TL;DR: In this paper, a high sensitivity RH sensor based on an agarose-doped poly Methyl Methacrylate (PMMA) sensor head is demonstrated, which can achieve power variation of up to 2.9 μW in a wide relative humidity range (50-80%).

TL;DR: An ammonia sensor composed of a tapered multimode fiber coated with polyaniline nanofibers that operates at room temperature (26°C) and the highest sensitivity is achieved when the diameter is reduced to 20 µm.

TL;DR: A Mach-Zehnder interferometric magnetic field sensor based on a photonic crystal fiber (PCF) and magnetic fluid (MF) was designed and experimentally demonstrated and the sensitivity and transmission spectra of the proposed sensor under different magnetic field intensities have been measured and theoretically analyzed.

TL;DR: In this article, a high sensitivity pressure sensor without a polymer transducer is demonstrated, which has a sensitivity of 0.0115 nm/psi and provides accurate measurement of the pressure and shows good repeatability.

TL;DR: In this article, the authors present an overview of most of the Erbium-doped fiber amplifier (EDFA) configurations that have been proposed in order to provide the researchers with a clear view of what has been done in this field.
