Title:
GAS SENSOR USING SOLUBLE CONDUCTIVE POLYMER
Document Type and Number:
Japanese Patent JP2002039982
Kind Code:
A
Abstract:

To provide a gas sensor which is useable semi-permanently by reversible adsorption and desorption of gases, superior in workability, capable of being easily manufactured with high reproducibility, and superior in the immediate effectiveness, accuracy, and speediness of sensitivity for detecting gas components.

In the gas sensor, detection is performed based on changes in the electrical resistance value or in the color tone of a soluble conductive polymer with a sulfonic group and/or a carboxyl group.
