▎ 摘　　要

NOVELTY - Non-invasive electroencephalogram sensor based on flexible substrate comprises a flexible substrate and a reducing graphene oxide, where the reducing the graphene oxide is deposited on the flexible substrate by soaking and drying. USE - The non-invasive electroencephalogram sensor for converting ion current into an electronic current available in a conductor for monitoring brain wave, and package transportation, biological medicine, heat preservation material and building engineering. ADVANTAGE - The non-invasive electroencephalogram sensor has good conductivity, low skin impedance, and scalp has good contact property, and can effectively monitor brain wave. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a preparation method of the non-invasive electroencephalogram sensor based on flexible substrate. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of the combination of the conductive sponge and the electrode slot prepared by the impregnation method.
