The advantages of a 1-µ-diameter platinum cathode in the Clark-type oxygen electrode are shown to be freedom from effects due to flow, stirring, or mechanical pressure. When used with a 5-mil polyethylene membrane the 1-µ electrode shows only a 2% difference between a vigorously stirred solution and the unstirred solution. A mechanical pressure of 200 psi on the 1-µ covered electrode caused only a 20% reduction in current. The use of a 1-µ covered electrode as an implant is suggested.
