Abstract

We present a portable glucose monitoring system comprised of an implantable fluorescent-hydrogel sensor, wearable photo detector, microcontroller, wireless device and software for transdermal, continuous glucose monitoring. Although we showed the potential of the fluorescent-hydrogel fibers for applying to long-term, implanted glucose monitoring, “true” continuous glucose monitoring with a portable monitoring system has yet to be realized. In the system that we propose here, the calculated glucose values show a good correlation with the actual blood glucose concentrations. The portable device attached to the ear of a rat and measured the fluorescence intensity for three days. Therefore, our system shows the potential for practical, “true,” continuous glucose monitoring.

可植入荧光水凝胶微纤维的便携式连续血糖监测系统
我们提出了一种便携式血糖监测系统,该系统由植入式荧光水凝胶传感器、可穿戴式光电探测器、微控制器、无线设备和软件组成,用于透皮连续血糖监测。虽然我们展示了荧光水凝胶纤维应用于长期植入式血糖监测的潜力,但“真正的”便携式监测系统的连续血糖监测尚未实现。在我们这里提出的系统中,计算出的葡萄糖值与实际血糖浓度有很好的相关性。该便携式装置附着在大鼠的耳朵上,连续三天测量荧光强度。因此,我们的系统显示了实际、“真实”、连续血糖监测的潜力。
