Electrical Characteristics of Biological Active Point from Three Electrode Method

Abstract

We anticipate the development of new real time biological active point (BAP) systems based on skin impedance, since this measurement method has the superior characteristics of noninvasiveness and easy operation. In this paper, we report on the three electrode measure method that has the advantage of measuring the impedance of the BAPs under the skin. This system easily measured the potential difference between the measurement electrodes and reference electrodes. The BAPs have lower impedance at all frequencies and their reactance is much smaller than that of the surrounding skin. The characteristic frequencies of BAPs are about 20-30HZ higher than that of the surrounding skin. This technology analyzed accurately and objectively the reactance and characteristic frequency of BAPs.
