An important aim of the presented book is the explanation of the application of piezoelectric materials such as piezoceramics within the wide field of electromechanical actuators and sensor technology. The reader should be presented the physical and mechanical properties of piezoceramics in a distinct way. In a next step, the reader is introduced into the mechanical description of the static behavior of piezoelectric multilayer beam bending actuators. The description of the dynamic behavior of piezoelectric multilayered bending actuators is effected on the basis of Lagrange‘s formalism and Hamilton‘s principle. The achieved insights are used for the systematic development of the electromechanical circuit representation within the scope of the network theory for any design of piezoelectric bending actuators. The applications of piezoelectric multilayer beam bending actuators can be extended by means of special displacement sensors allowing for the compensation of effects such as hysteresis, creep and drift being typical for piezoelectric actuators. Within the scope of the presented book, two different sensor-actuator-systems are presented being based on an integrated capacitive and inductive displacement sensor, respectively. Analytical simulations of the static and dynamic behavior are compared to real measurement results of a specially developed piezoelectric multilayer beam bender. Here, the suitability of the developed theoretical aspects is shown in an outstanding way.

Electromechanical systems consisting of electrical, mechanical and acoustic subsystems are of special importance in various technical fields, e.g. precision device engineering, sensor and actuator technology, electroacoustics and medical engineering. Based on a circuit-oriented representation, providing readers with a descriptive engineering design method for these systems is the goal of this textbook. It offers an easy and fast introduction to mechanical, acoustic, fluid, thermal and hydraulic problems through the application of circuit-oriented basic knowledge. The network description methodology, presented in detail, is extended to finite network elements and combined with the finite element method (FEM): the combination of the advantages of both description methods results in novel approaches, especially in the higher frequency range. The book offers numerous current examples of both the design of sensors and actuators and that of direct coupled sensor-actuator systems. The appendix provides more extensive fundamentals for signal description, as well as a compilation of important material characteristics. The textbook is suitable both for graduate students and for engineers working in the fields of electrical engineering, information technology, mechatronics, microtechnology, and mechanical and medical engineering.

Die vielfältigen industriellen Einsatzmöglichkeiten von piezoelektrischen Biegewandlern als Aktoren und hochpräzise Positioniersysteme erfordern eine an die jeweilige Aufgabe angepasste Leistungsfähigkeit. Dies setzt voraus, dass bereits in der Entwurfs- und Entwicklungsphase das statische und dynamische Verhalten solcher Aktor-Strukturen in der jeweiligen Anwendung vorhergesagt werden kann. Die geometrischen Abmessungen der einzelnen aktiven und passiven Schichten, ihre Abfolge im Schichtsystem und ihre elasto- und elektromechanischen Eigenschaften sind dabei Schlüsselfaktoren. Dieses Buch konzentriert sich auf die analytische Beschreibung des statischen und dynamischen Verhaltens von piezoelektrischen Mehrschicht-Biegewandlern. Es soll Studierenden der Natur- und Ingenieurwissenschaften, insbesondere der Physik, der Mikro- und Feinwerktechnik, der Mess- und Sensortechnik, der Mechatronik und Automatisierungstechnik sowie Ingenieur:innen und Wissenschaftler:innen in der Praxis ein solides technisches Werkzeug für den Entwurf von piezokeramischen Biegewandlern an die Hand geben. Die Vorteile der analytischen Beschreibung werden anhand realer Messungen an einem Monomorph in Multilayer-Technologie demonstriert. Die Anforderungen an das Verständnis des Materials beschränken sich auf Grundkenntnisse der ein- und mehrdimensionalen Analysis sowie der elementaren Newtonschen Mechanik, der technischen Mechanik und der Elektrizitätslehre.
