Abstract

The photo-induced strain in transparent lead lanthanum zirconate titanate (PLZT) materials is due to a process of superposition of photovoltaic and converse piezoelectric effects. The photovoltaic effect in PLZT materials is observed only in the direction of spontaneous polarization of ferroelectric materials. In this paper, electrical and mechanical performance of PLZT ceramics polarized in 0-1 or 0-3 direction are investigated, and PLZT actuators and sensors with the 0-3 polarization are studied. For multilayer PLZT actuators, presented also are the formulas for the calculation of energy release rates due to debonding.
