Piezoelectric Sensorics

Sensors are the key to life and survival - and to the success of modern technology. Nature has provided living creatures with a wealth of sensors for a variety of measurands, such as light, sound, temperature, speed, motion, distance, force, pressure, acceleration, odor and so on - sensors, whose performance and specifications have often not been matched yet by man-made devices. Even at today's high level of electronics and information technology, sensors remain the crucial and decisive interface needed to reliably relate phenomena occurring in the environment to corresponding electric signals that can be processed to obtain the desired information and subsequent correct reaction of systems. Although the literature on sensors is extremely vast, there is one type of sensors which so far has received little attention: the piezoelectric sensor. Certainly, most handbooks on measurement mention briefly this type of sensor yet there is not a single book in the English language dedicated entirelyto piezoelectric sensors and giving a reasonably complete overview. There are only the books by [Gohlke 1955 and 1959] and [Tichy and Gautschi 1980], all in German.

Klappentext
This book covers the entire field of piezoelectric sensors for mechanical measurands. Scientists, engineers and technicians, as well as students in engineering will find in this book for the first time a complete overview of this special type of sensors. Extensive practical advice is given throughout the text allowing the reader to profit from the authors many years experience. The book offers an overview of the most important piezoelectric materials and their properties as well as a consistent terminology for describing sensors. It contains a description of sensors for force, strain, pressure, acceleration, and acoustic emission and an in-depth description of the special electronics used with piezolectric sensors. Informations on calibrating sen- sors and electronics are given, as well as numerous examples of practical applications.
