▎ 摘　　要

NOVELTY - The sensor has a gas molecule adsorption system formed with surface plasma wave. A reflecting system generates a reflection material. A light intensity measuring system is output from a full-reflection system for reflecting the light. USE - Graphene gas sensor for low concentration gas molecule. ADVANTAGE - The sensor has high detection sensitivity, better stability, quick response speed, compact structure, simple structure and low cost. DESCRIPTION OF DRAWING(S) - The drawing shows a block diagram of a graphene gas sensor for low concentration gas molecule.'(Drawing includes non-English language text)'
