▎ 摘　　要

NOVELTY - The method involves fixing multiple electrodes in a graphene oxide film. Graphene oxidation reduction process is performed to form a reduced oxidation graphene film for manufacturing an air flow sensor. The graphene oxide film is formed on a substrate through a physical adsorption and/or covalent bond way, where thickness of the graphene oxide film is 1 nm- 40 nm. The graphene oxide film is formed with a metal layer by performing thermal evaporation process. A silicon sheet is formed with a silicon dioxide layer. The silicon sheet is selected as the substrate. USE - Graphene oxide-based air flow sensor manufacturing method. ADVANTAGE - The method enables simplifying air flow sensor structure with high sensitivity, miniaturizing size of the air flow sensor, detecting weak air stream conditioned level and improving weak air stream processing convenience with low cost. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for the following: (1) a graphene oxide-based flow sensor (2) an air flow testing system (3) an air flow testing method. DESCRIPTION OF DRAWING(S) - The drawing shows a sectional view of an air flow sensor.
