New material records mechanical stress through luminescence

Identifying crumbling infrastructure is sometimes as difficult as rectifying it. Yet, this process has been made easier thanks to an innovative new material developed by Tohoku University researchers. The new material records stress history through an afterglow and stores it for a long time. By applying the material to the surfaces of structures, researchers can observe changes in the afterglow to determine the amount of stress the material has experienced.
