A Non-Invasive Blood Glucose Monitoring Device

Diabetes and its complications impose, in addition to health risks, significant economic consequences on individuals, families, health systems and countries. Research has conclusively shown that improved glucose control reduces the long-term complications of diabetes. Currently, the problem lies in the inconvenience, expenses, pain, and complexity involved in conventional (invasive) self-monitoring of blood glucose (SMBG) that led to its underutilization. It was estimated in 2017 that approximately 629 million people around the globe would have diabetes by the year 2045. This paper proposes a non-invasive blood glucose monitoring device prototype called Glucotect. It is a non-invasive solution that uses Near Infrared (NIR) technology in order to allow anyone, after initial calibration, to monitor his/her blood sugar without having to draw blood. Preliminary tests show an accuracy improvement of about 8% when compared to the invasive device currently in use.
