      A first approach study for the classification of alfalfa (medicago sativa) quality has been performed by means of VIS-NIR optical fiber reflection spectroscopy. Reflection spectral data has been obtained from alfalfa samples ...
    • Copper oxide coated D-shaped optical fibers for the development of LMR refractometers 

      Ozcariz Celaya, Aritz Upna Orcid; Vitoria Pascual, Ignacio Upna Orcid; Arregui San Martín, Francisco Javier Upna Orcid; Ruiz Zamarreño, Carlos Upna Orcid (IEEE, 2020)   Contribución a congreso / Biltzarrerako ekarpena  OpenAccess
      Lossy mode resonance (LMR) based refractometers obtained by means of copper oxide thin-films fabricated onto side-polished (D-shaped) are presented in this work. The high refractive index of copper oxide combined with the ...
    • Micro sized interdigital capacitor for gases detection based on graphene oxide coating 

      Vitoria Pascual, Ignacio Upna Orcid; Armas, Dayron; Coronel Camones, Carlos Manuel; Algarra González, Manuel; Ruiz Zamarreño, Carlos Upna Orcid; Matías Maestro, Ignacio Upna Orcid; Mukhopadhyay, Subhas C. (Springer, 2023)   Contribución a congreso / Biltzarrerako ekarpena  OpenAccess
      A micro sized interdigital capacitor sensible to CO2 and NO is studied in this work. The photolithography technique enables to obtain fingers with dimensions of 10 × 500 µm and separated 7 µm between them. The deposition ...
    • Micro sized interdigital capacitor for humidity detection based on agarose coating 

      Vitoria Pascual, Ignacio Upna Orcid; Armas, Dayron; Coronel Camones, Carlos Manuel; Ozcariz Celaya, Aritz Upna Orcid; Ruiz Zamarreño, Carlos Upna Orcid; Matías Maestro, Ignacio Upna Orcid (2021)   Contribución a congreso / Biltzarrerako ekarpena  OpenAccess
      A micro sized interdigital capacitor has been proposed for the detection of relative humidity. The photolithography technique enables the fabrication of fingers with a size of 10x500 um. A thin film of agarose functionalizes ...
    • A technology review and field testing of a soil water quality monitoring system 

      Afridi, Waqas A. K.; Akhter, Fowzia; Vitoria Pascual, Ignacio Upna Orcid; Mukhopadhyay, Subhas C. (Springer, 2023)   Contribución a congreso / Biltzarrerako ekarpena  OpenAccess
      Soil water quality is one of the most influential factors in ensuring the productivity of agricultural farms. Soil water quality and soil quality are hugely dependent on each other. Hence, it is essential to have a clear ...
