[0031] In order to better understand the present invention, the surface EMG electrode with amplification function of the present invention will be described in detail below by way of examples. Those skilled in the art should understand that this does not constitute a limitation to the implementation of the invention claimed in this application.
[0032] The system structure system block diagram of the surface EMG electrode of the present invention is as follows figure 1 Shown. The surface EMG electrode mainly includes a signal acquisition unit, a signal filtering unit, a signal amplification unit and a signal output unit. The Ag / AgCL surface EMG electrode is used to draw the surface EMG signal from the human body, and then the signal is introduced into the amplifier with preliminary signal processing function. The physical space distance of the first-stage signal processing is reduced to reduce the influence of various interference signals introduced by long cable transmission f...
