Abstract
In this study, a combination of Visible and Near Infrared (Vis-NIR) optical-based wearable sensor was proposed as an alternative design for the non-invasive blood glucose monitoring system. A unique information of the pulsatile to continuous components of the arterial blood volume pulsation and the capillaries blood volume during the change of glucose concentration in tissue has been exposed using reflected light signal in multiple optical wavelengths collected from subject`s wrist. Thus, an in-vitro experiment which enclosed six healthy subjects in a two-hour modified carbohydrate-rich meals tests has been conducted as an initial system-test. Results showed that the average correlation coefficient (Rp) between predicted and reference glucose value from all the tested subjects reached 0.85, with the standard error of prediction (SEP) of 7.70 mg/dL. Moreover, the clinical significance analysis using Clarke error grid (CEG) was also handled, with the results of all data points fell within the clinically acceptable region (Region A: 100 %).
