Diabetes is one of common diseases nowadays that associated with inability of human body to control level of glucose in the body. The danger of the diabetes can be minimized by continuously monitor the glucose level of the patient. There are several methods to measure the glucose level in the blood either invasive, minimally invasive or non-invasive method. In this paper, we conducted an experiment using non-invasive near infrared approach to investigate the relationship between the level of the glucose and the corresponding sensing parameters. We used infrared LED as emitter and receiver. They are positioned opposite to each other with the sample in between. The LED transmitter driving current was varied from 40 mA up to 80 mA. There were 14 different level of glucose concentration were used as samples. We performed analysis on the collected received signals at the receiver when glucose level and LED driving current were varied. The results revealed that there is a linear relationship between the current applied to the LED and the received signal also known as sensing voltage. Different values of current applied to the transmitting infrared LED gave different levels of accuracy of glucose prediction. The optimal driving current was found at 60 mA, which provides the best accuracy as compared to 40 mA and 80 mA. In other words, 60 mA current has highest correlation factor and lowest error percentage. © 2021, Springer Nature Switzerland AG.
