Non-invasive tracking and monitoring glucose content using near infrared spectroscopy

Diabetes is deliberate as one of the major contributors of crystallize infirmity and death in non-infectious diseases. Common method for determination of blood glucose concentration is using a self-monitoring glucose meter. This process requires pricking the finger and pry out the blood from the forearm and doing the chemical analysis with the help of disposable test strips. The pain and difficulty caused by this method have lead to the evolution of a noninvasive method. This method makes use of a near infrared sensor for transmission and reception of rays from fingertip. Near-infrared (NIR) is passing through the fingertip, before and after obstructing the flow of blood. By explicate the variation in received signal intensity achieved after reflection in both the cases, glucose present in blood can be predicted and wirelessly transmitted to a remote PC. The results show the potential of glucose measurement using Near-infrared.
