ABSTRACT:
There is disclosed an applied technology of an elementary sensor for sensing a force comprising a transducer for transforming a mechanical deformation to an electric signal, and a first strain generative body (20) including a supporting portion (21) and a working portion (23) connected to the transducer so as to allow the transducer to produce a mechanical deformation on the basis of a displacement relative to the supporting portion of the working portion. By further adding a second strain generative body (30) including a fixed portion (31) fixed at least with respect to the direction of a force to be detected, and a displacement portion (33) connected to the working portion of the first strain generative body, wherein the displacement portion is constructed to produce a displacement based on a given external force relative to the fixed portion to transmit the displacement thus produced to the working portion of the first strain generative body, a force detector applicable to a wide variety of measurement ranges can be realized. Moreover, by allowing the displacement portion to be elongated, a detector suitable for measurement of both force and moment can be provided. In addition, an embodiment to connect stylus (306) to the elementary sensor to apply it to a contact detector, and an embodiment to affix the elementary sensor at the hand of a robot to apply it to a gripper for robot are disclosed.
