▎ 摘　　要

NOVELTY - The sensor has multiple graphene heating assemblies (21) arranged on a substrate (1). A power supply unit (3) supplies electric power to the graphene heating assemblies. The graphene heating assemblies are provided with a electrode, which is electrically connected to the power supply unit. A graphene layer is electrically connected to the electrode. The graphene layer is separated from the substrate. A measuring unit (4) measures temperature in which adsorption reaction of object gas is made. The graphene layer is provided with an air stray-type graphene structure. USE - Gas sensor. ADVANTAGE - The sensor permits low size electricity in an air-stray type graphene so as to increase gas reaction when low power gas sensor can be implemented. The sensor includes the air stray-type graphene to organize array configuration in which heating temperature is differently gradient through structure control of the heating assembly, so that different reactivity about the object gas can be simultaneously extracted, thus increasing wafer level. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a gas method sensing. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic block diagram of a gas sensor.
