Sensor device, in particular for a prosthesis, and prosthesis having such a sensor device
First Claim
1. A sensor device constructed to be located between two parts having a connecting axis between the two parts, the sensor device having a closed, ring-shaped outer member for connecting the two parts, the ring-shaped member having first and second opposing inner sides;
- an inner member connecting only the first and second opposing inner sides of the outer member; and
a first sensor element located on the inner web member for measuring the force acting in the direction of the connecting axis between the two parts.

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. A sensor device for measuring mechanical forces, the sensor device comprising:
-
a sensor section, a force sensor located on the sensor section for measuring a first force (Fax) acting on the sensor section in a first direction; and
a flexural relief section connected to the sensor section, the flexural section being structured and arranged in such a manner that, under the action of a second force acting in a second direction, the flexural relief section is deformed in such a manner that the sensor section remains substantially unaffected by the second force. - View Dependent Claims (16, 17, 18)
