Adaptive control method and device for deviation in skin electrical signal testing

The present invention relates to biomedical technology field of information processing, to provide an electrical signal to test the top side skin adaptive control method, comprising setting a reference voltage B, the test electrode in the human body; B under the action of the reference voltage, picked up by measuring electrodes electrically human skin signal a; a skin through electrical amplification circuit of the first stage, to obtain galvanic skin response signal amplified A1; A1 galvanic skin response signal after subtracting the reference voltage of the amplified voltage difference value B obtained C, the voltage difference C through the second stage amplifier circuit to obtain the voltage difference between the amplified C '; C to the voltage difference amplified' analog to digital conversion; if | C '|> threshold circuits V', then adjust by reference voltage B, so that | A1-B |
