The Development of Fiber Optic Sensors in the Next Decade
Fiber optic sensors are on the cusp of a transformative era. By 2025, advancements in materials, integration with AI and IoT, and improved portability will unlock a world of possibilities. But as we approach 2025, exciting advancements are on the horizon that could redefine how these sensors work. Optical fiber sensors (OFSs) have emerged as essential tools in the monitoring of physical, chemical, and bio-medical parameters in harsh situations due to their high sensitivity, electromagnetic interference (EMI) immunity, and long-term stability. In 2023, researchers turned submarine cables into earthquake warning systems and gave electric vehicles “optical nerves” to prevent battery failures. Distributing sensing combined to scattering level spatial multiplexing techniques permits a large amount of sensing points in small area or volume, often mandatory in biomedical field. The fiber becomes the sensor while the interrogator injects laser energy into the fiber and detects.
