▎ 摘　　要

NOVELTY - The flexible non-embedded brain-computer interface semi-dry electrode has a liquid storage tank (2) arranged inside a casing (1). The bottom end of the liquid storage tank is connected to a ball groove (14) through a liquid flow pipe (3). A first side of the middle of the liquid flow pipe is connected with a spring chamber (4). A connecting rod (9) is arranged in a connecting rod pipe (7). A first side of the connecting rod extends out of the casing, and a conical plug (6) is slidably arranged in the spring chamber. The balls are arranged in the ball groove. The bottom end of the ball and the bottom end of the electrode ring are in the same plane. USE - Flexible non-embedded brain-computer interface semi-dry electrode. ADVANTAGE - The electrolyte liquid is uniformly released through the ball during the use of the semi-dry electrode, so as to achieve a good effect of controlling the slow release of the electrolyte solution. The manufacturing process and production process of traditional semi-dry electrodes are simplified, and the manufacturing speed of semi-dry electrodes is improved on the premise of ensuring the quality of semi-dry electrodes. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing a flexible non-embedded brain-computer interface semi-dry electrode. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a flexible non-embedded brain-computer interface semi-dry electrode. 1Casing 2Liquid storage tank 3Liquid flow pipe 4Spring chamber 5Spring 6Conical plug 7Connecting rod pipe 8Piston 9Connecting rod 11Circuit board 14Ball groove
