[0032] like Figure 2 , 3 As shown in Figures 4 and 5, the embodiment of the present disclosure provides a fabric electrode, comprising: 6 first protrusions 1, 1 second protrusion 2, and a circular process edge 6. 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. The physiological electrical signal information includes at least one of electromyographic signal information, electrocardiographic signal information, electroencephalographic signal information, and electrooculographic signal information.
[0033] The fabric electrode may be a silver electrode, or may be a conductive fabric electrode made of other materials that can collect electromyographic signals.
[0034] Specifically, the first protrusion and the second protrusion can be formed by hot pressing a conductive fabric layer 3 and a hot pressing conductive sponge layer 4 stacked from top to bottom through a hot pressing mold, and then filling the bottom of the electrode with a soft conductive sponge 5. The hot pressing conductive sponge layer 4 has a certain hardness, which can ensure that the first protrusion and the second protrusion can effectively penetrate the hair area, and the soft conductive sponge 5 can ensure the overall resilience. Poor resilience can be avoided, and the effective contact area with the human skin cannot be formed after being concave, so that the physiological electrical signal information cannot be effectively collected.
[0035] Specifically, the first protrusion and the second protrusion can be circular protrusions or other irregular protrusions; wherein the circular design can ensure that the protrusion has a certain resilience and forms an effective contact area with human skin. Specifically, a first protrusion is arranged at the center of the protrusion of the second protrusion, and 6 first protrusions are evenly arranged around the first protrusion arranged at the center of the protrusion of the second protrusion.

[0037] The embodiment of the present disclosure provides a possible implementation method, wherein a circular process edge 6 for heat pressing with the fabric is arranged around the second protrusion, and the diameter of the circular process edge is 18 to 22 mm.

Compared with the existing planar fabric electrode, the first protrusion and the second protrusion can effectively penetrate the hair, thereby forming effective contact with the skin of the hair area, and effectively collecting physiological electrical signal information of the hair area. In addition, the first protrusion is arranged on the second protrusion, and through the cooperation of the first protrusion and the second protrusion, a certain resilience can be guaranteed, so as to avoid the first protrusion being concave due to the contact pressure and failing to form an effective contact area with the hair area, thereby affecting the collection of physiological electrical signals.
