Piezoelectric Bending Transducers

The wide range of industrial applications for piezoelectric bending transducers as actuators and high-precision positioning systems requires their performance to be adapted to the respective task. This presupposes that it is already possible to predict the static and dynamic behaviour of such actuator structures in the respective application during the design and development phase. The geometric dimensions of the individual active and passive layers, their sequence in the layer system and their elasto- and electromechanical properties are key factors here. This book focuses on the analytical description of the static and dynamic behaviour of piezoelectric multilayer bending transducers. It is intended to provide students of natural sciences and engineering as well as engineers and scientists in practice with a solid engineering tool for the design of piezoceramic bending transducers. The benefits of the analytical description obtained are demonstrated based on real measurements on a monomorph in multilayer technology. The requirements for understanding the material are limited to basic knowledge of one- and multidimensional analysis as well as elementary Newtonian mechanics, technical mechanics and electricity.
