▎ 摘　　要

NOVELTY - The electrode comprises a base portion and an electrode claw portion. The semi-dry electrodes are prepared by using acid treatment of graphene and polyvinyl alcohol (PVA), propylene glycol, propylene ethylene glyco, ferric chloride and water gelation. USE - Semi-dry electrode for collecting electrooculoelectric signal with elasticity used in wearable electronic field. Uses include but are not limited to sleep mode, brain condition, somnolence and eye fatigue, and man-machine interaction of disorders and disorders e.g. hyperactivity disorder, stroke, autism and Alzheimer's disease and Parkinson's disease. ADVANTAGE - The semi-dry electrode has elasticity, good weather resistance, good conductivity, comfortable wearing, and simple preparation. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for preparing a semi-dry electrode. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a semi-dry electrode.
