(2012) Humidity sensor based on silver nanopartlcles embedded in a polymeric coating. International Journal On Smart Sensing and Intelligent Systems, 5(1), 71-831178-5608https://academica-e.unavarra.es/handle/2454/48209In this work, it is presented a novel optical fiber humidity sensor based on silver nanoparticle-loaded polymeric coatings built onto an optical fiber core. The polymeric film was fabricated using the Layer-by-Layer assembly technique. The silver nanoparticles (Ag NPs) were characterized using transmission electron microscopy (TEM and UV-VIS spectroscopy. A Localized Surface Plasmon Resonance (LSPR) attenuation band is observed when the thickness of the coating increases, and showed a very good sensitivity to Relative Humidity (RH) variations, suitable for high performance applications such as human breathing monitoring.application/pdfengCreative Commons BY-NC-ND 4.0 Attribution-NonCommercial-NoDerivs 4.0 InternationalOptical fiberHumidity sensorSurface plasmon resonance (SPR)Synthesis of silver nanoparticlesPolymeric coatingArtículo / Artikulua2024-05-28Acceso abierto / Sarbide irekiainfo:eu-repo/semantics/openAccess
