Summary
Fiber Bragg Grating (FBG) sensors show promise but face challenges moving from lab to real-world use. The main hurdle for FBG sensing is achieving reliable, scalable operation in practical conditions, not sensor performance.
Area of Science:
- Photonics and Optical Engineering
- Materials Science
- Sensor Technology
Background:
- Fiber Bragg Grating (FBG) sensors offer high sensitivity, multiplexing, and robust performance in harsh environments.
- Despite extensive research, FBG sensor systems show uneven transition from laboratory studies to practical applications.
Purpose of the Study:
- To assess the transition of FBG sensing systems from laboratory validation to practical deployment.
- To analyze publication trends, deployment maturity, application domains, and sensing performance of FBG sensors.
Main Methods:
- Review of publications from 2021-2026 to analyze trends in FBG sensor research and deployment.
- Multi-level assessment combining publication data, deployment maturity, application areas, and performance metrics.
Main Results:
- Most reported FBG systems remain in the laboratory-validation stage; field deployments are limited.
- Structural health monitoring and harsh-environment applications show higher deployment maturity compared to biomedical and chemical sensing.
- Deployment maturity is influenced by sensing mechanism, integration, robustness, complexity, and application demand.
Conclusions:
- The primary challenge for FBG sensing technology is achieving reliable, scalable, and sustainable operation in real-world conditions.
- Sensing performance is no longer the main limitation; focus must shift to practical implementation and operational sustainability.
