THE INFLUENCE OF THE SKIN FATIGUE, ITS PERSPIRATION AND THE TIME OF STIMULATION IN MEASUREMENT OF THE ACTIVE POINTS ON HUMAN SKIN

Our contribution deals with the human skin voltage chart measurement. The human skin has a certain impedance or resistance - it can be relatively easily described and simulated using a substitute electric circuit. But the skin also contains parts with measurably lower impedance and different electric properties – we can show them clearly by measurement of voltage chart. We have concentrated our effort on finding and following measurements of active points on certain part of the skin's surface, to acknowledge their existence and positions through a measuring process. The parameters of the measured voltage chart are influenced by the amplitude, frequency, the shape of the measuring electric signal and the parameters of skin-electrode connection changing in time. We focused our research effort in this paper to measure the influence of the time of external stimulation, irritation and a contact press on skin surface together with the skin fatigue and perspiration effects
