Research on noninvasive glucose measurement based on metabolic heat conformation method

A noninvasive glucose measurement system is proposed using metabolic heat conformation method, which is based on the discovery that the heat quantity dissipated in metabolism is the function of glucose level and the quantity of oxygen supply. Temperature sensors, infrared sensors, moisture sensors and optical measurement device are applied to get the glucose level by measuring heat dissipation, blood flow rate of the local tissue and local blood oxygen level. The measurement system composition and data processing method as well as the possible sources of the measurement errors are introduced. In clinical test, comparing with the test results obtained from large automatic biochemical analyzer, the correlation coefficient of the system test results equals to 0.856, which proves that the proposed method is feasible.
