First bridge in Germany with embedded strain and crack distributed sensors
EpsilonRebars and EpsilonSensors were integrated (embedded) inside the steel-concrete bridge, which is the first such type of smart bridge in Germany. The DFOS-based monitoring system was designed to provide the possibility of analysing strains in concrete, in steel reinforcing bars, as well as to detect all the microcracks and calculate vertical displacements (deflections). Also, additional distributed temperature measurements were applied for appropriate thermal compensation.

Benefits of using the DFOS monitoring system
Results of using the DFOS monitoring system
EpsilonRebars (ER) and EpsilonSensors (ES) were secured by tightening them to the existing reinforcement. These sensors are dedicated to analysing strains and cracks directly inside the concrete (both within the lower and upper part of the slab). Moreover, a modified version of ES without an outer braid was successfully glued directly to the selected reinforcing bar to monitor its strains.
