OXYGEN CHEMICAL SENSOR FOR HYDROPHILIC MEMBRANE

摘要

An oxygen sensor having an anode (18) and a cathode (16) spatially separated by a thin structurally rigid hyrophilic membrane (12). The hydrophilic membrane (12) is the host for a liquid electrolyte and confines the liquid electrolyte within the region between and in physical contact with anode (18) and cathode (16). An oxygen permeable membrane (24) disposed over the cathode (16) controls the quantity of oxygen reaching the cathode (16) and inhibits the evaporation of the liquid electrolyte.
