Non-Invasive Blood Glucose Sensor: A Feasibility Study

Abstract

[EN] Diabetes is a chronic disease characterized by abnormal blood glucose levels which has short and long term complications. Management of diabetes relies on a regular control of blood glucose levels, commonly measured with invasive sensors, which are painful and cause patient discomfort. Scientific community is trying to develop noninvasive monitoring sensors to measure blood glucose continuously. Whereas previous work are focused on single methods and techniques, we present hereby a feasibility study of a non-invasive sensor integrating three different types of techniques: electromagnetic, acoustic speed and near infra-red spectroscopy. Our prototype is subject to different sources of bias, however, the cross-compensation of these three techniques can minimize the low performance of single-technique approaches. The results are promising and show the potential of using combined techniques for non-invasive blood glucose measurement.
