FORCE DETECTION DEVICE, ROBOT, AND MOVING OBJECT

摘要

A force detection device includes a charge output element that outputs charge in accordance with a received external force, a conversion and output circuit, having a first switching element and a first capacitor, which converts the charge into a voltage and outputs the voltage, a compensation signal output circuit, having a second switching element and a second capacitor, which outputs a compensation signal, and an external force detection circuit that detects an external force on the basis of the voltage which is output from the conversion and output circuit and the compensation signal which is output from the compensation signal output circuit. The capacitance of the second capacitor is smaller than the capacitance of the first capacitor.
