Abstract
A high frequency impedance monitoring system based on impedance spectroscopy has been developed
whose frequency ranges of 10
60 MHz
applied for human body test. According to principle of non-invasive glucose measuring based on impedance spectroscopy
after testing on healthy body
112 groups of data are collected; use principal component analysis regression model to predict glucose concentration
compare predicting results and invasive data from the same tester
correlation coefficient is 0. 805 8
dynamic glucose change trend can be well predicted
provide reference for further study of non-invasive continuous monitoring of glucose levels.
