Analyzing the Human Blood Glucose Level Trend (Up or Down) by Using Optical Polarization

Large amount of people having diabetics in the world, and it is increasing very rapidly. Diabetics should to check their blood glucose level at least four times a day. When controls are not done regularly, risk of hypoglycemia and hyperglycemia may arise. There are ongoing researches for developing non-invasive methods as an alternative to finger piercing, which is the most commonly used and painful method for patients. In this study, although a physical glucometer design has not been completed yet, it has been demonstrated which wavelength ranges and which parameters can be used for non-invasive device. Most importantly an empirical relationship has been established between the level of blood sugar and de-polarization disturbance seen in circularly polarized light. The proposed equation can estimate the blood glucose level based on de-polarization information with an average error rate of 1%.
