Abstract:
1. A force sensor configured for sensing an external force in at least two dimensions, wherein: the force sensor comprises an input part, an intermediate part, a base part-and a sensor element; the input part and the base part engage via the intermediate part; the input part has a first end-and a second end; the first end of the input part is configured for being subjected to the external force; the sensor element is located between the base part and the second end; the intermediate part engages the input part at a region of the input part at a position between the first end and the second end; the intermediate part is configured to undergo a deformation under combined control of the external force transmitted by the input part to the intermediate part and a reaction force applied by the base part to the intermediate part; the second end of the input part is configured for undergoing a change in at least one of: a position relative to the base part and an orientation relative to the base part in response to the deformation of the intermediate part; the change in at least one of the position relative to the base part and the orientation relative to the base part is representative of the external force; the sensor element is operative to sense the change and to supply an output signal indicative of the change.
