摘要: A capacitive sensor system including a sensing plate, an amplifier, and switching circuit is described. The plate capacitively coupled to body surface. change in the electric potential on surface generates field that induces of plate. includes node positioned for generating input signal from field. not contact with amplifier receives at port, amplifies output port. connected port reference voltage. non-continuously closes shunting path voltage reset node.
