▎ 摘　　要

NOVELTY - Synthesis of graphene involves annealing a substrate in a hydrogen gas atmosphere, subsequently undertaking a deposition and nucleation step in which a relatively thick carbon layer is deposited onto the substrate and subsequently thinned to form small graphene islands or nuclei, undertaking a graphene growth step in which the graphene islands or nuclei expand and coalesce, and subsequently allowing the substrate to cool. USE - The method is useful for synthesizing graphene used for fabricating graphene based sensor (all claimed). ADVANTAGE - The method permits the synthesis of relatively large dimension graphene sheets. The fabricated sensor may be of flexible and transparent form, providing a good level of sensitivity to touch inputs and a fast response time. Fabrication is relatively quick and simple, thus the sensors may be fabricated in an economic manner. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a graphene based sensor (10) comprising at least one graphene sheet synthesized using the method above. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the sensor. Sensor (10) Strips (12a, 14a) Electrical contact (16) Capacitor regions (20)
