The sensitivity of the hydrogen sensor was determined by the diameter and sensing length of the Pd-decorated PMMA microfiber. Thus, the hydrogen sensor showed a sensitivity of <inline-formula> <tex-math notation=\"LaTeX\">$4.5 \\times 10^{-4}$ </tex-math></inline-formula> nm/ppm for a microfiber having a diameter and a sensing length of 28 and <inline-formula> <tex-math notation=\"LaTeX\">$473~\\mu \\text{m}$ </tex-math></inline-formula>, respectively. The sensitivity was further increased up to <inline-formula> <tex-math notation=\"LaTeX\">$5.3\\times 10^{-4}$ </tex-math></inline-formula> nm/ppm by extending the sensing length of the microfiber to <inline-formula> <tex-math notation=\"LaTeX\">$728~\\mu \\text{m}$ </tex-math></inline-formula>. When comparing the hydrogen sensing characteristics of pure- and decorated-PMMA microfibers, a significant improvement in sensitivity was obtained for the modified material which was attributed to the
