Photostriction explainable by the superposition of the bulk photovoltaic effect and piezoelectricity has been investigated in the solid solution ceramics of (Pb, La)(Zr, Ti)O 3 . Using the optimum composition PLZT(3/52/48), we have fabricated a photodriven relay as a trial photostrictive actuator. Though the response is rather slow, we have observed primitive relay function controllable by the optical irradiation.
