Abstract
Forces and moments are detected in a distinguished manner by a simple structure. An outer box-like structure formed of a metal is set on top of an insulating substrate and an insulating inner box-like structure is contained in the interior. Five electrodes Eto Eare positioned on a top plate of the inner box-like structure. Four electrodes Eto Eare positioned on the four side surfaces of the inner box-like structure. Capacitance elements Cto Care arranged by electrodes Eto Eand a top plate of the outer box-like structure and capacitance elements Cto Care arranged by electrodes Eto Eand side plates of the outer box-like structure. A force Fx in the X-axis direction is detected by means of the capacitance difference between Cand C, a force Fy in the Y-axis direction is detected by means of the capacitance difference between Cand C, a force Fz in the Z-axis direction is detected by means of the capacitance of C, a moment My about the Y-axis is detected by means of the capacitance difference between Cand C, and a moment Mx about the X-axis is detected by means of the capacitance difference between Cand C.
