Non-invasive Blood Glucose Determination using Near Infrared LED in Diffused Reflectance Method

Diabetes Mellitus is one of the notable health concerns around the globe. To keep diabetes in check a patient needs to track his/her blood glucose level regularly. In the traditional invasive system, a patient needs to prick his body part to collect the blood sample, which deems to be painful for the patient. Non-invasive blood glucose measurement can diminish the pain. In this paper, we proposed a non-invasive blood glucose determination method where a NIR LED (940nm) and a photo-detector is used to determine the blood glucose concentration. We used the diffused reflectance method to determine the blood glucose concentration in our paper. After implementing the device, we compared the data between our device and established invasive blood glucometer available in the market. Clarke grid error analysis shows, that most of the measured data by the device are within Region-A.
