Affordable noninvasive continuous blood glucose concentration monitoring via interferometry and thermal technology

Celestine Wenardy, Indonesia The Virgin Galactic Pioneer Award, 13-15

I have developed an unprecedented noninvasive continuous glucometer that allows for the regular monitoring of blood glucose concentration without drawing blood. This glucometer is highly accurate, achieving a coefficient of determination of 0.843, despite only costing about $63 in comparison to over $1,000 for invasive glucometers available in the market. This was achieved by incorporating two sensors. The first uses interferometry, involving the relationship between the refractive indices of the skin (and therefore the amount of light reflected towards a certain area) and glucose concentration. The second mechanism uses thermal technology, which utilizes the correlation between the heat capacity of skin and glucose concentration.
