▎ 摘　　要

NOVELTY - A biosensor consists of a sensing unit (100) including a graphene layer (103), a bridge unit connected to the sensing unit, and an electrode unit connected to the bridge unit. USE - Biosensor e.g. humidity sensor, pH sensor, glucose sensor and strain gauge used in glucose control system (all claimed). ADVANTAGE - The biosensor has excellent reliability, and improved interfacial property, flexibility and elasticity, and can be easily fabricated. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) fabrication of the biosensor; (2) glucose control system; (3) fabrication of the glucose control system; and (4) method for controlling glucose. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a sensing unit of the biosensor.
