“…Comparing to previous study [7], this sensor gives a higher sensitivity and could be used in hostile environments. Essentially, FBG possesses the advantages of electrical passivity and hence immunity to electromagnetic interference, they are also corrosion resistant, have a wide operating temperature [8]- [9] and superior multiplexing capabilities over long distances. These features render FBG a good alternative sensing element for applications under extreme environmental conditions.…”

“…However, electronic devices cannot be utilized in rigorous environments, such as in the existence of corrosive substances, at extremely low or high temperature, and in chemical environments. In this regard, substantial attention has been paid to temperature sensor research because of the vigorous usage of such sensors in the aforementioned fields over the last few decades [1,2].…”

The exploration of novel polymers for temperature sensing with high sensitivity has attracted tremendous research interest. Hence, we report a polystyrene-coated optical fiber temperature sensor with high sensitivity. To enhance the temperature sensitivity, flat, thin, smooth, and air bubble-free polystyrene was coated on the edge surface of a single-mode optical fiber, where the coating thickness was varied based on the solution concentration. Three thicknesses of the polystyrene layer were obtained as 2.0, 4.1, and 8.0 μm. The temperature sensor with 2.0 μm thick polystyrene exhibited the highest temperature sensitivity of 439.89 pm °C−1 in the temperature range of 25–100 °C. This could be attributed to the very uniform and thin coating of polystyrene, along with the reasonable coefficient of thermal expansion and thermo-optic coefficient of polystyrene. Overall, the experimental results proved the effectiveness of the proposed polystyrene-coated temperature sensor for accurate temperature measurement.

“…Optical fiber sensors based on Raman scattering [ 9 , 10 , 11 , 12 , 13 , 14 , 15 ], Brillouin [ 16 , 17 ], and fiber Bragg grating [ 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 , 30 , 31 , 32 ] are three common ways to realize multipoint measurement. Rusen Yan et al [ 9 ] reported a temperature-dependent Raman sensor, and the temperature sensitivities are −0.011 cm −1 /K and −0.013 cm −1 /K for different modes in the range from 100 K to 320 K, respectively.…”

A temperature multipoint sensing system based on three cascade Mach–Zehnder interferometers (MZIs) is introduced. The MZIs with different lengths are fabricated based on waist-enlarged fiber bitapers. The fast Fourier transformation is applied to the overlapping transmission spectrum and the corresponding interference spectra can be obtained via the cascaded frequency spectrum based on the inverse Fourier transformation. By analyzing the drift of interference spectra, the temperature response sensitivities of 0.063 nm/°C, 0.071 nm/°C, and 0.059 nm/°C in different furnaces can be detected from room temperature up to 1000 °C, and the temperature response at different regions can be measured through the sensitivity matrix equation. These results demonstrate feasibility of multipoint measurement, which also support that the temperature sensing system provides new solution to the MZI cascade problem.
