Fiber optic sensors (FOS) are made of high-purity silica, which are immune to chemical attacks and electromagnetic interference. The purpose of this review is to summarize FOS development and its application in. Abstract This literature review examines the application of Fibre Optic Sensors (FOS) in the structural health monitoring of concrete buildings, an increasing issue in contemporary construction owing to the demand for safer and more resilient infrastructure. The concept and functions of smart concrete have thus been partially realized.
