Resumen

The aim is to compare the mean values of the in vivo electrical characteristics of biological active points (BAPs) with those of the surrounding human skin. The impedance measurements at BAPs and on the surrounding skin are carried out in vivo on ten young, healthy people. The results of the measurements show that the BAP resistance R(P) is smaller, and the capacitance C(P) is higher, than the corresponding values for skin, R(S) and C(S), respectively, these differences are larger at low frequencies (at f=3Hz, R(S)/R(P)=3.19 and C(P)/C(S)=3.2). The mean values of the impedance measurements at the BAPs are different from those measured on the skin. The dependence of R(P) and C(P) on the pressing force, in the range of about 1-5 N, for the BAPs, has a smaller slope than that observed for the surrounding skin. An equivalent circuit for the BAPs is proposed that describes sufficiently well the experimental results obtained. These results show that the large dispersion in the observed impedance characteristics of the human body measurements in different body regions can be related to the influence of the BAPs present under the electrodes.
