The present research work is the part of the feasibility study to implement non-invasive blood-glucose sensing using microwave-based sensor. The one-port microstrip patch antenna sensor developed to exhibit variation in its electromagnetic response with respect to blood-glucose level. It has been demonstrated through in vitro controlled experiment under laboratory conditions. The novel multi-parameter-based sensitivity factor termed as GlucoSense was also defined to evaluate the sensitivity of sensor towards the change in glucose concentration. It was established that there was a good correlation between sensor’s reflection properties and glucose concentration. The findings of the controlled experiment convincingly proved that the sensor has the potential to be effectively used for developing a suitable device for non-invasive blood-glucose sensing.

本研究工作是使用微波传感器实现无创血糖传感的可行性研究的一部分。开发出一种单端口微带贴片天线传感器，以显示其相对于血糖水平的电磁响应变化。通过实验室条件下的体外对照实验已证明了这一点。基于多参数的新型灵敏度因子称为GlucoSense还定义了传感器来评估传感器对葡萄糖浓度变化的敏感性。已确定传感器的反射特性与葡萄糖浓度之间存在良好的相关性。受控实验的结果令人信服地证明，该传感器具有潜力，可以有效地用于开发合适的无创血糖传感设备。
