▎ 摘　　要

NOVELTY - The method involves providing a graphite cylinder in contact with a peeling mechanism (20), and a graphite layer is formed on the peeling mechanism. Multiple peeling mechanisms are contacted and separated in sequence, and a sensor base housing is provided in contact with the last peeling mechanism. A graphene layer is formed on the sensor substrate. A graphene-based high-sensitivity hydrogen sensor preparation device is used. The device is provided with a traverse mechanism (10), a peeling mechanism, a feeding mechanism (50) and a material changing mechanism (60). Multiple peeling mechanisms are connected to the traverse mechanism. USE - Method for preparing graphene-based high-sensitivity hydrogen sensor (claimed) used in temperature compensation system. ADVANTAGE - The graphene-based high-sensitivity hydrogen sensor provides high sensitivity, and can prepare the sensor substrate taking graphene as substrate surface layer. The graphene layer is formed on the graphene layer lead-out electrode of the sensor base housing, so that the hydrogen sensor is used as a hydrogen sensor with high sensitivity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a graphene-based highly sensitive hydrogen sensor. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of a graphene-based highly sensitive hydrogen sensor manufacturing apparatus.
