COMPUTERIZED PLOTTING OF LOW SKIN IMPEDANCE POINTS
摘要
The distribution of low skin impedance points(LSIP)was studied on 68 subjects with a computersystem designed for the measurement of skin impedance.The results demonstrated that LSIPswere basically distributed along the 14 channels,the overwhelming majority located right on orwithin 5 mm bilaterally to their courses.LSIPs were found in the area between every two chan-nels only in a few cases.Moreover,there was no marked natural fluctuation of skin impedance inthe human body and the distribution of LSIPs was considerably stable,which could be plotted onany day in the experiment.It is clear that such particular distribution of LSIPs along channelswas really a biological phenomenon,not an experimental error.However,the distribution of lowskin impedance was not an uninterrupted solid line but a series of LSIPs basically along thechannel course.The method used in this work was accurate,reliable and repeatable which hasupgraded the measurement of LSIPs to a new level.Under certain conditions,skin impedancecan be used as an objective index in channel research.
