Published:2011/9/8 6:16:00 Author:Ariel Wang | Keyword: acupoint detector

It is the acupoint detector circuit.The acupoint detector is made up by the detecting electrode A and B,multivibrator and acoustic-optic indicator. The oscillator composed of IC1,R8,R9 and C1 output the signal(square wave).The signal is controlled by the oscillator composed of IC2,R11,R12 and C3.Because the impedances in acupoint and non-acupoint act differently in human beings.The circuit converts the impendances to different potentials. The oscillation frequency of the oscillator emits different acoustic-optical signals.In this way,it realizes the acupoint detection.   (View)
