▎ 摘　　要

NOVELTY - The device has a graphene oxide film (10) and a first electrode (30) are bonded and packaged as a whole, and a second electrode (20) is placed on the other side of the graphene oxide film. The graphene oxide film and the second electrode are separated by an ion aqueous solution (50), and the graphene oxide film and the ion aqueous solution are used as a system to realize a PN junction effect. The ionic aqueous solution is a potassium chloride aqueous solution or an aqueous sodium chloride solution. USE - Device based on brine environment to achieve PN junction effect. ADVANTAGE - The device is built into the body as an electronic component, and the tissue fluid in the body is used as an aqueous ion solution to truly realize the integration of biomechanics and electromechanics. The preparation process is simple, does not involve toxic and harmful materials, and is suitable for use in fields such as biomedicine. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a semiconductor device. Graphene oxide film (10) Second electrode (20) Firts electrode (30) Ion aqueous solution (50)
