When the search of the Chemical Abstracts data base was done for the purpose of this review, it netted over 1500 references under the general entry of chemical sensors for the period between January 1985 and December 1987; chemical sensor is undoubtedly a popular object. But, what is it. It seems that so far nobody has been able to give an unambiguous and universally accepted definition. They have not attempted to do this either, but because the review had to be written within the context of some rules, they had to come up with their own definition for which they claim no validity beyond these pages. According to them a chemical sensor is a transducer which provides direct information about the chemical composition of its environment. It consists of a physical transducer and a chemically selective layer. The four fundamental transduction modes by which this review is divided are thermal, mass, electrochemical, and optical.
