Fiber-optic sensing (FOS) technology has emerged as a cutting-edge research focus in the sensor field due to its miniaturized structure, high sensitivity, and remarkable electromagnetic interference immunity. In 2023, researchers turned submarine cables into earthquake warning systems and gave electric vehicles “optical nerves” to prevent battery failures. However, the current literature contains. Traditional fiber optics have provided valuable insights with record speed for decades, but the demands of modern applications necessitate a leap forward in sensitivity, accuracy, and data analysis capabilities. Renowned for their precision and versatility, they are used in everything from telecommunications to healthcare.
