Electrical resistance of skin was studied with the aid of a specially designed meter that compared the resistance per surface area of small skin points with that of the surrounding skin. In a systematic study of the hands, face and ears in five subjects low-resistance skin points were repeatedly found in characteristic loci, comparable in different individuals and symmetric about the body midline. The low-resistance skin points had diametres of 1.5 +/- 0.5 mm and their borders were abrupt. On the dry skin resistance values were around 10 kilo-ohms at the center of the points but around 3 mega-ohms in the surrounding skin. Voltages could also be recorded at these points, but they proved to be result of electrode polarization reflected at these points because of their low electrical resistance. The distribution of the low points in the hands, face and ears resembled that of classical acupuncture points.
借助一种专门设计的仪器研究皮肤电阻，该仪器可比较小面积皮肤点的单位表面积电阻与周围皮肤的电阻。在对五名受试者的手部、面部和耳部进行的系统研究中，反复在特征性位点发现低电阻皮肤点，这些位点在不同个体中具有可比性且关于身体中线对称。低电阻皮肤点的直径为1.5±0.5毫米，其边界清晰。在干性皮肤上，这些点的中心电阻值约为10千欧，但周围皮肤的电阻值约为3兆欧。在这些点也可记录到电压，但事实证明这是由于这些点电阻低而在其上反映出的电极极化结果。手部、面部和耳部低电阻点的分布类似于经典针灸穴位的分布。
