Summary
Summary
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.

Choice Review
Gautschi (ETH, Switzerland) presents applications of piezoelectric, mainly quartz, active sensors for primarily mechanical and industrial uses from a practical engineering perspective. Most suitable for users of sensors, the volume includes substantial references to general background, relevant standards, and contact information for 33 manufacturers. Coverage of specific devices for well-defined uses is extensive: force, torque, strain, pressure, acceleration, acoustic emission, and associated amplifiers. Operational limitations, practical problems, electronic compatibility, measurement standards, and clear attention to calibration and boundary conditions are well highlighted. The advantages of niche market piezoelectric crystals, e.g., tourmaline, langasite, and lithium niobate, are noted. However, coverage of polymer and ceramic piezoelectrics is absent or limited, respectively. The text is readable--although numerous typographical errors and remnants of the initial German grammar occasionally will give readers pause. Most chapters begin with a clear definition of critical terms and measurands (true values of qualities)--especially useful since sensors are used in disparate fields. Numerous engineering drawings clarify device construction; additional figures show common instrumentation modules. Overall, this is a useful update on sensor technology providing practical guidance to supplement manufacturer notes. Professionals and practitioners. S. M. Pilgrim Alfred University
