NON-INVASIVE GLUCOSE MONITORING SYSTEM USING SWEAT MONITORING SENSOR

Diabetes mellitus claims millions of lives every year. It affects the body in various ways by leading to many serious illnesses and premature mortality. Heart and kidney diseases, which caused by diabetes are increasing at an alarming rate. In this paper, we report a study of a non-
invasive measurement technique to determine the glucose levels in the human body. Current existing methods to quantify the glucose level in the blood are predominantly invasive that involve taking the blood samples using finger pricking. In this paper, we report a spectroscopy based non-invasive glucose monitoring system to measure glucose concentration near infrared transmission spectroscopy is used and in vitro experiments are conducted, as well as in vivo. Our experimental study confirms a correlation between the sensor output voltage and glucose concentration levels. We report a low cost proto type of spectroscopy based non- invasive glucose monitoring system that demonstrates promising results in vitro and establishes a relationship between the optical signals and the changing levels of blood glucose concentration.
