▎ 摘　　要

NOVELTY - Method for preparing a semi-invasive brain-computer interface flexible electrode material with magnetron effect involves mixing poly(N-isopropylacrylamide-methacrylic acid) temperature-sensitive hydrogel precursor solution and ferrous ferric oxide-loaded-graphene oxide composite particles through physical mixing and gelating to obtain the product. USE - The method is useful for preparing a semi-invasive brain-computer interface flexible electrode material with magnetron effect. ADVANTAGE - The method solves the problems of low temporal and spatial resolution and small monitoring range caused by folds, entanglement, insufficient expansion and other reasons of the existing semi-invasive brain-computer interface electrode materials. The Brain-computer interface electrode material is safe and has high signal-to-noise ratio.
