Non Invasive Blood Glucometer

Diabetes is a metabolic pathological condition of concern, which affects vital organs of body if not diagnosed and treated on time. Regular monitoring of blood glucose is important to avoid complication of diabetes. Commonly used glucose measurement methods are invasive which generally involves finger puncturing. These methods are painful and frequent pricking cause calluses on the skin and have risk of spreading infectious diseases. Therefore there is need to develop a non-invasive monitoring system which can measure blood glucose continuously without much problem. The present work is focused on development of non-invasive blood glucose measurement sensor system using Near-infrared (NIR) technique. In this study, near infrared optical measurement is applied to overcome the invasive issues. The designed device consists of an infrared emitter which placed over the fingertip for measurement of blood glucose optically. The near-infrared light will be sensed by the photo diode which having a certain wavelength. The intensity of received light is depending on the glucose molecules inside the blood. By analyzing the variation in voltages received after reflection in the cases the current diabetic condition as well as the approximate glucose level of the individual is going to be predicted. The obtained results are going to be validated with glucose meter readings and statistical analysis of the readings is to be done.
