The invention discloses a wearable device for EEG monitoring, which includes a mounting frame, a first brain electrode and a second brain electrode, and the mounting frame includes a first horizontal guide rail, a second horizontal guide rail, a third horizontal guide rail, a top plate, a second A connecting arm and a second connecting arm, the first horizontal guide rail and the second horizontal guide rail are ring structures, the third horizontal guide rail is a C-shaped structure, and the first horizontal guide rail, the second horizontal guide rail, the third horizontal guide rail The horizontal guide rails are concentrically arranged directly under the top plate in turn. This wearable device for EEG monitoring can place brain electrodes at any position on the human head, so that when the brain electrodes act on patients with different head shapes, the position is more accurate, and it can Adjust the distance between the brain electrode and the patient's head, so that the brain electrode can be in close contact with any position of the head, preventing the brain electrode from falling off, and also preventing the brain electrode from being in poor contact, improving the stability of the brain wave data .
