FORCE DETECTOR AND FORCE DETECTION SYSTEM

A force detector (1) includes a layered structure including a first layer (2) and a second layer (3). The first layer includes a detection face (M) configured to receive a force to be detected and the second layer is disposed on a face opposite to the detection face. A Young's modulus of the first layer (2) is different from a Young's modulus of the second layer (3). The force detector further includes a stress generator (4) formed in the layered structure and configured to receive the force acting in a tangential direction of the detection face and generate a stress with a distribution that is asymmetric with respect to a normal direction of the detection face around the stress generator. The force detector further includes a plurality of sensors (5) disposed around the stress generator.
