Claim Text:
1. An amperometric gas sensor for measuring a concentration of an analyte, the sensor consisting essentially of: a solid consisting essentially of one or more non-conductive polymers and optionally an electrically non-conductive filler, the solid configured as an insulator without being contacted by the analyte and configured for diffusion of the analyte therethrough, the solid 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 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.
