Amperometric gas sensor
First Claim
1. An amperometric gas sensor for measuring a concentration of an analyte, comprising:
- a solid configured as an insulator without being contacted by the analyte, the solid comprising an ionically and electrically non-conductive polymer, the solid configured for diffusion of the analyte therethrough upon contacting the solid by the analyte and further configured to increase in electrical conductivity when in contact with the analyte;
a working electrode positioned on and in contact with the solid; and
a reference electrode positioned on and in contact with the solid, the reference electrode spaced apart and ionically and electrically insulated from the working electrode without the solid being contacted by the analyte, the working electrode and the reference electrode configured to measure electrical conductivity of the solid when the solid is in contact with the analyte.
