文摘

An optical fiber based sensor to sense the toxic gas, hydrogen sulphide, selectively, is discussed. This approach uses a combination of an optical interferometry technique along with nanomaterials for sensing. It uses PMMA in the composite which uses the chemical swelling property of the polymer and specific sensitivity of ZnO. The cross-sensitivity is also documented by using oxygen gas.
