Abstract
A sensor including a species selective electrode and a reference electrode having an electrolyte layer disposed therebetween; a reference gas channel in fluid communication with the reference electrode; a heater and a temperature sensor; wherein the species selective electrode is disposed on a first side of an insulating layer separating the species selective electrode from the electrolyte layer, the insulating layer having a first substantially solid area and a second area having an opening pattern extending through the insulating layer; the species selective electrode comprising a species sensing electrode portion disposed on the opening pattern of the insulating layer so as to contact the electrolyte layer through the opening pattern and a non-active electrode lead portion disposed over the first substantially solid area so that the non-active electrode lead portion is in electrical communication with the species sensing electrode portion and is free from contact with the electrolyte layer.
