摘　　要：Piezoelectric actuators operating in piezoelectric-induced strain/stress or electromechanical res.onanceinduced vibration or wave-motion friction drive mechanism have shown many advantagesover traditional electromagnetic mot ors,especilly,when miniaturizing into millimeter-scale size,while magnetoelectric act uators operating in magnetostrictive mechanism are capable of piezo-dlectric self-sensing and remote operation under an applied magnetic field.This paper summarizesthe recent progresses in piezoelectric ceramic and single crystal materials based actuators andmicromotors,ferromagnetic/ferroeletric laminated magnetoelectric actuat ors,including rotary,linear,planner,and spherical motion actuators,and bending motion magnetoelectric actuators.Their driving mechanisms,operation propertics,and applications are also explained.
