The development of reliable, affordable and efficient sensors is a key step in providing tools
for efficient monitoring of critical environmental parameters. This review focuses on the use …

Optical microfiber-based temperature sensors have been proposed for many applications in
a variety of industrial uses, including biomedical, geological, automotive, and defense …

The development of a highly sensitive ammonia sensor is described. The sensor is formed
by deposition of a nanoscale coating of titanium dioxide, containing a porphyrin as a …

We demonstrated a simple technique for a highly sensitive temperature sensor based on an
“S”-shape fiber taper Mach-Zehnder interferometer (MZI) with no need of special fibers or …

Due to the exotic electronic and optical properties, two-dimensional (2D) materials, such as
graphene, topological insulators, transition metal dichalcogenides, black phosphorus …

We proposed a polyaniline-camphorsulfonic acid/titanium dioxide (PANI-CSA/TiO 2) coated
glass capillary tube sensor structure in this work. The PANI-CSA/TiO 2 sensitive material …

We present a highly reproducible method of fabricating a tapered intrinsic Fabry–Perot
interferometer (IFPI) device with 5–6 diameter at the taper waist. A femtosecond laser was …

In this paper, the concept, analysis, and synthesis of a novel plasmonic leaky wave antenna
(LWA) based on the modulated radius of a cylindrical graphene waveguide (CGW) at the …

Waveguide imaging is considered as one of the most important and widely used techniques
in biomedical endoscopic applications. Recently, many attempts have been made to …

The development of an ammonia sensor, formed by the deposition of a functionalised
titanium dioxide film onto a tapered optical fibre is presented. The titanium dioxide coating …
