title = "Humidity sensor based on a long-period fiber grating coated with a hydrophobic thin film",
abstract = "In this work it is proposed a novel fiber optic humidity sensor based on a functionally coated long-period fiber grating (LPG). The coating is composed of tetraorthosilicate matrix functionalized with perfluorooctyltriethoxysilane and its fabrication was performed by the sol-gel technique using a dip coating process using the LPG as substrate. This technique allows to fabricate sensitive films in a fast and simple way compared to other overlay fabrication techniques. The fabricated sensor was tested in a programmable temperature and climatic chamber. Relative humidity (RH) was varied in range from 20\%RH to 80\%RH at room temperature. The results showed a smooth exponential-like wavelength shift of the LPG attenuation band.",
