Abstract
Measurement of skin impedance locus at high time-resolution is needed for evaluating stress, effects of acupuncturing and so on. In this report, we proposed a new measuring method of the skin impedance lo-cus which have advantages over the previous methods. In order to check the validity of a new measuring method in actual measurements, we performed measurement of the time variation in skin impedance locus at high time-resolution using the new method. We examined how the skin impedance locus change with auditory stimulus and quantified the change in skin impedance locus. As a result, we confirmed that the measurements precision and the time-resolution of the new measuring method were enough for measuring the temporal variation in skin impedance locus. We also found that the temporal variation in skin impedance locus, that is, the detail of the temporal variation in electrical properties, can be evaluated quantitatively by some of the skin impedance parameters estimated from impedance locus.
