Abstract
An optical actuator includes pairs of stators disposed parallel to each other with a stipulated gap between them, a mover disposed moveably within the gap, and a number of photovoltaic devices. The photovoltaic device has device electrodes on either end in the direction of polarization, each connected to one of the pair of stators. The voltage generated by the photovoltaic effect of the device is utilized to generate force that displaces the mover with respect to the stators by means of electrostatic force arising from the voltage.
