Study on Multi-frequency Electrical Impedance Parameter Measuring System on Human Limb
In this paper, the multi-frequency electrical impedance parameter measuring system on the limb is developed. Its composition theory and structure are discussed. The electrical impedance parameter of forearm under the ischemia and normal condition and the parameter of lower limb under work load condition are measured by this instrument respectively. The results show that this instrument can accurately differentiate the abnormal and normal condition of the limb. It is shown that the impedance model parameters Ri, Re and Cm can be used as an important indicator to accurately distinguish the tissue from various physiological conditions, especially Ri can significantly differentiate limb from the different physiological state.
