▎ 摘　　要

NOVELTY - The detector has a macroscopic graphene film (2) arranged on an upper surface of a flexible dielectric substrate (3). The macroscopic graphene film and the flexible dielectric substrate form a macroscopic graphene conformal micro-strip antenna. A lower surface of the flexible dielectric substrate is adhered on an outer surface of a to-be-measured metal structure. The macroscopic graphene conformal micro-strip antenna is externally connected with a wired detection device. The wired detection device detects resonant frequency of the macroscopic graphene conformal micro-strip antenna. USE - Macroscopic graphene conformal micro-strip antenna metal crack detector. ADVANTAGE - The detector can realize real time detection of whether a complex curved surface metal structure has crack, and can realize detection of crack length and direction. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a macroscopic graphene conformal micro-strip antenna metal crack detecting method. DESCRIPTION OF DRAWING(S) - The drawing shows a top perspective view of a macroscopic graphene conformal micro-strip antenna metal crack detector.
