Journal ArticleDOI
Agarose optical fibre humidity sensor based on electromagnetic resonance in the infra‐red region
Miguel Hernaez,Carlos R. Zamarreño,Carlos Fernández-Valdivielso,Ignacio Del Villar,Francisco J. Arregui,Ignacio R. Matias +5 more
TL;DR: In this paper, an optical fiber humidity sensor based on electromagnetic resonances (EMR) is presented, which works as a refractometer whose EMR absorption peak shifts when the refractive index of the surrounding medium varies.
Proceedings ArticleDOI
Experimental design rules for implementing biconically tapered single mode optical fibre displacement sensors
TL;DR: Tapered optical fibres are used to design couplers, wavelength division multiplexers, near field scanning optical microscopy [2] and to sense distinct parameters such as temperature, humidity, PH, etc as mentioned in this paper.
Journal ArticleDOI
Development of a Low Mobility IEEE 802.15.4 Compliant VANET System for Urban Environments
TL;DR: Simulation-based values of the estimated signal strength and radio link quality values are obtained and compared with measurements in outdoor conditions to validate an implemented VANET system and confirm the possibility of implementing low cost vehicular communication networks operating at moderate vehicular speeds.
Journal ArticleDOI
Increasing the Sensitivity of an Optic Level Sensor With a Wavelength and Phase Sensitive Single-Mode Multimode Single-Mode Fiber Structure
Omar Fuentes,Ignacio Del Villar,Jose R. Vento,Abian B. Socorro,Elieser E. Gallego,Jesus M. Corres,Ignacio R. Matias +6 more
TL;DR: In this article, the sensitivity of a liquid level sensor based on a singlemode-multimode-singlemode fiber structure has been increased by hydrofluoric acid etching.
Journal ArticleDOI
Generation of Lossy Mode Resonances in Planar Waveguides Toward Development of Humidity Sensors
TL;DR: In this article, a new setup is explored, based on the lateral incidence of light on conventional planar waveguides such as glass slides or coverslips, which can generate Lossy mode resonances with angles approaching grazing incidence.
