▎ 摘　　要

NOVELTY - The electrode has a flexible electrode shell (1) for supporting. A flexible gel (5) obtains a bio-electrical signal with skin contact. The flexible gel is adhered to an inner portion of the flexible electrode shell. A conductive cloth (2) i.e. silver-plated conductive cloth, derives electronic current. The flexible gel contacts the conductive cloth placed in the flexible electrode shell. A flexible conductive wire (4) conducts the electronic current from the conductive cloth to an external electroencephalogram device. An end of the flexible conductive wire is connected with the conductive cloth. Another end of the flexible conductive wire is connected with the external electroencephalogram device. The flexible gel is made of hydrogel or gelatin material. The flexible electrode shell is selected from one of polydimethylsiloxane, ecoflex and silbione materials. The flexible conductive wire is sleeted from one of silver-plated wire, carbon fibre and conductive nylon materials. USE - Fully flexible electrode for electroencephalogram collection and preparation of graphene/graphene oxide dry electrode used in a field of a brain-computer interface (BCI). ADVANTAGE - The electrode does not need conductive paste, when using, and has simple operation, strong flexibility, better moisturizing ability, high degree of skin, and low impedance contact. The electrode has high comfort level suitable for neonatal use, and existence of a micro-column, and can effectively improve degree of microcosmic and skin. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a preparation method for a full flexible electrode for electroencephalogram collection. DESCRIPTION OF DRAWING(S) - The drawing shows a structure schematic diagram of the fully flexible electrode for electroencephalogram acquisition. 1Flexible electrode shell 2Conductive cloth 3Insulating layer 4Flexible conductive wire 5Flexible gel
