Investigation Transillumination Mode at 660 and 780 nm for Non-Invasive Blood Glucose Monitoring Device

Abstract

Monitoring the level of blood glucose is required for diabetes to be managed. Monitoring one's glucose levels with finger prick blood is uncomfortable, unpleasant, and may cause infection. Regularly sticking one's fingers into sharp objects may result in scarring and calluses, reducing sensitivity and perception. Therefore, a blood glucose self-test that is not intrusive is very necessary. The optical blood glucose detection technique is promising and has opportunities for further improvement. This technology makes use of a variety of wavelengths, ranging from ultraviolet to infrared. The skin may be penetrated by low-energy radiation from light with a wavelength ranging from 450 to 2500 nanometers. Changes in light intensity, brought on by glucose's ability to absorb or scatter light, are used to measure blood glucose levels. Despite the extensive research on non-invasive methods, the commercial device is still under development. We summarize the results of experiments utilizing transmission modeling at 660 nm and 780 nm wavelengths. A measurement gadget has been designed to support the finger surveys conducted by volunteers. The VivaChek Ino is used to determine blood glucose levels, which are combined with other measurements to establish the findings of the measurements. The data from fifty different measurements were used to construct the regression lines. The correlation coefficient, R2, is close to 0.70. The findings of this research indicate that it would be possible to use an optical approach in conjunction with a transmission model. Additionally, it recommends mixing different near-infrared wavelength ranges to get superior outcomes.
