METHOD OF AND SYSTEM FOR STABILIZATION OF SENSORS
First Claim
1. A method of stabilizing a sensor having a plurality of electrodes, the method comprising:
- (a) applying a voltage to one of the plurality of electrodes for a first predetermined time period;
(b) waiting a second predetermined time period with no voltage application;
(c) measuring an electrical characteristic of the sensor; and
(d) based on the electrical characteristic measurement, determining whether the sensor is stabilized.

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.

14. 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 voltage that the DAC is to apply to said electrode for a first predetermined time period; (b) transmit a second signal instructing the DAC to refrain from applying any voltage to said electrode for a second predetermined time period; (c) transmit a measurement signal to initiate measurement of an electrical characteristic of the sensor; and (d) receive a third signal indicating whether the sensor is stabilized based on said electrical characteristic measurement. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26)
