▎ 摘 要
NOVELTY - Sensor (1) comprises a graphene film (21) having an opening, where opening has a zigzag edge or an armchair edge, and two electrodes which are electrically contacted with the graphene film for reading a change in electric characteristics of the graphene film due to co-action with an object to be detected. USE - Sensor. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of sensor. Sensor (1) Substrate (11) Foundation film (12) Graphene film (21) First electrode (51)
