Stretchable high-density myoelectric signal electrode slice based on hydrogel

Abstract

The invention discloses a stretchable high-density myoelectric signal electrode slice based on hydrogel, and relates to the field of biological myoelectricity. The electrode slice includes a basal layer, a sealing layer, a conductive electrode and a wire, and has a physical character of being completely transparent, wherein the basal layer and the sealing layer are made of polypropylene polymers, and the conducive electrode and the wire are made of the hydrogel. The hydrogel material is conducive and can be used for making electrodes and wires. The hydrogel electrode is an 8x8 array and belongs to a transparent colloidal material. One side of the hydrogel electrode is fixed to the basal layer, and the other side is not packaged but is used for touching the skin. The hydrogel wire and the electrode are made of the same material, one end of the hydrogel wire is connected to the hydrogel electrode, and the other end of the hydrogel wire is connected with an external electronic component. The hydrogel wire is sealed by the basal layer and the sealing layer for preventing the hydrogel wire from touching the skin during use. Compared with the prior art, the electrode slice is strong in stretchability, capable of avoiding malposition of measurement points of myoelectric signals during use, simple in structure and low in cost.

Description

technical field [0001] The invention relates to a technology in the field of biomyoelectricity, in particular to a stretchable high-density electromyographic signal electrode sheet based on hydrogel. Background technique [0002] Electromyographic signal (EMG) is a kind of bioelectrical signal, which is the superposition of action potentials of motor units in muscle fibers in time and space, and can reflect the movement state of nerves and muscles to a certain extent. At present, there are mainly two ways to use electromyographic signals. One is to insert a needle motor into the muscle to obtain electromyographic signals. This method has less interference and high signal recognition, but it will cause certain damage to the human body; The first method is to stick the electrode sheet on the skin surface. This method will not cause harm to the human body and is relatively simple. It is currently a more commonly used method for collecting EMG signals. However, when the muscle ...
