Prototype Development of Iot-Based Blood Glucose Level (BGL) Monitoring System Using Galvanic Skin Response (GSR) Sensor

Abstract

Understanding the blood glucose characteristic of diabetes patient help in medication prescription, food intake and exercise routine to maintain optimal blood glucose levels (BGLs) and improve the patient's overall lifestyle. The conventional 'test-strip' approach commonly monitors a patient's BGL using a drop of blood from the fingertip. It is sometimes inconvenient for some people to continuously take the blood sample a few times daily. The main idea of this study is to apply the noninvasive monitoring approach as an alternative to the conventional invasive method. Nowadays, various devices have been used to monitor BGLs using noninvasive techniques, such as an infrared or Galvanic Skin Response (GSR) sensor. In this study, we are developing the prototyping devices of a noninvasive blood glucose monitoring system using the GSR sensor approach. Previous studies showed that utilising this GSR sensor with controlled parameters of skin temperature and applied pressure will result in a more stable correlation between blood glucose and GSR reading. Thus, in this project, we are developing a device prototype that uses a GSR sensor with a controlled skin-applied pressure and temperature parameter. This project was divided into software and hardware components codesign development using a Model-Based Embedded System Design & Prototyping approach. By the end of the project, the first proposed prototype of a blood glucose monitoring device is presented with a stated requirement functionality.
