Research on Bioelectrical Impedance Analysis Method Based On Eight-Segment Impedance Model

Bioelectrical impedance is one of the most important parameters in body composition prediction, reflecting physiological condition of human body to a certain extent, but its accurate measurement is of great difficulty. Although eight-segment model has been established to analyses bioelectrical impedances, there is not a comprehensive analysis method currently. In order to solve this problem, we have proposed the impedance analysis method based on eight-segment model, and verified the correctness of this method through theoretical derivation and experimental verification. The results have shown that the impedance analysis method based on eight-segment model can provide more accurate impedances to predict body composition, which is a considerable improvement for the impedance analysis method.
