  We demonstrate here a proof-of-concept experiment that microelectromechanical
systems (MEMS) can be actuated using photoelectrowetting. In order to
demonstrate this, a 30 \mu m thick aluminum cantilever is actuated using an
ordinary white light source. A deflection of 56 \mu m is observed using a light
irradiance equal to \approx 1000 W m-2 at a bias of 7 V. The deflection of the
cantilever relies on the recently observed photoelectrowetting effect [Sci.
Rep.1, 184 (2011)]. Such "actuation at a distance" could be useful for optical
addressing and control of autonomous wireless sensors, MEMS and microsystems.
