Title:
ODOR SENSOR AND ODOR MEASUREMENT SYSTEM
Document Type and Number:
WIPO Patent Application WO/2017/085796
Kind Code:
A1
Abstract:
This odor sensor includes at least two sensor elements which are provided with a substance adsorption membrane which adsorbs at least one odor substance contained in the air and with an electric signal conversion unit which measures electric properties of the substance adsorption film after adsorption of said substance, characterized in that the substance adsorption film includes a basic skeleton that includes a conductive polymer and a dopant which modifies the basic skeleton of the conductive polymer, and the substance adsorption membrane in the at least two sensor elements each has a different ratio of the basic skeleton and the dopant. This odor measurement system uses said sensor.
