In this article, a newly developed reduced Graphene Oxide (rGO)–Titanium Dioxide (TiO 2)
coated on a Fiber Bragg grating (FBG) based sensor is presented for the detection of …

In this work, we proposed a long period fiber grating (LPFG) seawater salinity sensor based
on a bend insensitive single mode fiber (SMF). The average curvature sensitivity of LPFG in …

Due to the advantages of small size, high sensitivity, and strong anti-interference ability,
optical fiber sensors are widely used in gas detection. Meanwhile, concentration and …

This article presents a numerical and experimental analysis of the linear chirp types of
refractive index profile etched fiber Bragg grating (e-FBG) sensor for the first time. Prior study …

Variations of seawater salinity often cause ocean internal waves, water masses and
stratification, which affect the stability of the ocean environment. Therefore, the study of …

In situ monitoring for complex multiphysical field changes of underwater environment has
urgent need for the miniaturized integrated multifunctional sensor. We have proposed and …

A CO 2 laser-induced long-period fiber grating (LPFG) in the dispersion turning point (DTP)
has been proposed in this work, which has demonstrated the possibility of fabricating LPFG …

This paper presents machinery fault diagnosis in electric motors through mechanical
vibration monitoring. Using a commercial machinery fault simulator, two Fiber Bragg …

This paper introduces a nickel ion concentration sensor based on a cladding etched FBG
with Chitosan/Dimethylglyoxime (CS/DmgH 2) sensing structure. The etching process of the …

This work presents the results of the production and characterization of etched saturated
fiber Bragg gratings (ESFBGs) functionalized with gold nanoparticles (AuNPs) as a refractive …
