摘要
本文通过对大量人体阻抗的测试,证实了Lafargue等人提出的人体阻抗ECFC模型,从理论上提出了计算ECFC模型中各电路参数的简化方法,由此所得的人体阻抗谱理论曲线与实验结果符合得很好。由于ECFC模型中各电路参数包含有人体成分的有用信息,因此分析这些参数的变化将有助于生物阻抗的医学应用。
Through measuring a number of human body impedances, the paper demonstrates ECFC model of human body impedance suggested by Lafargue and others, and theoretically puts forward a simplified method to calculate the electrical parameters in the model. The theoretical impedance spectrum obtained by our method accorols with experimental results well. Since the parameters in the ECFC model contains some useful information about components of human body, analyses of the changes of these parameters will help for the medical application of bioimpedance.
