According to the theory of non-invasive blood glucose measurement based on the method of conservation of energy metabolism,the sensor for non-invasive blood glucose measurement was designed and the mathematic model for it was derived. By multiple linear regression and principal component analysis, the data were processed, then the multiple linear expression was archived for blood glucose calculation and the two components contributing the most to the blood glucose were found. The experimental results indicated the correlation coefficient R was 0.86 between the test values and the true values of the blood glucose. So the experiments prove that solving the model of non-invasive blood glucose measurement with principal component analysis and multiple linear regression is feasible.
