“…In last decade, several fiber optic sensors have been realized and reported for temperature sensing. These interferometers include Fiber Brag Grating (FBG) [1][2][3][4], Long-Period Fiber Grating (LPFG) [5][6][7][8], Mode field interferometers [9,10], Mach-Zehnder Interferometers (MZI) [11][12][13][14][15][16], Michelson Interferometers (MI) [17,18], Fabry-Perot Interferometers (FPI) [19][20][21][22][23], Hybrid Interferometers (MZI and FPI) [12,14,24], Interferometer composed of Silicon-on-Insulators (SOI) [25], and Surface Plasma Resonance (SPR) [26]. In these configurations, mostly silica is used as a sensing element for temperature measurement.…”

A highly sensitive temperature sensor based on a polymer cavity of a Fabry-Perot interferometer (FPI) is experimentally demonstrated. The interferometer gives ease in fabrication, and it can be formed by the induction of a thermos-sensitive polymer layer in between two single mode fibers (SMFs). The polymer is used as an FPI cavity for temperature sensing. Due to high thermal expansion coefficient (TEC) and thermos-optic coefficient (TOC) of polymer make the interferometer highly sensitive to ambient temperature. The maximum temperature sensitivity of 2.2209 nm/ • C for the polymer FPI cavity of 40.61 µm in the ambient temperature range of 28 • C to 34 • C is obtained. The proposed sensor shows the advantages of high sensitivity, compactness, simple fabrication, and low cost. Thus, it may become a part of various practical applications in the field of environmental science and engineering sciences.

“…In this process, porous thin films doped with different chemical and biochemical species with sensory abilities, for a given analyte, are easily obtained at room temperature, allowing final structures with mechanical and thermal stability and suitable optical properties [34]. The use of OFS was reported in the measurement of several properties such as pressure [53], temperature [54], strain [55], chemical changes [56], humidity [57], pH [58], and others [59].…”

Sol-Gel Coating Membranes for Optical Fiber Sensors for Concrete Structures Monitoring

et al. 2021

The use of advanced sensing devices for concrete and reinforced concrete structures (RCS) is considered a rational approach for the assessment of repair options and scheduling of inspection and maintenance strategies. The immediate benefits are cost reduction and a reliable prevention of unpredictable events. The use of optical fiber sensors (OFS) for such purposes has increased considerably in the last few years due to their intrinsic advantages. In most of the OFS, the chemical transducer consists of immobilized chemical reagents placed in the sensing region of the optical sensor by direct deposition or by encapsulation in a polymeric matrix. The choice of the support matrix impacts directly on the performance of the OFS. In the last two decades, the development of OFS functionalized with organic–inorganic hybrid (OIH) sol–gel membranes have been reported. Sol–gel route is considered a simple method that offers several advantages when compared to traditional synthesis processes, allowing to obtain versatile materials with unique chemical and physical properties, and is particularly valuable in the design of OIH materials. This review will provide an update of the current state-of-the-art of the OFS based on OIH sol-gel materials for concrete and RCS since 2016 until mid-2021. The main achievements in the synthesis of OIH membranes for deposition on OFS will be discussed. The challenges and future directions in this field will also be considered, as well as the main limitations of OFS for RCS monitoring.

“…Over the years, measurement of surround refractive index (SRI) is increasingly essential in many fields, such as medical biology, environmental monitoring, aerospace, construction industry and meteorological services [1][2][3][4]. Fiber-optic sensors possess good application prospects in SRI measuring, and have drawn a great deal of attention due to several inherently distinctive features, such as low weight, compact size, anti-erosion, chemical and biological inert, immunity to electromagnetic interference and remote operation [5][6][7]. However, due to the thermal-optical effect, the fiber-optic sensor is also sensitive to temperature, and it is difficult to make very precise measurements of SRI.…”
