Functionalized Optical Fiber Sensors with Smart Material Integration

This book explores the integration of smart materials with optical fiber technology to develop advanced sensing systems for real-time, high-precision applications. Functionalized optical fiber sensors (FOFS) leverage tailored coatings, nanostructures, and responsive materials to investigate a wide range of physical, chemical, and biological parameters with remarkable sensitivity and reliability. The book provides a comprehensive overview of the design principles, functionalization techniques, and fabrication methods that underpin FOFS technology. It focuses into emerging materials—including nanomaterials, graphene, and polymers—that enhance the performance and selectivity of these sensors. Key applications discussed include refractive index sensing, ph sensing, temperature sensing, structural health monitoring, biomedical diagnostics, environmental surveillance, industrial automation, and energy systems. Emphasis is placed on the multidisciplinary nature of FOFS, highlighting how advances in photonics, material science, and data analytics converge to support intelligent sensing solutions. The book also addresses challenges in scalability, durability, and integration with wireless and AI-based platforms. It serves as both a foundational reference and a guide to emerging trends in functionalized fiber optic sensing. It is particularly relevant in the context of Industry 5.0, where adaptive, networked, and sustainable technologies are at the forefront of innovation.
