Ieee 1990 Ultrasonics Symposium

Surface acoustic wave (SAW) devices are recognized for their versatility and efficiency in controlling and processing electrical signals. This has resulted in a multitude of device concepts for a wide range of signal processing functions, such as delay lines, filters, resonators, pulse compressors, convolvers, and many more. As SAW technology has found its way into mass market products such as TV receivers, pagers, keyless entry systems and cellular phones, the production volume has risen to millions of devices produced every day. At the other end of the scale, there are specialized high performance signal processing SAW devices for satellite communication and military applications, such as radar and electronic warfare. This volume, together with Volume 2, presents an overview of recent advances in SAW technology, systems and applications by some of the foremost researchers in this exciting field.

This book contains 20 papers devoted to the domestic use of sensors. This up-to-date review fills a gap in the literature arising from the recent intense research and development of these sensors and takes an interdisciplinary approach to the operation principles of sensors and the preparation techniques, with particular regard to microelectronics techniques which allow the realization of sensor systems with integrated electronic circuitry.The applications of sensors in the domestic environment are accurately reviewed and the trends of future sensor development are also outlined.
