▎ 摘　　要

NOVELTY - The device has a sensing unit provided with a single-mode optical fiber, a glass ferrule, a silver-doped two-dimensional molybdenum disulfide material and a carbon nano-tube. An inner surface of the single-mode optical fiber and a silicon film are formed with an air Fabry-Perot cavity. The silicon film is formed with a silicon Fabry-Perot cavity. A glass inserting core is fixed with the silver-doped two-dimensional molybdenum disulfide material and the carbon nano-tube. The glass ferrule is fixed with the silver-doped two-dimensional molybdenum disulfide material. USE - Lead ion/bacteria monitoring double-parameter optical fiber sensing device. ADVANTAGE - The device reduces the size of the sensing unit, increases the sensitivity of the sensing, reduces the cross influence of different parameters, and realizes the purpose of monitoring lead ion/bacteria at the same time. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for dual-parameter optical fiber sensor device for monitoring lead ions/bacteria and an implementation method. DESCRIPTION OF DRAWING(S) - The drawing shows a structural diagram of a dual-parameter optical fiber sensor device for monitoring lead ions/bacteria (Drawing includes non-English language text).
