In the light of the increasing prevalence of diabetes, research on non-invasive blood sugar measuring devices have begun to be developed, one of which utilizes infrared spectroscopy methods. This method uses a pair of IR LED and photodiode placed in line. In doing so, the location of its placement in the human body has to be considered, thereby enabling the photodiode to capture the light emitted by the IR LED. Therefore, the voltage data generated by the photodiode circuit in several parts of the body is taken as the representation of the ability of the photodiode to absorb infrared light. A higher voltage value is captured in the range of 1 Volt when the sensor is on the finger. Meanwhile, there is no voltage read on the wrist. The results of this study will be used as a reference to determine the location of the sensor placement in the designed blood glucose monitoring device. © Published under licence by IOP Publishing Ltd.
