Paper Abstract
This work addresses a humidity sensor using long-period fiber gratings (LPG) coated with silica nanospheres film. SiO2-nanospheres coating is deposited onto the LPG using the electrostatic self-assembly technique (ESA). The polymeric
overlay changes its optical properties when exposed to different humidity levels, resulting in a shift of the resonance
wavelength of the LPG. The obtained results are accordant with the theoretical simulations. Wavelength shifts up to
12nm in a humidity range from 20% to 80% are reported, maintaining the same dependence at different temperatures.
