Non-Invasive Blood Glucose Monitoring System Using Near-Infrared Spectroscopy: A Prototype Design

This research study focuses on designing a non-invasive prototype for monitoring blood glucose levels using near-infrared spectroscopy. Diabetes is one of the most common chronic diseases globally, and the invasive methods do not always offer accurate readings as they are affected by several factors, such as the presence of dirt on the skin, not applying enough blood to the strip, and more. Hence, discovering non-invasive methods is essential for painless and accurate detection of blood glucose concentrations. The rationale for this new research lies in the development of novel methods to monitor blood glucose levels. The research methods involve ideating and designing a prototype of the device, involving the required hardware components as well as the key software filters needed for the device to function effectively. The study’s significant findings demonstrate that it is possible to detect blood glucose levels using NIR light and analyze them using a photodiode and a microcontroller, making future enhancements in this field possible. The significance of this study lies in its contribution to improving the current methods for monitoring glucose levels by making sure the newer method is painless, reliable and not impacted by external factors.
