Abstract
A rectifier circuit rectifies power generation voltage of a piezoelectric element to generate DC voltage and supplies the power generation voltage to a load. Upon termination of a process started upon reception of the DC voltage supplied from the rectifier circuit, the load sets a discharge switch to a conduction state using an output port signal. The electric charge remaining in the piezoelectric element is reset to zero by the discharge switch.
