The structural health monitoring (SHM) system determines the soundness of a building by measuring its shaking caused by an earthquake using sensors installed in the building. The SHM system that we developed jointly with aLab Inc. is beginning to become widely used, and the results of assessing building damage from earthquakes, which can be instantly determined by sensors, are expected to be utilized to ensure the safety of building owners and users, as well as for disaster prevention activities in disaster-stricken areas.
