    • Sensitivity improvement of a humidity sensor based on silica nanospheres on a long-period fiber grating 

      Viegas, Diana; Goicoechea Fernández, Javier Upna Orcid; Santos, José Luís; Araújo, Francisco Moita; Ferreira, Luis Alberto; Arregui San Martín, Francisco Javier Upna Orcid; Matías Maestro, Ignacio Upna Orcid (MDPI, 2009)   Artículo / Artikulua  OpenAccess
      This work addresses a new configuration that improves the sensitivity of a humidity sensor based on a long-period fiber grating coated with a SiO(2)-nanospheres film. An intermediate higher refractive index overlay, ...

    • Silver nanoparticles loaded electrospun nanofibers for humidity optical fiber sensing 

      Urrutia Azcona, Aitor Upna Orcid; Rivero Fuente, Pedro J. Upna Orcid; Goicoechea Fernández, Javier Upna Orcid; Rodríguez, Yoany; Arregui San Martín, Francisco Javier Upna Orcid; Matías Maestro, Ignacio Upna Orcid (2012)   Contribución a congreso / Biltzarrerako ekarpena  OpenAccess
      In this work, a new optical device based on silver loaded electrospun nanofibers (ENFs) for measuring Relative Humidity is proposed. Fiber mats composed of poly(acrylic acid) and β-cyclodextrin were deposited onto an optical ...

    • Simultaneous measurement of humidity and temperature based on a partially coated optical fiber long period grating 

      Urrutia Azcona, Aitor Upna Orcid; Goicoechea Fernández, Javier Upna Orcid; Ricchiuti, Amelia L.; Barrera, D.; Arregui San Martín, Francisco Javier Upna Orcid (Elsevier, 2016)   Artículo / Artikulua  OpenAccess
      A humidity and temperature optical fiber sensor based on a long-period grating (LPG), which can provide simultaneous response to both magnitudes, is proposed and demonstrated via experiments. Previously, the LPG was fully ...

    • Study and optimization of self-assembled polymeric multilayer structures with neutral red for pH sensing applications 

      Goicoechea Fernández, Javier Upna Orcid; Arregui San Martín, Francisco Javier Upna Orcid; Corres Sanz, Jesús María Upna Orcid; Matías Maestro, Ignacio Upna Orcid (Hindawi / Wiley, 2008)   Artículo / Artikulua  OpenAccess
      The characterization of nanostructured thin films is critical in the design and fabrication of optical sensors. Particularly, this work is a detailed study of the properties of layer-by-layer electrostatic self-assembled ...

    • Vibration detection using optical fiber sensors 

      Rodríguez García, Yoany; Corres Sanz, Jesús María Upna Orcid; Goicoechea Fernández, Javier Upna Orcid (Hindawi, 2010)   Artículo / Artikulua  OpenAccess
      Condition monitoring of heavy electromechanical equipment is commonly accomplished in the industry using vibration analysis. Several techniques, mainly based on capacitive and piezoelectric accelerometers, have been applied ...
