More Information
Summary:An exhaust sensor comprises a sensing electrode and a reference electrode each in contact with an electrolyte. At least one of the sensing electrode and the reference electrode are formed by depositing an electrode precursor material on an electrolyte precursor material and sintering the combination at a sufficient temperature for a sufficient time to achieve densification of the electrolyte, wherein the electrode precursor material comprises an alkali salt. Electrode patterns having enhanced perimeter ratios are also disclosed. The resulting exhaust sensor is capable of providing a usable output at a reduced operating temperature.
