductive second staple fibers. A proportion of the first staple fibers relative to the total quantity of staple fibers is varied to adapt the force-resistance characteristic of the force sensor to the particular task.
