  • Patent number: 4536274
    Abstract: A transcutaneous blood carbon dioxide sensor together with a method for making such a sensor and for making electrodes used in the sensor. The sensor comprises a palladium/palladium oxide junction type electrode and a silver/silver halide junction type electrode applied to an electrically nonconductive substrate, partially coated with an insulative dielectric and partially coated with a polymeric membrane material including a bound electrolyte, the polymeric membrane material being permeable to carbon dioxide. The Pd/PD0 electrode was made cathodic prior to terminating the electro-oxidizing conditions.
