Diabetes is characterized by insulin resistance, which can cause issues if undetected and mistreated. Regular monitoring of blood glucose levels is necessary to prevent complications. Conventional diabetes checkup relies on invasive blood punctures that can cause calluses and spread infections if not handled meticulously. To address issues of diabetic patients such as painful insertions and discomfort associated with it, recently much work has been done in the field of non-invasive glucometers. The purpose of this research is to develop a near-infrared (NIR at 950 NM) blood glucose monitoring system that is non-invasive and affordable. The device will employ an In-Vitro glucose measurement prototype that detects diffuse reflectance spectra of blood from human fingers and forearms to ensure sensitivity in fluctuating glucose concentrations at a very low cost.
