Wearable brain electrode

The invention belongs to the technical field of brain electrodes, and relates to a wearable brain electrode which is provided with a multi-claw structure and a multi-claw structure mounting part. The multi-claw structure comprises a plurality of claw units; one ends of the plurality of claw units are annularly distributed on the periphery of the multi-claw structure mounting part; each claw unit comprises a lining layer, a conductive layer, an elastic component and a surface layer; an inner cavity is formed between the lining layer and the surface layer, and the lining layer is in a stretched state when the head is worn in the inner cavity; a plurality of spherical mounting holes are distributed in the lining layer; the conductive layer is located in the inner cavity; the conductive layer comprises a signal transmission part and a conductive ball. And an elastic multi-claw structure is adopted, so that each detection electrode can be effectively ensured to be tightly attached to a detection site, and the dete
