Sensors based on fiber optics have seen widespread use in structural monitoring in recent years. Because of their modest size, they may be extensively employed in structural parts of many kinds. New sensing technologies for civil constructions’ health have been developed in recent years thanks to developments in optical fiber fabrication. An outline of our study into the creation of structural fiber optic sensors is given here. Fiber optic sensors can accurately monitor strain, stress, and temperature in a variety of constructions, as shown by this study. Several instances of structural components’ strain, stress, and temperature have been shown in this study. Civil engineers now have a good option for monitoring civil infrastructure performance because to recent advancements in fiber optic sensor technology. Due to their compact size, high resolution, and long-distance signal transmission capabilities, fiber optic sensors are a suitable choice for a variety of applications. As an added benefit, they’re impervious to electromagnetic and radio frequency interference, and they can accommodate numerous probed sensors concatenated onto a single fiber. Fiber optic sensors provide a number of benefits over conventional damage detecting techniques and equipment, at least in certain instances.
