Development of simple portable blood glucose measuring devices

Probing biomedical materials with multiple wavelengths can not only obtain an in-depth understanding of the detected biomedical materials but also differentiate the materials. Biomedical materials have different optical properties (e.g., absorption and induction) for different wavelengths. Therefore, to achieve this purpose, we present in this study our experimental results on fabricating portable biomedical sensing devices. In this research phase, we assembled two types of system. One system used light sources with multiple wavelengths and photodetectors detecting these wavelengths, with which we preliminarily tested the absorbance of glucose solutions with different concentrations. The other was an Arduino-based glucose sensing system.
