Abstract:
A method for producing an oxygen sensor, comprising:preparing a first electrolyte layer by forming a hole in a first material, said hole having a first hole geometry and first hole size; disposing a first electrolyte in said first hole, wherein said first electrolyte has a first electrolyte geometry and a electrolyte size substantially equivalent to said first hole geometry and said first hole size; laminating said first electrolyte layer; forming a hole in said second material, said hole having a second hole geometry and second hole size; disposing a solid electrolyte in said second hole, wherein said solid electrolyte has a solid electrolyte geometry and a solid electrolyte size substantially equivalent to said second hole geometry and said second hole size; depositing an outer electrode on said laminated first electrolyte layer; depositing an inner electrode on a solid electrolyte layer; depositing a reference electrode on a reference electrode layer; depositing a heater on a heater side of a heater layer; stacking said solid electrolyte layer and said first electrolyte layer such that said inner electrode is disposed therebetween, in contact with both said solid electrolyte and said first electrolyte, and in ionic communication with said outer electrode; disposing a first side of said reference electrode layer adjacent to said solid electrolyte layer such that said reference electrode is in contact with said solid electrolyte; disposing said heater side of said heater layer on a second side of said reference electrode layer; and laminating said first electrolyte layer, said solid electrolyte layer, said reference electrode layer and said heater layer together.
