Ferrofluids are suspensions of magnetic nanoparticles that have the attractive feature of
being controlled by applied magnetic fields. Ferrofluids have been studied for decades in an …

Iron oxide nanoparticle (ION)-based ferro-nanofluids (FNs) have been used for different
technological applications owing to their excellent magneto-rheological properties. A …

The tunable refractive index of the magnetic fluid (MF) is a unique optical property, which
has attracted a lot of research interest in recent years. In this paper, a method based on the …

We experimentally demonstrated a strain sensor based on fiber ring cavity laser with a
photonic crystal fiber (PCF) in-line Mach-Zehnder interferometer (MZI) structure, which is …

We present a fiber optic magnetic field sensor conceived for magnetic resonance imaging
(MRI) applications. The sensor is based on the integration of fiber optic strain sensors (fiber …

A fiber ring laser based on a side-polish fiber Mach-Zehnder interferometer (MZI) for
effective improving refractive index (RI) and torsion sensing is proposed and investigated …

A compact all-fiber magnetic field sensor based on the magnetic gel coated hollow core fiber
(HCF) has been proposed and experimentally demonstrated. A double-layered Fabry–Perot …

In this paper, a ring fiber laser sensor based on a three layered-core few modes fiber (TL-
FMF) is proposed. The home-made TL-FMF is spliced with two pieces of single mode fiber …

Using the Fresnel reflection geometry and a fiber optic probe, a strong effect of interrogating
light intensity on an effective refractive index of ferrofluid placed in magnetic field was …

A new kind of photoelectric hybrid current sensor is designed. The low-power current
transformer (LPCT) is used as the primary sensor for current conversion. The optical fiber …
