Photostriction in ferroelectrics arises from a superimposed phenomenon of the photovoltaic and inverse piezoelectric effects. This paper reviews the recent developments in materials and their device applications: ion doping effect is described in (Pb, La)(Zr, Ti)03 based ceramics firstly to iraprove the response speed, then the drive/control methods (polarized light method and dual beam method) are presented, finally photo-driven relays, micro Walking machines and photoacoustic devices are introduced. The devices based on a biraorph structure were designed to start moving by the irradiation without any external electric circuit.
