From large-scale industrial systems to components in consumer applications, mechatronics has woven itself into the very fabric of modern technology. Among the most important elements of mechatronic systems are electromagnetic sensors and electromechanical actuators. Cultivated over years of industrial and research experience, Sensors and Actuators in Mechatronics: Design and Applications builds a practical understanding of the features and functions of various electromagnetic and electromechanical devices necessary to meet specific industrial requirements. This work focuses on various components that receive less attention in the available literature, such as magnetic sensors, linear and latching solenoid actuators, stepper motors, rotary actuators, and other special magnetic devices including magnetic valves and heart pumps. Each chapter follows a consistent format, working from theory to design, applications, and numerical problems and solutions. Although the crux of the coverage is design and application, the author also discusses optimization and testing, introduces magnetic materials, and shares his enlightened perspective on the social and business aspects of developing world-class technologies. Examples from mainly the automotive industry illustrate the wide variety of mechatronic devices presented. Providing a complete picture from conception to completion, Sensors and Actuators in Mechatronics: Design and Applications places critical tools in the hands of any researcher or engineer seeking to develop innovative mechatronic systems.

Unlike other treatments of sensors or actuators, this book approaches the devices from the point of view of the fundamental coupling mechanism between the electrical and mechanical behaviour. The principles of operation of the solenoid are the same in both cases, and this book thus treats them together. It begins with a discussion of systems analysis as a tool for modelling transducers, before turning to a detailed discussion of transduction mechanisms. The whole is rounded off by an input/output analysis of transducers.

Microprocessors and computers used to be the main limiting element in most information processing systems. But thanks to the enonnous progress in the microelectronics industry, most information analysis tasks can be processed in real time. The data has to be acquired by the processor in some form and processed and used to produce some useful function in the real world.

I am profoundly convinced that notwithstanding the great progress made in solid-state magnetic sensors, they are as yet in their cloudless infancy, whereas there is still so much lying ahead in a world, unlimited in time and space ... Good Heavens! They are a whole Universe into themselves. So expounds the author in his preface to this second volume in the exciting new series, Handbook of Sensors and Actuators. The publication presents a balanced view of the overall progress made in the field, whilst summing up scientific achievements as the groundwork for further development. Readers will find, for the first time, collected in one book, detailed information regarding the physical mechanisms of the origin of magnetosensitivity, the geometry and design of devices, operating modes, basic parameters and methods for their determination, the incorporation of transducers in circuits and smart solutions, many varied applications and other problems relevant to all the current Hall sensors, magnetodiodes, magnetotransistors, carrier-domain magnetometers, SQUID's (Superconducting Quantum Interference Devices) and similar transducers of magnetic energy. Particular attention is devoted to semiconductor magnetosensitive sensors and their microelectronic versions since development rates in this area signify a dominant research trend for the future. Undoubtedly this book will become a vital reference tool for the ever widening circle of researchers and engineers interested in solid-state magnetosensors. It also makes a fundamental contribution to the handbook series as a whole.

This undergraduate textbook introduces students to the principles and applications of sensors and actuators, crossing multiple disciplines including aerospace, biomedical, chemical, civil, electrical and mechanical engineering. An excellent professional reference for those needing to learn the basics of sensing and actuation, this book is a good choice for industry training seminars. This book "connects the dots" of theory and circuits basics into meaningful systems and real-world applications. Designed to introduce students and practitioners to the principles and applications of sensors and actuators, this book discusses processing hardware and the embedded systems software that connects them. It is written based on the theory that a system is made of three components: Inputs, Outputs and Processors and looks at sensors and actuators based on the broad area of detection. Important coverage is given to interfacing (the processes and mechanisms between the sensor and actuator) that make a system work reliably and accurately. The material is presented with clear explanations, examples and diagrams, making it ideal for students and practitioners concerned with systems engineering in a broad variety of fields, especially those that depend on sensors for detecting pre-determined conditions.
