Non-Invasive Blood Glucose Monitoring Device

Diabetes Mellitus is chronic disease affecting the people of all age groups around the globe. It is a very common disorder which causes high levels of sugar in the blood stream. High levels of blood glucose can damage the tiny blood vessels in our heart, eyes, kidneys and nervous system. Diabetes is fast gaining the status of a potential epidemic in India with more than 62 million diabetic individuals currently diagnosed with the disease. Invasive method is the most common method used to measure the blood glucose level which involves blood loss and pain. In the proposed proposal, a novel device has been designed to measure and monitor the blood glucose levels non-invasively. This device measures the blood glucose by spectroscopy technique using Red laser, in which the red laser shows better transmission and linearity when it passes through the blood. It measures the glucose value by detecting refractive index of transmitted light which is based on the principle of Snell’s law. The device will be further designed and fabricated in the form of a band to monitor blood glucose continuously.
