Abstract(in English) The measurements of skin impedance locus at high time-resolution is needed for evaluating stress, effects of acupuncturing and so on. It was reported that the time resolution of the measuring method of skin impedance locus that used step response of skin was high. However, the accuracy of the method is not sufficient at a high frequency range and the time resolution depends on the recovery time of subject. We found that the new method of measuring skin impedance locus using Fourier series does not have such problems in step response method. In this report, in order to check the validly of the new measuring method, we performed the numerical simulation and experimental measurements of a known impedance which imitated skin impedance. As a result, we found that the time resolution of the new measuring method was as high as the method that used step response and the measurement errors from 10 Hz to 1k Hz were less than 2%. Additionally, we applied the new method to measurements of the time course of skin impedance locus.
