▎ 摘　　要

NOVELTY - The gas sensor has a sensing layer formed on three support bodies. The sensing layer includes dopamine formed on the fiber support. A graphene is combined with dopamine. The dopamine and graphene are hydrogen-bonded. The graphene is reduced graphene oxide after combining with the dopamine in form of graphene oxide. The nitrogen dioxide is sensed by a change in the conductivity of the graphene according to the contact between the nitrogen dioxide and the graphene. USE - Dopamine-graphene hybrid wearable electronic fiber-based gas sensor, particularly nitrogen dioxide sensor (Claimed) for detecting nitrogen dioxide gas. ADVANTAGE - The dopamine-graphene hybrid wearable electronic fiber-based gas sensor ensures efficient and quick detection of nitrogen dioxide gas with high sensitivity and high selectivity regardless of humidity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a manufacturing method for a dopamine-graphene hybrid wearable electronic fiber-based gas sensor. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic representation of a dopamine-graphene hybrid electronic fiber-based nitrogen dioxide gas sensor manufacturing method.
