These developments, although from different areas, have collectively paved way for concrete structures with non-corrosive reinforcement and in-built sensors. Therefore, the purpose of this effort is to bridge the gap between civil engineering and sensor engineering communities through an overview on the up-to-date technological advances in both sectors, with a special focus on textile reinforced concrete embedded with fiber optic sensors. The introduction section highlights the importance of reducing the carbon footprint resulting from the building industry and how this could be effectively achieved by the use of state-of-the-art reinforcement techniques. Added to these benefits would be the implementations on infrastructure monitoring for the safe operation of structures through their entire lifespan by utilizing sensors, specifically, fiber optic sensors. The paper presents an extensive description on fiber optic sensor engineering that enables the incorporation of sensors into the reinforcement mechanism of a structure at its manufacturing stage, enabling effective monitoring and a wider range of capabilities when compared to conventional means of structural health monitoring. In future, these developments, when combined with artificial intelligence concepts, will lead to distributed sensor networks for smart monitoring applications, particularly enabling such distributed networks to be implemented\/embedded at their manufacturing stage.<\/jats:p>","DOI":"10.3390\/s21154948","type":"journal-article","created":{"date-parts":[[2021,7,22]],"date-time":"2021-07-22T22:35:31Z","timestamp":1626993331000},"page":"4948","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":66,"title":["Fiber Optic Sensors Embedded in Textile-Reinforced Concrete for Smart Structural Health Monitoring: A Review"],"prefix":"10.3390","volume":"21","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8488-2992","authenticated-orcid":false,"given":"Lourdes","family":"Alwis","sequence":"first","affiliation":[{"name":"School of Engineering and the Built Environment, Edinburgh Napier University, 10 Colinton Road, Edinburgh EH10 5DT, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kort","family":"Bremer","sequence":"additional","affiliation":[{"name":"Hannover Centre for Optical Technologies, Leibniz University of Hannover, 30167 Hannover, Germany"},{"name":"Cluster of Excellence PhoenixD (Photonics, Optics, and Engineering\u2014Innovation Across Disciplines), 30167 Hannover, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9389-7125","authenticated-orcid":false,"given":"Bernhard","family":"Roth","sequence":"additional","affiliation":[{"name":"Hannover Centre for Optical Technologies, Leibniz University of Hannover, 30167 Hannover, Germany"},{"name":"Cluster of Excellence PhoenixD (Photonics, Optics, and Engineering\u2014Innovation Across Disciplines), 30167 Hannover, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2021,7,21]]},"reference":[{"key":"ref_1","unstructured":"(2021, July 18).
