“…Reducing the amount of ethanol produced a red shift in the observed spectrum due to the higher RI of pure G87 Gasoline. Marfu’Ah et al proposed an alternative configuration of MMI based on splicing a short length of singlemode fibre between two multimode fibres as a multimode–singlemode–multimode (MSM) structure where part of the energy of the core mode is transferred to cladding modes [ 74 ]. Experiments were performed using the MSM sensor with and without a novolac resin coating.…”

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.

“…Additional attractive features of POFs i.e., ruggedness, flexibility, ease of fabrication, low cost, and ability to be operated in the visible range, have sparked considerable interest among researchers, making them an attractive choice for developing optical fibre ethanol sensors for industrial applications. The ethanol concentration measurement has been proposed using a variety of POF sensors , for example, polyvinyl alcohol (PVA) and SiO2 coated tapered sensor 4 , an unclad sensor coated with carbon nanotube (CNT) and graphene oxide (GO) 5 , an uncoated U-bend sensor 6 , a U-bent sensor based on localized surface plasmon resonance (LSPR) 7 and a D-shaped sensor based on surface plasmon resonance 8 Heterocore structured designs for refractive index sensing using GOFs have also attracted significant attention [9][10][11] however, the use of POFs for heterocore structured sensors remains a novel and unique concept. In this work, a side-polished balloon shape heterocore structured POF ethanol sensor using fibres of two different core diameters is investigated.…”

A unique side-polished balloon shaped heterocore structure plastic optical fibre (POF) sensor for real-time measurement of very low to high ethanol concentration in water is reported. The sensor is designed as a large core-small core-large core heterocore structure where small core fibre (SCF) acts as a sensing region, whereas large core fibre (LCFs) are used as input and output light waveguide s as well as to introduce the light leakage in the cladding of SCF at the heterocore structure’s input interface and hence generate the significant evanescent field. The principle of operation of the sensor is based on evanescent field interaction at the interface of modif ied SCF and the liquid boundary. The sensor is characterized for ethanol-water solutions in the ethanol concentration ranges of 20 %v/v to 80 %v/v, 1 %v/v to 10 %v/v, and 0.1 %v/v to 1 %v/v, demonstrating a maximum sensitivity of 54673 %/RIU. The experimentally evaluated high sensitivity of this sensor design for real-time measurement of ethanol concentration in water at different ranges makes it a potential candidate for implementation in the industry as a low-cost and real-time solution for ethanol sensing as well as other RI sensing applications.
