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.

Microactuators provides a comprehensive coverage of the emerging topic of microactuators that has attracted much attention in recent years. Largely owing to the microfabrication methods used in the microelectrics industry, microactuators are being developed at a very fast rate. Although there have been some excellent review articles covering parts of this important field, until now there has not been a single book devoted to its comprehensive coverage. Microactuators covers the fundamentals of actuation in a textbook manner and it exposes the reader to some research examples. In combining fundamentals with the latest reported actuators, this book distinguishes itself from other monographs or textbooks. The main intended audiences of Microactuators are academic and industrial researchers and graduate students interested in initiating projects in microactuators. It can also be used as a textbook for a senior/graduate level course in the general area of sensors and actuators.

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.

When choosing the technology options to develop a wireless sensor network (WSN), it is vital that their performance levels can be assessed for the type of application intended. This book describes the different technology options – MAC protocols, routing protocols, localisation and data fusion techniques – and provides the means to numerically measure their performance, whether by simulation, mathematical models or experimental test beds. Case studies, based on the authors’ direct experience of implementing wireless sensor networks, describe the design methodology and the type of measurements used, together with samples of the performance measurements attained. The book will enable you to answer vital questions such as: * How long will my network remain alive given the amount of sensing required of it? * For how long should I set the sleeping state of my motes? * How many sensors should I distribute to meet the expected requirements of the application? * What type of throughput should I expect as a function of the number of nodes deployed and the radio interface chosen (whether it be Bluetooth or Zigbee)? * How is the Packet Error Rate of my Zigbee motes affected by the selection of adjacent frequency sub bands in the ISM 2.4GHz band? * How is the localisation precision dependant on the number of nodes deployed in a corridor? Communications and signal processing engineers, researchers and graduate students working in wireless sensor networks will find this book an invaluable practical guide to this important technology. "This book gives a proper balance between theory and application; it is a book for those R&D engineers that want to appreciate both why, how and in which domains Wireless Sensor Networks can be best applied." - Fabio Bellifemine, Telecom Italia "This book is a thorough and accessible exposition on wireless sensor networks with a good balance between theory and practice; it is valuable for both students and practicing engineers, and is an essential addition for engineering libraries." - Professor Moe Win, Associate Professor at the Laboratory for Information and Decision Systems (LIDS), Massachusetts Institute of Technology *Only book to examine wireless sensor network technologies and assess their performance capabilities against possible applications *Enables the engineer to choose the technology that will give the best performance for the intended application *Case studies, based on the authors’ direct experience of implementing wireless sensor networks, describe the design methodology and the type of measurements used, together with samples of the performance measurements attained

Like the previous editions also the third edition of this book combines the detailed physical modeling of mechatronic systems and their precise numerical simulation using the Finite Element (FE) method. Thereby, the basic chapter concerning the Finite Element (FE) method is enhanced, provides now also a description of higher order finite elements (both for nodal and edge finite elements) and a detailed discussion of non-conforming mesh techniques. The author enhances and improves many discussions on principles and methods. In particular, more emphasis is put on the description of single fields by adding the flow field. Corresponding to these field, the book is augmented with the new chapter about coupled flow-structural mechanical systems. Thereby, the discussion of computational aeroacoustics is extended towards perturbation approaches, which allows a decomposition of flow and acoustic quantities within the flow region. Last but not least, applications are updated and restructured so that the book meets modern demands.

This book presents a comprehensive and up-to-date account of the theory (physical principles), design, and practical implementations of various sensors for scientific, industrial and consumer applications. This latest edition focuses on the sensing technologies driven by the expanding use of sensors in mobile devices. These new miniature sensors will be described, with an emphasis on smart sensors which have embedded processing systems. The chapter on chemical sensors has also been expanded to present the latest developments. Digital systems, however complex and intelligent they may be, must receive information from the outside world that is generally analog and not electrical. Sensors are interface devices between various physical values and the electronic circuits that "understand" only a language of moving electrical charges. In other words, sensors are the eyes, ears, and noses of silicon chips. Unlike other books on sensors, the Handbook of Modern Sensors is organized according to the measured variables (temperature, pressure, position, etc.). This book is a reference text for students, researchers interested in modern instrumentation (applied physicists and engineers), sensor designers, application engineers and technicians whose job it is to understand, select and/or design sensors for practical systems.
