Abstract

In force sensing apparatus for a driving device which employs a shape memory alloy, note is taken of the fact that a force to be generated by the shape memory alloy varies depending upon the temperature or resistance and the displacement of the shape memory alloy, and force information on an output of the driving device is detected on the basis of information of the temperature or resistance and the displacment of the shape memory alloy.
