Sensor device, in particular for a prosthesis, and prosthesis having such a sensor device
First Claim
1. Sensor device at the connecting point between two parts (4, 5), in particular in a prosthesis, having a ring-shaped outer member (16) of closed construction for connecting the two parts (4, 5) and an inner member (21, 22, 22′
- ) connecting two opposite inner sides (17a, 17b) of the outer member having a sensor element (31) for measuring the force acting in the direction of the connecting axis between the two parts (4, 5).

Abstract
A sensor device (15) for a prosthesis, in particular for a leg prosthesis, is provided for measuring forces acting on the prosthesis, having a ring-shaped outer member (16) of closed construction and an inner member (21, 22) connecting two opposite inner sides (17a, 17b) of the outer member having a sensor element (31) for measuring the force acting in the direction of the connecting axis. The outer member deforms under the action of a bending moment while the inner member (21) feels only the axial force acting in the direction of its connecting axis. By this means measurement of the axial force unaffected by bending moments is possible. Furthermore, the sensor device is able to transmit loads.

- 15. Sensor device for measuring mechanical forces having a sensor section (22) containing a force sensor (31) for measuring a force (Fax) acting on the sensor section (22) in a first direction and a flexural relief section (16, 23) connected to the sensor section (22) which is constructed in such a way that under the action of a force acting in a second direction it is deformed in such a way that the sensor section (22) remains substantially unaffected.
