Identification of Blood Glucose Level Using NIR Sensor Non-Invasively

The measurement of blood glucose levels, without procedures, has been a standing challenge in medical diagnostics. This offers a more comfortable alternative to the used invasive treatments. Infrared (NIR) spectroscopy is a technology that allows for the indirect detection of blood glucose levels without the need for needles or drawing blood. This paper focuses on the aspects of measuring blood sugar levels using NIR sensors. NIR spectroscopy relies on the interaction between infrared light and biological tissues to leverage absorption patterns of glucose molecules in this wavelength range. By analyzing the transmitted or reflected light it becomes possible to extract information about blood glucose levels. The advantages of this approach include real time monitoring, reduced pain, lower risk of infection and improved patient compliance. This paper provides an explanation of NIR spectroscopy fundamentals calibration procedures required for accurate glucose level prediction as challenges associated with patient variability and sensor precision. It also discusses advancements in data processing techniques and sensor technology. Utilizing NIR sensors for invasive blood glucose monitoring holds great potential to enhance the quality of life for individuals with diabetes and promote proactive healthcare management. We are making progress towards the development of a nonintrusive technology that can continuously monitor blood glucose levels thanks to ongoing research and advancements in this field.
