First Claim
1. A method of stabilizing a sensor having a plurality of electrodes, the method comprising:
- (a) applying a first voltage to one of the plurality of electrodes for a first timeframe;
(b) applying a second voltage to said one of the plurality of electrodes for a second timeframe;
(c) measuring the sensor'"'"'s impedance; and
(d) based on the measured impedance, determining whether the sensor is stabilized, wherein the sensor is determined to be stabilized if the measured impedance exceeds a threshold value.

Abstract
A blood glucose sensing system includes a sensor and a sensor electronics device. The sensor includes a plurality of electrodes. The sensor electronics device includes stabilization circuitry. The stabilization circuitry causes a first voltage to be applied to one of the electrodes for a first timeframe and causes a second voltage to be applied to one of the electrodes for a second timeframe. The stabilization circuitry repeats the application of the first voltage and the second voltage to continue the anodic-cathodic cycle. The sensor electronics device may include a power supply, a regulator, and a voltage application device, where the voltage application device receives a regulated voltage from the regulator, applies a first voltage to an electrode for the first timeframe, and applies a second voltage to an electrode for the second timeframe.

10. A program code storage device, comprising:
-
a computer-readable storage medium; and a computer-readable program code, the computer-readable program code being stored on the computer-readable storage medium and having instructions, which when executed cause a controller to; (a) transmit a first signal to a digital-to-analog converter (DAC) that is coupled to an electrode of a sensor, the first signal being representative of a stabilization sequence of voltages that the DAC is to output to said electrode, wherein the stabilization sequence of voltages includes a first voltage applied for a first timeframe and a second voltage applied for a second timeframe; (b) transmit a measurement signal to initiate measurement of the sensor'"'"'s impedance; and (c) receive a second signal indicating whether the sensor is stabilized based on said impedance measurement, wherein the sensor is determined to be stabilized if the sensor'"'"'s impedance exceeds a threshold value. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
