Through literature review of acupoint electric characteristic (AEC) detection, some problems in the traditional method of AEC detection were found. The major reasons were lack of distinguishing the relationship between the acupoint and "skin on the acupoint" in the electric characteristics, which can not solve those objective and subjective interferential factors in acupoint detection. Therefore, the traditional acupoint detection method is not stable, and its repeatability is no good. The conception to design the probe of acupoint characteristic detection is put forward, which can give a real time and dynamic detection for the electric characteristics of the acupoint's various anatomic layers. Meanwhile, the circumstance of the body tissue is relatively stable, so the detection method can avoid those interferential factors.
