Beschreibung
Zusammenfassung:	A sensor including a species selective electrode (50) and a reference electrode (56) having an electrolyte layer (58) disposed therebetween; a reference gas channel (80) in fluid communication with the reference electrode (56); a heater (90) and a temperature sensor (84); wherein the species selective electrode (50) is disposed on a first side of an insulating layer (60) separating the species selective electrode (50) from the electrolyte layer (58), the insulating layer (60) having a first substantially solid area (55) and a second area (54) having an opening pattern (66) extending through the insulating layer (60); the species selective electrode comprising a species sensing electrode portion (68) disposed on the opening pattern (66) of the insulating layer so as to contact the electrolyte layer (58) through the opening pattern (66) and a non-active electrode lead portion (52) disposed over the first substantially solid area (55) so that the non-active electrode lead portion (52) is in electrical communication with the species sensing electrode portion (68) and is free from contact with the electrolyte layer (58).
