"Mechanical Microsensors provides a comprehensive description of the various design techniques required for silicon micromachining of sensors. This is a very well written book which has a pleasant balance of mathematical, physics and engineering principles, that make this book suitable for physicists, chemistry, electrical and mechanical engineers." --SENSOR REVIEW "Of particular value is the fact that the authors go further than the description of the silicon sensor elements and also present solutions on how to interface these sensors to the surrounding world - electronically in the chapter on 'Electronic Interfacing' as well as physically in the chapter on 'Packaging'. To summarize, this textbook gives a comprehensive overview of mechanical microsensors which is especially well suited for students in courses on mechanical microsensors, but is also valuable for people in research and industry with an interest in this exciting and growing field." -MEASUREMENT SCIENCE AND TECHNOLOGY
