Latest Patents
One of his latest inventions is the Transcutaneous Galvanic Electrode Oxygen Sensor. This device is designed to measure transcutaneous oxygen pressure (pO₂) and features a cathode made of a porous film of metal below hydrogen in the Electromotive Series. It also includes an anode of a metal above hydrogen in the Electromotive Series, an electrolyte, and an oxygen-permeable membrane that contacts the skin of a patient. Additionally, the sensor may incorporate a temperature measuring device to compensate for temperature variations.
Another significant patent is the Implantable Glucose Sensor. This method and apparatus provide more accurate measurements of glucose content in body fluids by sensing the absolute level of oxygen concentration. The system corrects the output differential measurement indicative of glucose content according to the absolute level of oxygen. To account for temperature variations, a thermistor may be included in the electrode system, as both the absolute oxygen reading and the rate of glucose oxidation are sensitive to temperature changes.
