Abstract

A sensor element can comprise a co-fired heater section, a sensing section, and a third insulating layer disposed between the electrode portion and the temperature sensor. The heater section can comprise a heater, a shield, and a temperature sensor, with a first insulating layer disposed between the heater and the shield, and a second insulating layer disposed between the shield and the temperature sensor. The sensing section can comprise an electrode portion and a sensing portion, wherein the sensing portion is disposed on a side of the electrode portion opposite the heater section.
