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 ( 17 a, 17 b) 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.
