Mota Soares, T1 - Distributed strain measurement using polymer optical fiber integrated in technical textile to detect displacement of soil T2 - Smart structures and materials : III ECCOMAS thematic conference N2 - Sensing characteristics of polymer optical fibers (POF) are studied using the optical time-domain reflectometry technique. For the first time to our knowledge, investigations are carried out with respect to integration of POF in technical textiles for distributed measurement of mechanical deformation. The research on this new sensor type focuses on its application in monitoring of geotechnical structures such as railway embankments, dikes, slopes and dams. We report on a distributed sensor system using POF integrated in technical textiles as sensing elements for measurement of displacement of soil. This sensor system is very robust – it withstands the integration under rough condition at a construction site – and can detect strain of more than 40 % over distances of more than 100 meters.
