▎ 摘　　要

NOVELTY - The method involves processing the graphite into the graphene or derivative. The graphene or derivative is used as the gas sensitive unit of the sensor. Graphite substrate is used as the conductor of the current through the external circuit measuring graphene. The graphite plate is formed by graphite the block body. The size is generally a few square microns to tens of square centimeters. The graphene is generated on the surface changes the resistance of the graphite substrate. The resistance value is measured by the external electrode changes. USE - Method of using for high energy laser preparing graphene gas sensor. ADVANTAGE - Method provides easy to connect with the external circuit integrated in large scale integrated circuit in the consumer electronics. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a method of using for high energy laser preparing graphene gas sensor.
