Abstract
A polymeric gas sensor utilizes a variety of electrode geometries to generate varied responses to selective gases. The characteristic response to various gases of each electrode geometry permits the construction of a gas sensor having desirable and reproducible characteristic responses to specific gases. The gas sensor array of the invention produces characteristic responses from a plurality of sensors. These responses collectively produce a characteristic response pattern that can be used for the identification of specific gases with pattern recognition techniques.
