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 E1to E5are positioned on a top plate of the inner box-like structure. Four electrodes E6to E9are positioned on the four side surfaces of the inner box-like structure. Capacitance elements C1to C5are arranged by electrodes E1to E5and a top plate of the outer box-like structure and capacitance elements C6to C9are arranged by electrodes E6to E9and 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 C6and C7, a force Fy in the Y-axis direction is detected by means of the capacitance difference between C8and C9, a force Fz in the Z-axis direction is detected by means of the capacitance of C5, a moment My about the Y-axis is detected by means of the capacitance difference between C1and C2, and a moment Mx about the X-axis is detected by means of the capacitance difference between C3and C4.
