【Abstract】 Piezoelectric stack sensor/actuator (PSSA) is one of the most important elements of the piezoelectric intelligent active member, which is an electromechanical coupling system. The design principle of the PSSA is given firstly, and then the experiment and analysis of the dynamics and static characteristics for the sensor/actuator are carried out. The results of experiments have discovered that it possessed large displacement, better stability and repeatability and little hysteresis, which provide the developing bases for the piezoelectric intelligent active member.更多还原
