Study on DC resistance and AC steady-state characteristics of the Pericardium Meridian on skin surface

Although acupuncture is studied by lots of scientists all over the world, the mechanism of its function is not clear yet. This paper describes the research history of Chinese meridian theory first. Then the method of electronic information science is applied to study the specificity of the signal transmission along human Pericardium Meridian. Certain points on the Pericardium are selected, and a special electrode array is implemented to study the resistance and the AC steady-state characteristics. Furthermore, digital signal processing methods are used to analyze the waveform to compare the spectrum of the signal of meridian and non-meridian under the same stimulating. The conclusion and prospect will be presented in the end of this paper.
