Abstract
Oxygen sensing as disclosed herein is performed by applying a solid state, self-heating sensor to the patient's skin. A noble metal cathode and a thick-film reference electrode are provided on the front face of a thin flat substrate employed in the sensor. A thick-film resistive heater is provided on the back surface of the substrate for heating the sensor to produce hyperemia in the adjacent tissue so that a polarographic measurement of oxygen concentration may be obtained by means of the electrodes on the front face.
