▎ 摘　　要

NOVELTY - The film has a graphene heating-out electrode (3) provided with a net-shaped structure graphene film, where sides of the graphene heating layer as a heating film electrode (4) is used for connecting an external power supply. A mesh structure is formed by a transverse graphene and longitudinal strips graphene, where a transverse strip and a longitudinal strip are vertical or not vertical, longitudinal strips at ends are led out as the heating electrode and a strip constituting the mesh structure is a linear type and a curved line type. The mesh structure is formed by integrally processing the graphene film. USE - Graphene heating film based on net-like structure. ADVANTAGE - The film can be greatly improved stability of a film structure graphene heating such that temperature uniformity of a graphene heating and a temperature monitoring are more convenient and more accurate, thus ensuring reliability of the film when working. The film facilitates a distribution condition of the longitudinal strip of a net graphene heating, thus improving a heating degree and improving user experience. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a wearable device. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a graphene heating film based on net-like structure.
