“…It was estimated that the sensor can detect ethanol concentration changes of 1.5% in gasoline–ethanol mixtures and distinguish temperature variations of 0.5 °C. Kumar et al recently utilised a GO-coated Etched FBG (EFBG) sensor for ethanol measurement in petrol [ 85 ]. When compared to an un-coated EFBG, the GO-coated etched FBG (EFBG) demonstrated a ten-fold increase in ethanol sensitivity.…”

A range of optical fibre-based sensors for the measurement of ethanol, primarily in aqueous solution, have been developed and are reviewed here. The sensing approaches can be classified into four groups according to the measurement techniques used, namely absorption (or absorbance), external interferometric, internal fibre grating and plasmonic sensing. The sensors within these groupings can be compared in terms of their characteristic performance indicators, which include sensitivity, resolution and measurement range. Here, particular attention is paid to the potential application areas of these sensors as ethanol production is globally viewed as an important industrial activity. Potential industrial applications are highlighted in the context of the emergence of the internet of things (IoT), which is driving widespread utilization of these sensors in the commercially significant industrial and medical sectors. The review concludes with a summary of the current status and future prospects of optical fibre ethanol sensors for industrial use.

“…Their results displayed as the concentration of Ethanol in water from 0 % to 100 % is better assessed measuring the change in absorbance with the thickest gold layer. Recently, Kumar et al [25] analyzed a graphene oxide-coated FBG for Ethanol detection in petrol. This sensor was manufactured covering a partially chemical etched FBG with a layer of an oxidize graphite powder by means of a drop casting technique.…”

The sensitivity of Fiber Bragg Gratings (FBGs) to the variation of a specific parameter can be improved by choosing a suitable coating material. This paper explores the possibility of measuring the concentration of Ethanol in aqueous solutions by using poly (methyl methacrylate) (PMMA) as coating material of a single-mode FBG. The basic measurement principle relies in the absorption of liquid Ethanol which produces controlled swallowing of the coating, straining the underneath Bragg grating. The PMMA coating was deposited on the FBG by means of a specifically designed dip coating test bench, able to accurately control the thickness of the applied layer. Metrological performances of the developed PMMA-coated FBG Ethanol sensor have been assessed for Ethanol concentrations in the range of 0-38 % in distilled water at 25 °C constant temperature. The prototype shows good repeatability and better sensitivity when compared to an uncoated FBG, especially at low Ethanol concentrations. The dynamic behavior of the sensor (which depends on the kinetics of the absorption mechanism) has been assessed as well, showing a response time of about 290 s, while the recovery time (660 s) was almost twice.

“…Next, the technique used to synthesize the GO solution also have been compared by investigating few works [9][10][11] and it is found that the work by Ridebi et al [11] have performed an easy and simple dip coating technique. The method has been conducted by dipping the fiber in the 200 µL GO aqueous solution at a constant speed.…”

The rapid development and deployment of optical sensors have brought fibre Bragg grating (FBG) as a renowned optical sensor which acquired high sensitivity, fast response to the measurement changes and small in size. However, the implementation of bare FBG sensor could be further enhanced to give significant impact in terms of sensitivity without any alteration on the effective refractive index and the grating period. Therefore, a low cost and high temperature sensitivity of fiber Bragg grating (FBG) sensor coated with graphene oxide (GO) is designed and constructed. The FBG is synthesized with GO by implementing dip coating technique. Then, the bare and coated FBG sensor is tested by applying heat at the grating region of the FBG. The output of the experiment is displayed on the optical spectrum analyzer (OSA) in terms of power (dBm) and wavelength (nm). The performances of the FBG sensors have been evaluated by comparing the temperature sensitivity. The GO-coated FBG recorded better temperature sensitivity of 16.0 pm/°C compared to the bare FBG with sensitivity of 15.0 pm/°C. The results indicate the ability of graphene oxide to improve the Bragg wavelength shift by the combined effect of effective refractive index and grating period that are influenced by the changes of temperature. GO-coated FBG also exhibits better linear fit of 99.1%, which specifies the consistency of the wavelength shift reading as temperature increased and low limit of detection (LOD) compared to the bare FBG as the minimum value of LOD signifies the effectiveness of the sensor.
