Abstract

See full text

An actuator includes an electrolyte membrane, first and second driving electrodes that are disposed on the opposite surfaces and that give a potential difference to the electrolyte membrane, a sensor that is formed on the electrolyte membrane and that detects a force acting on the electrolyte membrane, and a driving control circuit that supplies a drive voltage to the first and second driving electrodes on the basis of an instruction signal and a detection output of the sensor. The driving control circuit applies a PWM drive voltage with a duty ratio corresponding to a difference between the instruction signal and the detection output of the sensor across the first driving electrode and the second driving electrode.
