Electrical Conductivity of Human Skin: Some Metrological Aspects
The article is devoted to the metrological aspects of measuring the electrical conductivity of human skin. These measurements are an integral part of a number of functional diagnostics techniques: electroencephalography, electrophthalmography, electromyography etc. In electropuncture diagnostics, based on a comparison of electrical conductivity at individual acupuncture points with the average for all measured points, the formulation and the nature of the operation on the body are selected. With various methods of electrical stimulation of organs, the effectiveness of the operation depends on the electrical conductivity of the skin. However, until now, there are no generally accepted points of view on the parameters of measuring circuits and the applicability of electrodes made of different materials in the measurement procedure. Since we were unable to find a systematic presentation on this issue in the available sources, we undertook a large study, the first report of which is presented in this article. Β© 2021 IEEE

This article is devoted to the study of some methodological and metrological aspects of measuring the electrical conductivity of human skin for diagnostic purposes. Over the past four decades, reflex therapists in many countries have been using various methods and devices of electropuncture diagnostics to determine the prescription and the type of exposure to the patient. At first, these were analog devices that did not allow assessing the influence of the measuring circuits components on the measurement results. Following the advent of technologies for digitizing the measurement process and digital processing of measured values time series, it became possible to determine the optimal parameters of measurement techniques, to link the measured parameters with the processes taking place in the human body, and to create adequate mathematical models. Since we were unable to find a systematic presentation on this issue in the available sources, we undertook a large study, the first report of which is presented in this article.ΠΡΠ° ΡΡΠ°ΡΡΡ ΠΏΠΎΡΠ²ΡΡΠ΅Π½Π° ΠΈΡΡΠ»Π΅Π΄ΠΎΠ²Π°Π½ΠΈΡ Π½Π΅ΠΊΠΎΡΠΎΡΡΡ
