GlucoScan: Noninvasive Glucose Monitoring Device

Prediabetes impacts many worldwide and may progress to diabetes. Prediabetes may be treatable, but most are unaware they have it. This paper proposes a new device for non-invasive measurement of change in blood glucose through a wearable finger clamp system using optical spectroscopy with visible wavelengths. Change in blood glucose discretely and over time provides valuable information for health tracking, prediabetes, and diabetes.
