Specifically, a wireless signal transmitter is arranged on the insulating base and is connected with the electromyography acquisition sheet through a line, the wireless signal transmitter is also in communication connection with a host outside the electrode, the electromyography acquisition sheet transmits the collected electromyography signals to a wireless signal transmitter through a line, and then the signals are transmitted to the host capable of receiving the signals from the wireless signal transmitter, so that a computing system on the host can conveniently analyze and compute the data of the electromyography signals.

Specifically, the adhesive layer is of a net structure, so that myoelectricity conduction and collection are facilitated.

Specifically, the viscose layer includes ordinary viscose layer and epoxy viscose layer, and wherein ordinary viscose layer and insulating base bonding, the epoxy viscose layer sets up in ordinary viscose layer top, ordinary viscose layer can be vinyl acetate, polyvinyl alcohol, aquogel etc. and the epoxy viscose layer is nontoxic and the adhesion is strong, pastes fixed good and tear back no cull.

Specifically, the cleaning layer is the sponge that adsorbs saline, tears outer release film back, extrudees the sponge and makes saline, wipes facial position that detects, reduces impedance increase sensitivity.

Specifically, have four insulating pieces that are a style of calligraphy and arrange on the insulating base, two positive pole heads and two negative pole heads interval in proper order set up and the one-to-one inlays and locates in the recess on four insulating pieces.

The utility model has the beneficial effects that:

the linear surface nerve electrode provided by the utility model is simple and reasonable in structure and convenient to operate, the cleaning layer and the inner release film can be directly adhered to the electrode after being torn off, so that the operation is simpler and faster, and meanwhile, the problems of a Y-shaped patch and head band type detection mode in use do not exist.
