Document Type and Number:
Japanese Patent JP3084006
Kind Code:
B2
Abstract:
A sensor (10) for reversibly detecting target volatile material in the gas phase comprises a dielectric substrate (12) having a major surface, a pair of electrically conductive electrodes (14a, 14b) disposed on said major surface of said substrate (12), and a conductive polymer (16) covering said pair of electrically conductive electrodes (14a, 14b), said conductive polymer (16) doped with appropriate dopants, said dopants present in said conductive polymer (16) in measurable excess of said stoichiometrically required to change said conductive polymer (16) from a neutral state to a charged state to provide requisite conductivity, said sensor (10) being capable of detecting the presence of said target volatile material at a concentration of less than about 500 ppm.
