Parameters Instantaneous Measurement of Electrical in a Palm During Electrodermal Activity

and obtain frequency characteristics of the skin impedance during thlc activity. However, no measurement systems for this technique have been developed. In this paper, we confirm that the principle of time-domain analysis can also be applied to skin impedance which varies with time. We have determined that the conditions present in the skin allow the use of this measurement method, and by so doing, a measurement system which can determine skin impedance instantly has been developed. The efficiency of this system is shown by its capacity to obtain the time course of the impedance locus.
