Tyramine is generally produced via decarboxylation of tryptophan, and its long-term
exposure can induce severe symptoms in humans like brain stroke and hypertensive crisis …

High-toxicity secondary metabolites called aflatoxin are naturally produced by the fungus
Aspergillus. In a warm, humid climate, Aspergillus growth can be considerably accelerated …

Abstract The characteristics of Plastic Optical Fibers (POFs) are exploited to realize simple,
highly sensitive, and low-cost bio/chemical sensors via innovative schemes. The POF's …

Humidity measurement in biomedicals, industry and electronic manufacturing applications
needs an accurate and fast measurement of relative humidity by the sensor. In recent years …

This paper reports a flexible mechanical sensor developed by combining an opal photonic
crystal and a flexible medium through UV curing technology. Under the action of external …

An axial strain and temperature sensor based on tapered biased four-core fiber (BFCF)
operating at the dispersion turning point (DTP) is proposed. The non-adiabatic tapered …

In the past three decades, a wide range of sensing applications based on optical fiber
interferometric sensors have arisen. Wireless communication systems, satellite …

Optical fiber sensor operating at the dispersion turning point (DTP) has become a promising
building block for future development in biosensing application due to its ultrahigh …

A hybrid plasmonic waveguide Bragg grating (HPWBG) consisting of a polyvinyl alcohol
(PVA) microfiber coupled with metal strips oriented at right angles is reported for …

We propose and demonstrate a new temperature and curvature sensor based on double
peanut-shaped structures and tapered coreless fiber (CLF) using microfiber Mach-Zehnder …
