CGMS AgCl A method of replenishing level of AgCl on a reference electrode of a electrochemical sensor

摘要

The AgCl replenishment system for a CGMS sensor according to an embodiment of the present invention includes a sensor unit capable of being transplanted into a body and formed in multiple layers so as to surround an outer circumferential surface of the tube and measuring the concentration of glucose in the body, A constant DC voltage for initiating an oxidation-reduction reaction of glucose and for promoting an electron transfer reaction, and a step for applying a stair-stepped ladder-type perturbation voltage in order to complement AgCl of the reference electrode of the sensor unit following the constant DC voltage And a microcontroller for controlling the digital-to-analog converter circuit and determining whether the concentration value of the glucose is within an error range by using the Λ-shaped stepped ladder-type perturbation voltage have.
