This report is on the preliminary development of a new kind of oxygen sensor. Based on sensing a potentiometric signal from oxygen-specific compounds, this approach offers a potentially stable, reliable, and vastly simplified sensor. The report represents two configurations for the oxygen-specific compound oxygen reagent. One makes use of the reagent in a thin solution film confined by a membrane. The other uses the reagent immobilized in a polymer film, without any additional solvents. This last embodiment is essentially a solid-state probe of oxygen. This report demonstrates the feasibility of such an approach by reviewing relevant work dealing with 1 proof of principle, 2 calibration curves over a range of oxygen pressure, 3 temperature effects, and 4 pressure effects.
