▎ 摘　　要

NOVELTY - The sensor has a laminated set of graphene layer and a charge medium layer. The charge medium layer is used for sensing the electric field and the electric field force is formed. The electric field force makes the resonance frequency of the graphene layer change. The charge medium layer has a first charge medium layer and a second charge medium layer which are laminated. The first charge medium layer is set on one side of the second charge medium layer far away from the graphene layer. A charge retention region is formed between the first charge dielectric layer and the second charge dielectric layer. USE - Graphene electric field sensor for life of people, production and scientific research. ADVANTAGE - The graphene has good resonance characteristics so that the measuring range of the graphene electric field sensor measuring electric field is wide, and the sensitivity is high. DESCRIPTION OF DRAWING(S) - The drawing shows a structure schematic diagram of a graphene electric field sensor. 100Stretching graphene layer 110Charge dielectric layer
