Abstract

Diabetes Mellitus is one of the most common life threatening diseases in the world.Malaysia is ranked 10th in the world with the highest number of population with diabetes.The aim of this project is to implement a low power wearable system for continuously monitoring the glucose level in human blood by using GSR sensor.The development of non-invasive blood glucose level detector is desired to replace the invasive method which is inconvenient and expensive.This project is successfully detected the GSR value and establishing a correlation between GSR and the blood glucose level.This project was divided into two parts,which are the hardware implementation and software implementation.The GSR conditional circuit is being optimized into a compact and convenient for the end user by fabricated in SMT.For the software implementation,the Bluno Beetle microprocessor is developed to collect and save the user data and an Android Application is created to link together with the hardware prototype by using BLE.It is also a IoT devices where the end user can review their data in an online database.It is clearly demonstrated that GSR can be useful in assisting to determine the blood glucose level as an alternative method for non-invasive approach.A correlation of 65.73% was found from the result and a threshold of (+-2V) for GSR data is identified for the end user to alert on their BGL.However,there are some factor such as dynamic movement, temperature and calories burnt might affect the accuracy and precision of the prototype.
