Principles and Properties of Some Solid State Chemical Sensors
In medicine and biology sensory phenomena are studied already for a long time. A review has been given some years ago (Stiewe 1983). In the field of technique the demand for sensors has been induced by the fast development of semiconductor electronics. Often the computers require transducers for communication with the external world. Sensors are small electronic devices observing physical or chemical quantities and giving out a corresponding electrical signal. The computers accept this signal and turn out their result via read outs or actuators.
