Lead lanthanum zirconate titanate (PLZT) ceramic has draw significant attention for its promising application as a wireless photo-driven micro actuator. However, the residual photovoltage and photo-induced strain have a great influence on the response speed of photostrictive effect and prevent PLZT ceramic from using as a micro actuator, especially in high frequency dynamic field. In this paper, the coupled opto-piezo-thermo-elastic fields in PLZT ceramics were analyzed, based on which the mathematical equations of temperature, voltage and deformation during the light switched off phase were established. After that, the photostrictive static experiments were performed to validate the mathematical equations proposed.
