Calibration of the Circuit Measurement for the Glucose Sensor

摘要

The extended gate field effect transistor (EGFET) has many advantages such as the fabrication is easy, low cost, easy to operate etc. The EGFET was applied to biosensor in recent years. In this study, the tin oxide (SnO_2) pH sensitive membrane was deposited on ITO glass, when the surface voltage which pH membrane changes, the gate voltage and current channel of MOSFET will change immediately to detect concentration of the glucose sensor. In this study we have devoted to research about the calibration of the circuit measurement for the glucose sensor, and study the calibration system of the drift and hysteresis.
