Sensors and Sensing in Biology and Engineering

Biological sensors are usually remarkably small, sensitive and efficient. It is highly desirable to design corresponding artificial sensors for scientific, industrial and commercial purposes.This book is designed to fill an urgent need for interdisciplinary exchange between biologists studying sensors in the natural world and engineers and physical scientists developing artificial sensors. Contributions from leading scientists in this area, whether engineers or biologists, are written to be accessible to readers from these and other disciplines. The main topics cover mechanical sensors, visual sensors and vision and chemosensors. Readers will obtain a fuller understanding of the nature and performance of natural sensors as well as enhanced appreciation for the current status and the potential applicability of artificial microsensors. Friedrich G. Barth was awarded the "Karl-Ritter-von-Frisch-Medaille at the 2003 Annual Conference of the German Zoological Society in Halle, Germany.

Provides current information on the nature and performance of natural sensors and potential applicability of artificial sensors First and unique publication with this interdisciplinary exchange between biologists (natural sensors) and engineers, physical scientists (artificial sensors) Written by leading international experts on these topics

Autorentext
Professor Friedrich G. Barth was born in Munich, Germany, in 1940. He studied biology and human physiology in Munich and Los Angeles. In 1967, he obtained his doctorate under H. Autrum, 1970 he received his Habilitation in zoology. In 1974, he was offered a chair at the University of Frankfurt/M. Since 1987, he has been professor at the University of Vienna, Austria. His main areas of research are neurobiology, sensory systems, and biomechanics. He is a member of several scientific academies and editor-in-chief of the Journal of Comparative Physiology A.
