▎ 摘　　要

NOVELTY - Rotating wheel disk type friction nano-generator comprises a stator (1) and a rotor (2). A friction layer film (3) is arranged between the stator and the rotor, and attached to the surface of the stator. The friction layer film is a polyvinylidene fluoride film containing graphene prepared by electrospinning. The rotor rotates relative to the stator under the action of an external force and generates friction with the friction layer film. The stator undergoes charge transfer under the action of the electric field generated by the friction, and realizing power generation. USE - The friction nano-generator is useful for sensing human joint movement. Can also be used in optical, thermodynamics, capacitor resistance characteristics magnetic field characteristics magnetic material and chemical characteristics of material. ADVANTAGE - The friction nano-generator has excellent power generation efficiency, and can be easily mounted on the joint. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of composition of the rotating wheel disc type friction nano-generator. 1Stator 2Rotor 3Friction layer film 4Load
