This review provides a comprehensive overview of FBG sensor technology, focusing on their operating principles, key advantages such as high sensitivity and immunity to electromagnetic interference, and common challenges like temperature-strain cross-sensitivity and the high. Fiber Bragg grating (FBG) sensors have emerged as advanced tools for monitoring a wide range of physical parameters in various fields, including structural health, aerospace, biochemical, and environmental applications. This review provides a comprehensive overview of FBG sensor technology. Fiber Bragg grating sensors (FBGs) have gained rapid acceptance in aerospace and automotive structural health monitoring applications for the measurement of strain, stress, vibration, acoustics, acceleration, pressure, temperature, moisture, and corrosion distributed at multiple locations within. A fiber Bragg grating (FBG) is an optical device that reflects light within a specific wavelength while allowing others to pass through; this is owing to the periodic variations in the refractive index of the fiber core. Strain sensors based on FBGs are becoming an essential part of smart factory. Fiber Bragg grating strain sensors employ fiber optic principles for strain detection. These sensors possess great sensitivity and reliability, which explains their growing popularity across various engineering and monitoring applications.
