Abstract
The force sensor according to the invention has a support, a first pressure-sensitive layer, arranged on a first side of the support and connected to a first conductor track, a first force-introduction part with a first contact area which is bounded by edges and is connected to the first pressure-sensitive layer in a first bearing region. A second pressure-sensitive layer, connected to a second conductor track, is arranged on a second side of the support, and a second force-introduction part with a second contact surface bounded by edges is connected to the second pressure-sensitive layer in a second bearing region.
Claims11
A force sensor, containing
- a) a support (4),
- b) a first pressure-sensitive layer (1a), which is arranged on a first side of the support (4) and is connected to a first conductor track (3a),
- c) a first force-introduction part (5a) with a first contact area which is bounded by edges and is directly connected to the first pressure-sensitive layer (1a) in a first bearing region (2a),
- wherein a second pressure-sensitive layer (1b), which is connected to a second conductor track (3b), is arranged on a second side of the support (4) opposite the first side of the support (4), and a second force-introduction part (5b) with a second contact surface bounded by edges is directly connected to the second pressure-sensitive layer (1b) in a second bearing region (2b), wherein the pressure-sensitive layers (1a, b) are composed of a piezoelectric, piezoresistive material or a semiconductor material.
