A wireless blood sugar monitoring system using ion-sensitive Field Effect Transistor

Abstract

Ion sensitive Field Effect Transistor (ISFET) is popularly known for its numerous applications in the field of Biomedical Engineering. In this paper, we manually built a glucose sensor from ISFET. The Glucose sensor is then interfaced to a microcontroller to implement a glucometer. A Wifi module is then embedded to the system to allow a doctor to wirelessly monitor the blood sugar level of his patients through the network. A user friendly GUI is also created for the convenience of the doctor in accessing patients' record. A database is also created for each patient to allow the doctor to keep the patients record individually.
