Sensor technologies have experienced dramatic growth in recent years, making a significant impact on national security, health care, environmental improvement, energy management, food safety, construction monitoring, manufacturing and process control, and more. However, education on sensor technologies has not kept pace with this rapid development ... until now. Resistive, Capacitive, Inductive, and Magnetic Sensor Technologies examines existing, new, and novel sensor technologies and—through real-world examples, sample problems, and practical exercises—illustrates how the related science and engineering principles can be applied across multiple disciplines, offering greater insight into various sensors’ operating mechanisms and practical functions. The book assists readers in understanding resistive, capacitive, inductive, and magnetic (RCIM) sensors, as well as sensors with similar design concepts, characteristics, and circuitry. Resistive, Capacitive, Inductive, and Magnetic Sensor Technologies is a complete and comprehensive overview of RCIM sensing technologies. It takes a unique approach in describing a broad range of sensing technologies and their diverse applications by first reviewing the necessary physics, and then explaining the sensors’ intrinsic mechanisms, distinctive designs, materials and manufacturing methods, associated noise types, signal conditioning circuitry, and practical applications. The text not only covers silicon and metallic sensors but also those made of modern and specialized materials such as ceramics, polymers, and organic substances. It provides cutting-edge information useful to students, researchers, scientists, and practicing professionals involved in the design and application of sensor-based products in fields such as biomedical engineering, mechatronics, robotics, aerospace, and beyond.

With their similarity to the organs of the most advanced creatures that inhabit the Earth, sensors are regarded as being the “senses of electronics”: arti?cial eyes and ears that are capable of seeing and hearing beyond the range of - man perception; electronic noses and tongues that can recognise odours and ?avours without a lifetime training; touch that is able not only to feel the texture and temperature of the materials but even to discern their chemical compo- tion. Among the world of chemical sensors, optical devices (sometimes termed “optodes”, from the Greek “the optical way”) have reached a prominent place in those areas where the features of light and of the light-matter interaction show their advantage: contactless or long-distance interrogation, detection sensitivity, analyte selectivity, absence of electrical interference or risks, and lack of analyte consumption, to name just a few. The introduction of optical ?bres and integrated optics has added more value to such sensing since now light can be con?ned and readily carried to dif?cult-to-reach locations, higher information density can be transported, indicator dyes can be immobilised at the distal end or the evanescent ?eld for unique chemical and biochemical sensing (including multiplexed and distributed measurements), optical s- sors can now be subject to mass production and novel sensing schemes have been established (interferometric, surface plasmon resonance, ?uorescence energy transfer, supramolecular recognition . . . ).

The fusion of information from sensors with different physical characteristics, such as sight, touch, sound, etc., enhances the understanding of our surroundings and provides the basis for planning, decision-making, and control of autonomous and intelligent machines. The minimal representation approach to multisensor fusion is based on the use of an information measure as a universal yardstick for fusion. Using models of sensor uncertainty, the representation size guides the integration of widely varying types of data and maximizes the information contributed to a consistent interpretation. In this book, the general theory of minimal representation multisensor fusion is developed and applied in a series of experimental studies of sensor-based robot manipulation. A novel application of differential evolutionary computation is introduced to achieve practical and effective solutions to this difficult computational problem.

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.

In this thesis, a novel sensor network paradigm is proposed and studied, inspired by the fusion of wireless communication, localization and imaging. Wireless sensor networks will open a fascinating world of ubiquitous and seamless connectivity not only between individuals but also between devices and objects in our daily life. The key to this vision is a universal low-power, low-complexity and low-cost transceiver unit that provides scalable data communication as well as location and environmental information. Ultra-Wideband (UWB) technology with its rich design space can meet the challenging requirements of future wireless sensor networks. This is the consequence of a paradigm shift compared to narrowband communication: due to the huge bandwidth available, we can trade off bandwidth efficiency against other figures of merit. The major design criterion is not data rate anymore, but rather power consumption and hardware complexity. Within the group of hardware-aware system designs, UWB impulse radio with energy detection receivers are of particular relevance and well known for their efficient implementation. The contribution of this thesis is the comprehensive study of sensor networks with generalized energy detection receivers, where we focus on innovative and efficient approaches for communication and localization and their synergy.

Progress in optical fiber sensors The field of optical fiber sensor technology is one that continues to expand and develop at a rate that could barely have been predicted a few years ago. The wealth of publications appearing in the technical literature and the burgeoning number of papers presented at the now well-established series of national and international conferences, which are attended by a wide selection of technically qualified optoelectronics professionals, gives a clear indication of both the range and scale of the devices and applications now seen in the subject. Such a rapid expansion makes it very difficult for the scientist and engineer, under pressure to be both informed and effective for an employer, to attend all these meetings, selectively read the appropriate literature and be able quickly to gain the knowledge in those specific areas which will give the best advantage for the work in hand. To that end, this volume has been planned and carefully designed to provide an essential overview, and detailed specific information, on those novel and exciting aspects of optical fiber sensor technology that have recently emerged, with particular focus on the devices and the exciting applications of this part of optoelectronic technology in the vast international measurement and instrumentation area.
