[0040] Hydrogel is a polymer material that can form a three-dimensional network structure in water and can adsorb and retain water molecules. Hydrogel electrodes generally include a conductor (electrode) and a gel layer. Among them, the conductor is generally made of metal materials such as silver, and its main function is the electrical connection part, connecting the gel with the signal acquisition equipment to transmit the collected physiological electrical signals. The gel layer is the core of the hydrogel electrode, which is generally composed of a mixture of pure water and polymers and is formed through processes such as heating, cooling and curing. The main function of the gel layer is to absorb sweat and cell signals on the surface of the body to ensure the accuracy of signal transmission and detection. Conductive hydrogel has high conductivity, low skin contact impedance and high signal quality. The hydrogel itself has adhesion. On the one hand, it can be directly adhered to the electrode support to simplify the process; on the other hand, the electrode is directly adhered to the skin to reduce motion artifacts under friction conditions. Conductive hydrogel electrodes use the water molecules in their own materials to establish ion channels between the electrode and the skin, so that high acquisition accuracy similar to wet electrodes can be achieved, and they can also be used as easily as dry electrodes.

The physiological electrical signal information includes at least one of electromyographic signal information, electrocardiographic signal information, electroencephalographic signal information, and electrooculographic signal information.

[0043] The present disclosure provides a hydrogel electrode, comprising: the hydrogel electrode comprises at least one first protrusion, the first protrusion is used to pass through the hair area of ​​the target object to collect physiological electrical signal information of the target object.

In addition, the hydrogel body can be stably fixed on the base through the fixing member.

[0044] The embodiment of the present disclosure provides a possible implementation method, wherein the electrode includes an electrode sheet 31 and a protrusion 32 arranged on the electrode sheet;

[0047] Specifically, the hydrogel electrode further includes a metal snap button located in the second inner cavity; the metal snap button is connected to the electrode through the protrusion of the electrode. The hydrogel electrode can be detachably mounted on the physiological electrical signal acquisition device through the metal snap button to acquire physiological electrical signal information of the target object.
