Keywords:
Fiber Bragg Grating, Single Mode Fiber, Structural Health Monitoring, Sensor Strain, Internet of ThingsAbstract
This study aims to analyze the development of Fiber Bragg Grating (FBG) design in Single Mode Fiber (SMF) as a strain sensor for building structure monitoring based on the Internet of Things (IoT) through a meta-analysis of 26 scientific articles published in the last five years. The study was conducted by examining key parameters such as grating configuration, strain sensitivity, temperature compensation techniques, packaging methods, optical interrogator integration, and sensor application in various types of structures. The analysis results show that FBG-SMF technology has advantages such as high sensitivity, linear response, resistance to electromagnetic interference, and long-distance transmission capabilities, making it an important component in the development of modern Structural Health Monitoring (SHM) systems. Integration with IoT has been proven to increase monitoring effectiveness through real-time data acquisition and opportunities for predictive analytics applications. However, a number of challenges, such as thermal instability, the lack of installation standards for large-scale structures, and interrogator performance variations, still require further research. Overall, this meta-analysis confirms that IoT-based FBG-SMF is a promising sensing solution, but it still requires refinement in terms of sensor design, system integration, and implementation standardization to support more reliable and sustainable structure monitoring.
