“…Temperature Sensing structural health monitoring [51], nuclear industry [52], electric power systems [53], and so on. But in most applications, the cross-sensitivity problem of temperature and strain of FBG sensors is urgently needed to solve, and this research was also conducted extensively [54][55][56][57].…”

Temperature is an important physical quantity in most industrial processes. Distributed temperature sensor (DTS), fiber Bragg grating (FBG), and tunable diode laser absorption spectroscopy (TDLAS) are three primary techniques for temperature measurement using fiber optic sensing and spectrum technology. The DTS system can monitor space temperature field along the fiber in real time. In addition, it also can locate a fire source using two sections of optical fibers which are placed orthogonally to each other. The FBG temperature sensor is used to measure the point temperature. The temperature sensitivity of the bare FBG is 10.68 pm/ C and the linearity is 0.99954 in the range of 30-100 C. Based on tunable diode laser absorption spectroscopy (TDLAS), two-dimensional (2D) distribution reconstructions of gas temperature are realized using an algebraic reconstruction technique (ART). The results are in agreement with the simulation results, and the time resolution is less than 1 s.

“…The wavelength tuning of the MEMS FP-TF is not only nonlinear, but is also highly dependent on the frequency and the range of the wavelength scan, which makes it difficult to use a look-up table for processing. In previous research with FFP-TFs, we used two athermal-packaged reference gratings (dλ/dT<0.74 pm/°C) that have far-end wavelengths in the FBG array [8, 9]. The wavelength range between the two fixed wavelengths was linear-fitted to minimize the uncertainties caused by random passband variations and quantization errors in the sampling process.…”

The equidistantly spaced multi-passbands of a Fabry-Perot ITU filter are used as an efficient multi-wavelength reference for fiber Bragg grating sensor demodulation. To compensate for the nonlinear wavelength tuning effect in the FBG sensor demodulator, a polynomial fitting algorithm was applied to the temporal peaks of the wavelength-scanned ITU filter. The fitted wavelength values are assigned to the peak locations of the FBG sensor reflections, obtaining constant accuracy, regardless of the wavelength scan range and frequency. A linearity error of about 0.18% against a reference thermocouple thermometer was obtained with the suggested method.

“…A recent technological trend requires temperature sensors to be smaller in size, lighter in weight, and more energy-efficient while operating at a wider temperature range. Meeting these requirements using conventional temperature sensors such as RTD (resistance temperature detector) [28], dielectric ring resonator [29], or optical fiber [30] is challenging due to the complicated fabrication or signal processing requirements. Regarding the temperature sensors based on 2D materials, there exist only very few studies.…”

Transition metal dichalcogenides (TMDs) is an emerging 2D semiconducting material group which has excellent physical properties in the ultimately scaled thickness dimension. Specifically, van der Waals (vdW) heterostructures hold the great promise in further advancing both the fundamental scientific knowledge and practical technological applications of 2D materials. Although 2D materials have been extensively studied for various sensing applications, temperature sensing still remains relatively unexplored. In this work, we experimentally study the temperature-dependent Raman spectroscopy and electrical conductivity of molybdenum disulfide (MoS2) and its heterostructures with platinum dichalcogenides (PtSe2 and PtTe2) to explore their potential to become the next-generation temperature sensor. It is found that the MoS2-PtX2 heterostructure greatly enhances the temperature sensitivity.
