IOP Series in Sensors and Sensor Systems – serie

With the ability to monitor a vast range of physiological parameters, combined with wireless technology, wireless sensor networks and the Internet of Things, wearable sensors are revolutionising the field of digital health monitoring. In addition to applications in health monitoring, such technology is being used to monitor the state of our living environment and even the quality of our foods and the wellbeing of livestock. Written for scientists, engineers and practitioners by an international collection of authors, this book reviews the fundamentals of wearable sensors, their function, design, fabrication and implementation. Their application and advanced aspects including interface electronics and signal processing for easy interpretation of data, data transmission, data networking, data security, and privacy are also included.

Commencing by defining a set of standards for benchmarking sensors to enable better comparison, this book then proceeds to provide a review of the physics and workings of several optical and super optical biosensors, and introduces two more super optical biosensors, including the most sensitive super optical biosensor 'RMEPA', an abbreviation of three optical technique names: resonant mirroring, ellipsometry and attenuated total reflection. Mathcad is used to analyse these virtual biosensors and these codes and available to readers for use in their own research. It will be a key reference for researchers in academia and industry, particularly those involved in developing next generation optical biosensors.

This book describes the basic principles of electromagnetic induction measurements and consolidates the outcomes of recent research. It encompasses pipeline electromagnetic flow meters, electromagnetic flow meters, multiphase flow electromagnetic flowmeters and flow field of electromagnetic induction reconstruction. Though theoretical in nature it does draw on experimental data and includes new research findings, especially in the areas of multiphase flow and flow reconstruction. With a focus on theory and computation in flow measurement by electromagnetic induction including traditional flowmeters in closed conduits, velocity probe, two-phase flow, velocity reconstruction and dry calibration it will be an invaluable resource for researchers and practising engineers. The book uses MATLAB® to introduce efficient numerical methods to model and simulate flows, sensor construction and geometry, and the effect of pipe materials.

Key Features

Sensors are integral to modern living and are found in a huge number of applications in science, engineering and technology thus it is critical for scientists and technologists to understand the physical principles behind sensor types as well as their characteristics, applications, and how they can be suitably employed in sensor technologies. Whilst there exists a vast literature on the physics and characteristics of traditional sensors, this book provides a broad overview of the range of sensor technologies and attendant topics needed to optimise and utilise these devices in the modern world. Not only reviewing sensors by classification, the book encompasses the physics, design characteristics, simulation and interface electronics, and it includes case studies, future challenges and several other aspects of wider sensor technology to provide an overview of modern sensors and their applications. The broad scope will appeal to industrial and academic researchers and application engineers, especially those developing and implementing real-time hardware implementations employing smart sensors for emerging applications.

Key Features

The book may be of interest to a wide spectrum of readers, such as research scholars, academia, and industry professionals. It is especially for those who employ smart sensors for emerging applications such as robotic arms, cognitive applications, and brain-computer interfaces who may want an overview to gather general ideas for a certain technology that employs modern sensors.

Gas sensors are traditionally used as part of an industrial safety system, but they are also increasingly found in a range of settings including home and vehicle security, ventilation systems and environmental monitoring. The technology also holds great promise in non-invasive medical applications and as an essential component in the future Internet of Things. Metal oxide semiconductors are the most common materials exploited for gas sensing. However, in recent years there have been significant advances in both fundamental research and industrial development of gas sensors using new and novel materials. This is being driven by efforts to achieve better selectivity, higher sensitivity and lower power consumption as gas sensors are finding more widespread applications. This book reviews the developments and applications of traditional and emerging materials for gas sensors. Each chapter considers a sensor material and discusses the mode of operation, intrinsic material properties, preparation, device construction and areas of application opened by the novel modes of action and properties of the sensing material. With coverage spanning n- and p-type metal oxides, graphene, 2D metal chalcogenides, carbon nanotubes, ionic liquids and conducting polymer composites. This up-to-date synthesis will provide invaluable reading for industrial and academic researchers and engineers developing and exploiting new materials for the increasingly diverse areas of applications for modern gas sensors.
