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
- Features a broad review of sensor types, including MEMS, wearable and smart sensors
- Presents application of modern sensors and emerging research directions
- Incorporates case studies
- Reviews wider associated technologies such as simulation, materials and interface electronics
- Interdisciplinary appeal making the text suitable for industrial and academic researchers as well as application engineers
