<title>Piezoelectric actuator technology</title>

Abstract

Piezoelectric actuator technology is reviewed, and the performance of current state-of-the-art piezoelectric actuator devices estimated. Comparisons between actuator configurations show a wide range of available force and displacement performance. General design guidelines for the selection and use of piezoelectric actuators for active vibration and control applications are given. Examples of state-of-the-art actuator devices are given for each actuator case.
