Abstract
A sensor device for torque measurement includes a substrate, a first conductor track, and a second conductor track. The first conductor track and the second conductor track are arranged on the substrate, and each of the first conductor track and the second conductor track includes at least one region having meander-shaped structures. The structures of the first conductor track and the structures of the second conductor track are each continuously connected to each other via connecting sections. The structures make it possible to determine the torque load on the substrate. The structures of the first conductor track and the structures of the second conductor track extend in an alternating manner along a curve.
Claims22
A sensor device for torque measurement, comprising:
- a substrate;
- a first conductor track arranged on the substrate and including meander-shaped structures that are connected to each other via connecting sections;
- and
- a second conductor track arranged on the substrate and including meander-shaped structures that are connected to each other via connecting sections;
- wherein the sensor device is adapted to determine a torque load of the substrate;
- wherein the structures of the first conductor track and the structures of the second conductor track are arranged alternatingly along a curve;
- and
- wherein the curve is arranged on an outgoing path, from an origin in a circumferential direction, without interruption and at least in sections along a first circular line and is arranged on a returning path, to the origin in the circumferential direction, at least in sections along a second circular line.
A sensor device for torque measurement, comprising:
- a substrate;
- a first conductor track arranged on the substrate and including zig-zag-shaped structures that are connected to each other via connecting sections;
- and
- a second conductor track arranged on the substrate and including zig-zag-shaped structures that are connected to each other via connecting sections;
- wherein the sensor device is adapted to determine a torque load of the substrate;
- wherein the structures of the first conductor track and the structures of the second conductor track are arranged alternatingly along a curve;
- and
- wherein the curve is arranged on an outgoing path, from an origin in a circumferential direction, without interruption and at least in sections along a first circular line and is arranged on a returning path, to the origin in the circumferential direction, at least in sections along a second circular line.
