▎ 摘　　要

NOVELTY - The unit has a graphene array provided on a surface of a spacecraft through an insulator layer for measuring resistance value of the graphene array in a space environment and surface potential of a spacecraft to obtain distribution condition of a spacecraft potential surface. The graphene array is arranged into multiple graphene potentiometer detectors that are provided with a graphene detection layer and the insulating layer. The graphene array is used for detecting multidimensional vector and omnidirectional detection vector through multiple layers. USE - Unit for measuring spacecraft surface potential by using graphene. ADVANTAGE - The unit is simple in structure and convenient to use, and reduces interference, requires less occupation space, and rapidly realizes multidimensional vector detection operation and multi-point or even omnidirectional detection operation. DESCRIPTION OF DRAWING(S) - The drawing shows a graph view representing a relationship between a spacecraft surface potential resistance value and a multidimensional vector related to a unit for measuring spacecraft surface potential by using graphene.
