摘要：

Displacement characteristics for a bimorph-type actuator, made with lead zinc niobate-based (PBZM) ceramics were investigated at temperatures from -20-degrees-C to 60-degree-C by driving the actuator with the bias driving method. Displacement was found to depend on both the temperature and the bias electric field; in particular, the temperature dependence of displacement can be improved by increasing the bias field strength. It was found that this displacement dependence is closely related to the relative dielectric constants of the ceramics.
