Beschreibung
Zusammenfassung:	A method for making a sensor is disclosed. The method comprises: disposing an electrolyte between a first side of sensing electrode and a first side of reference electrode, disposing a first side of a protective layer adjacent to said a second side of said sensing electrode, applying a mixture of a metal oxide, a fugitive material, and a solvent to a second side of the protective layer, and calcining the applied mixture to form said a protective coating on the second side of the protective layer.
