“…Alkhabet et al [ 123 ] developed a fiber optic H 2 sensor using TOF coated with palladium NPs, which can safely and efficiently detect the concentration of H 2 at room temperature. The sensing mechanism is shown in Figure 7 B(a), using a multimode optical fiber as the sensing channel, enhancing the evanescent field in the fiber by tapered treatment (20 μm taper waist), and then coating the TOF with palladium NPs by a drop coating method.…”

Optical fiber sensors based on tapered optical fiber (TOF) structure have attracted a considerable amount of attention from researchers due to the advantages of simple fabrication, high stability, and diverse structures, and have great potential for applications in many fields such as physics, chemistry, and biology. Compared with conventional optical fibers, TOF with their unique structural characteristics significantly improves the sensitivity and response speed of fiber-optic sensors and broadens the application range. This review presents an overview of the latest research status and characteristics of fiber-optic sensors and TOF sensors. Then, the working principle of TOF sensors, fabrication schemes of TOF structures, novel TOF structures in recent years, and the growing emerging application areas are described. Finally, the development trends and challenges of TOF sensors are prospected. The objective of this review is to convey novel perspectives and strategies for the performance optimization and design of TOF sensors based on fiber-optic sensing technologies.

“…2(a). 45 Pd nanoparticles (Pd NPs) were coated on tapered optical fibers, and when exposed to H 2 gas, H 2 molecules migrate toward the Pd-coated surface, where they interact with Pd atoms. The potential energy of these gas molecules reaches a minimum at approximately one molecular radius, causing the adsorption of H 2 gas in the conical region of the fiber.…”

Owing to their advantages of anti-electromagnetic interference, chemical resistance, high sensitivity, and fast response time, optical fiber sensors (OFSs) are widely used in biomedical, environmental monitoring, and food safety fields. We introduce the classification and principles of OFSs and summarize the applications and research progress of OFSs in water quality detection (heavy metals and microorganisms) and air quality monitoring (COx , NOx , and VOCs). Meanwhile, analytical performance, reliability, and environmental adaptability of OFSs are discussed and prospected.
