Piezoelectric Bending Transducers: The Physics of Their Static and Dynamic Behaviour A Textbook About Indispensable Actuators in Microtechnology, Mechatronics Medical Technology

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. The wide range of industrial applications for piezoelectric bending transducers as actuators and high-precision positioning systems require a performance that is adapted to the respective task. The geometric dimensions of individual active and passive layers, their sequence in the layer system and their elastomechanical 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 and engineering sciences, in particular physics, micro- and precision engineering, measurement and sensor technology, mechatronics and automation technology, as well as engineers and scientists in practice with a solid technical tool for the design of piezoceramic bending transducers. The requirements for understanding the material are limited to basic knowledge of one- and multi-dimensional analysis as well as elementary Newtonian mechanics, technical mechanics and electricity. The Author Rüdiger G. Ballas studied Microsystems Engineering at Kaiserslautern University of Applied Sciences and completed his doctorate at TU Darmstadt in the field of piezoelectric bending transducers. He holds the professorship for Electrical Engineering at the Wilhelm Büchner University of Applied Sciences in Darmstadt and has won several national and international awards in the field of piezoelectric materials and their applications. His research focuses in particular on piezoelectric materials, sensors and actuators as well as piezoelectric energy generation and (micro-)electromechanical systems (MEMS). 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.
