Fiber sensors possess characteristics such as compact structure, simplicity, electromagnetic
interference resistance, and reusability, making them widely applicable in various practical …

A high sensitivity optical fiber temperature and gas pressure sensor with integrated micro-
cavity is proposed. First, a single-mode optical fiber (SMF) is spliced with a section of …

We proposed and confirmed a highly sensitive gas pressure sensor based on a fiber Mach-
Zehnder interferometer, which uses polydimethylsiloxane (PDMS) and metal–organic …

In this paper, a temperature sensor based on fluorescence intensity ratio (FIR) technique is
prepared by the dual curing method. The pumping threshold is only 0.1 mW for the …

An integrated optical fiber sensor with high sensitivity and extremely low crosstalk was
theoretically and experimentally demonstrated for sensing temperature and pressure …

We present an optical fiber Fabry-Perot (FP) temperature sensor based on metal welding
technology. The fiber sensor is composed of a single-mode fiber and a metal capillary that …

The pressure and temperature of seawater are two important parameters. At present, people
mainly rely on various types of temperature and depth measurement instruments to monitor …

We use hollow core fiber (HCF) and single mode fiber (SMF) fusion splicing to form a sensor
with a “SMF-HCF-SMF” structure. To improve the sensitivity of the sensor, the HCF is tapered …

A novel hybrid interferometer sensor composed of a tapered seven-core fiber (TSCF) and a
polydimethylsiloxane (PDMS) cap at the end face of a TSCF is proposed for simultaneous …

In this manuscript, a temperature-insensitive U-shaped single-mode fiber (SMF) blood
glucose concentration sensor is proposed. A balloon-shaped SMF is first burned by a flame …
