Abstract
A glucose sensing apparatus and method includes an electrocatalytic sensor having a reference electrode and a sensing electrode. A periodic signal is comprised of a ramp voltage which is intermingled a series of square wave measurement pulses. This signal is applied to the sensor. Current levels are sampled twice during each measurement pulse, and a signal indicative of glucose level is derived therefrom. After completion of a measurement, a reactivation, signal is applied to the electrode to regenerate deteriorated surfaces thereof.
