Ultrahigh sensitive detection of tau protein as Alzheimer's biomarker via microfluidics and nanofunctionalized optical fiber sensors
(Wiley, 2022)
Artículo / Artikulua,
Alzheimer’s disease (AD) is one of the most common neurodegenerative illnesses
displaying the highest death rate in the elderly. However, the existing AD
diagnostic system remains elusive due to lack of a technology that ...
Optical fiber refractometers based on sputtered indium tin oxide coatings
(IEEE, 2011)
Contribución a congreso / Biltzarrerako ekarpena,
This work presents the fabrication of optical fiber
refractometers based on indium tin oxide (ITO) coatings
deposited by sputtering with response in the visible spectral
region. ITO thin-films have been sputtered by ...
Gasohol quality control for real time applications by means of a multimode interference fiber sensor
(MDPI, 2014)
Artículo / Artikulua,
In this work we demonstrate efficient quality control of a variety of gasoline and ethanol (gasohol) blends using a multimode interference (MMI) fiber sensor. The operational principle relies on the fact that the addition ...
Development of a low mobility IEEE 802.15.4 compliant VANET system for urban environments
(MDPI, 2013)
Artículo / Artikulua,
The use of Vehicular Ad-Hoc Networks (VANETs) is growing nowadays and it includes both roadside-to-vehicle communication (RVC) and inter-vehicle communication (IVC). The purpose of VANETs is to exchange useful information ...
Analysis matrix for smart cities
(MDPI, 2014)
Artículo / Artikulua,
The current digital revolution has ignited the evolution of communications grids and the development of new schemes for productive systems. Traditional technologic scenarios have been challenged, and Smart Cities have ...
Optimized strain long-period fiber grating (LPFG) sensors operating at the dispersion turning point
(IEEE, 2018)
Artículo / Artikulua,
Two phenomena for enhancing the sensitivity of longperiod
fiber gratings are combined toward an increase of the sensitivity
to strain of this type of devices: the dispersion turning point
(DTP) and the cladding diameter ...
Optimization in nanocoated D-shaped optical fiber sensors
(Optical Society of America, 2017)
Artículo / Artikulua,
Nanocoated D-shaped optical fibers have been proven as effective sensors. Here,
we show that the full width at half minimum (FWHM) of lossy mode resonance can be
reduced by optimizing the nanocoating width, thickness and ...
Sensitivity enhancement experimental demonstration using a low cutoff wavelength SMS modified structure coated with a pH sensitive film
(Elsevier, 2018)
Artículo / Artikulua,
The multimode interference (MMI) effect in a single mode-multimode-single mode (SMS) can be used fordevelopment of wavelength shift detection based sensors. In this work, the focus is centered on obtainingwavelength shifts ...
Increasing the sensitivity of an optic level sensor with a wavelength and phase sensitive single-mode multimode single-mode (SMS) fiber structure
(IEEE, 2017)
Artículo / Artikulua,
The sensitivity of a liquid level sensor based on
a single-mode-multimode-single-mode fiber structure has been
increased by hydrofluoric acid etching. The etching process was
analyzed and monitored both theoretical and ...
Giant sensitivity of optical fiber sensors by means of lossy moderesonance
(Elsevier, 2016)
Artículo / Artikulua,
Here we show an optical refractometer with a giant sensitivity of 304,360 nm per refractive index unit(nm/RIU). This sensitivity corresponds to a resolution of 3.28 × 10−9RIU if a standard optical spectrumanalyzer with a ...
