Abstract

Recent developments in the areas of piezoelectric and electrostrictive actuators are reviewed; historical and theoretical background, recently-developed materials, applications, and future problems are discussed. Materials such as lead zirconate titanate (PZT)-based and lead magnesium niobate (PMN)-based ceramics reveal excellent actuator characteristics, especially by using wet-chemical preparation technique. Electrostrictive actuators are largely divided into three categories; servo displacement transducers, pulse-driven motors, and ultrasonic motors. More than 20 practical applications are now under study, including deformable mirrors, cutting error compensation mechanisms, impact dot-matrix printers and surface-wave-type piezomotors. The remaining problem is reliability/durability of the actuators.
