Electroacoustic transducers (EAT) are devices, which transform electric energy to energy of acoustic fluctuations. Principles of action, design of transducers for work in air and water as well as for non-destructive control are described in the book. New technologies of designing EAT, not only expanding designing possibilities, are described. They also allow to create transducers with improved characteristics. In particular, methods to increase target capacity (sound pressure), decrease working (resonant) frequency of transducers and expand frequencies of projectors and sound receivers are developed. Methods and control units of transducers in batch production of transducers are described, too.

This book presents the latest and complete information about various types of piezosensors. A sensor is a converter of the measured physical size to an electric signal. Piezoelectric transducers and sensors are based on piezoelectric effects. They have proven to be versatile tools for the measurement of various processes. They are used for quality assurance, process control and for research and development in many different industries. In each area of application specific requirements to the parameters of transducers and sensors are developed. The book presents the fundamentals, technical design and details and practical applications. Methods to design piezosensors are described, allowing to create sensors with unique properties. New methods to measure physical sizes and new constructions of sensors including large area of piezosensors are described in this book. This book is written for specialists in transforming hydroacoustics, non-destructive control, measuring technique, sensors development for automatic control and also for graduate students.

Explores State-of-the-Art Work from the World’s Foremost Scientists, Engineers, Educators, and Practitioners in the Field Why use smart materials? Since most smart materials do not add mass, engineers can endow structures with built-in responses to a myriad of contingencies. In their various forms, these materials can adapt to their environments by changing characteristics and can provide information about structural and environmental changes. A single source on numerous aspects of intelligent materials Smart Materials focuses on many types of novel materials, including ceramics, hybrid composites, shape memory alloys, chitosan-based gels, adhesives, oxides, polymers, flip-chip technology, magnetorheological fluids, electrorheological materials, nanotubes, and sensors. It highlights the interdisciplinary nature of these materials by showing how they can be used in scores of areas, such as drug delivery systems, health monitoring, fiber optics, nanoscale engineering, vibration control, and molecular imprinting. Gain insight from leading experts who specialize in smart materials technology With over fifty years of experience working and teaching in this field, the editor has compiled numerous insightful contributions from an extensive group of leading experts. In this volume, they share their expertise and explore the innovative progress that has occurred in smart material products, components, systems, and structures.

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.

Elektromechanische Systeme, bestehend aus wechselwirkenden elektrischen, mechanischen und akustischen Teilsystemen gewinnen im Präzisionsgerätebau, in der Sensor- und Aktortechnik, der Elektroakustik sowie in der Medizintechnik eine immer größere Bedeutung. Durch die Anwendung der Silizium-Mikromechanik nimmt ihre Verbreitung in Form von integrierten Mikrosystemen weiter zu. Die Vermittlung einer anschaulichen, ingenieurmäßigen Entwurfsmethode für elektromechanische Systeme auf der Grundlage einer schaltungstechnischen Darstellung ist das Hauptanliegen des Lehrbuches. Es ermöglicht dem Studierenden sowie dem in der Praxis tätigen Elektroingenieur einen raschen Einstieg in die für ihn zunächst fremden mechanischen, akustischen, hydraulischen und thermischen Problemstellungen durch die Anwendung seines schaltungstechnischen Grundwissens. Aber auch umgekehrt eröffnet es dem Nicht-Elektrotechniker den Zugang zu den übersichtlichen und komfortablen Methoden der Netzwerktheorie.
