Abstract

Optical fiber flexible wearable sensors are extensively utilized in healthcare, sports training, smart textiles, and environmental monitoring, owing to their lightweight, portability, biocompatibility, and excellent stretchability. These sensors are distinguished by their high sensitivity, accuracy, and non-invasive monitoring capabilities, excelling at detecting subtle mechanical changes like respiratory rate and muscle activity. Additionally, they offer significant advantages regarding biocompatibility and resistance to electromagnetic interference. Recent research has concentrated on enhancing the performance and flexibility of optical fiber sensors by incorporating novel materials such as polydimethylsiloxane, polymethyl methacrylate, and hydrogels, which improve their stretchability and optical transparency. Furthermore, integrating machine learning and Internet of Things (IoT) technologies has enabled optimized data processing, facilitating real-time, precise monitoring of physiological parameters. However, challenges related to sensor integration, stability, and cost persist. Addressing these issues is crucial for establishing optical fiber wearable sensors as reliable clinical tools. This paper reviews the latest advancements in optical fiber flexible wearable sensors, discussing their working principles, manufacturing processes, and applications in healthcare, sports, and smart textiles. It also highlights challenges related to sensor design, energy management, data transmission, and integration with artificial intelligence, offering recommendations to improve sensor performance and broaden their application scope.

期刊介绍： Talanta provides a forum for the publication of original research papers, short communications, and critical reviews in all branches of pure and applied analytical chemistry. Papers are evaluated based on established guidelines, including the fundamental nature of the study, scientific novelty, substantial improvement or advantage over existing technology or methods, and demonstrated analytical applicability. Original research papers on fundamental studies, and on novel sensor and instrumentation developments, are encouraged. Novel or improved applications in areas such as clinical and biological chemistry, environmental analysis, geochemistry, materials science and engineering, and analytical platforms for omics development are welcome. Analytical performance of methods should be determined, including interference and matrix effects, and methods should be validated by comparison with a standard method, or analysis of a certified reference material. Simple spiking recoveries may not be sufficient. The developed method should especially comprise information on selectivity, sensitivity, detection limits, accuracy, and reliability. However, applying official validation or robustness studies to a routine method or technique does not necessarily constitute novelty. Proper statistical treatment of the data should be provided. Relevant literature should be cited, including related publications by the authors, and authors should discuss how their proposed methodology compares with previously reported methods.
