Structural health monitoring based on aggregation-induced emission active mechanoluminescence organic material

Abstract

The current research aims to design a stress sensor using a recently synthesized organic molecule that exhibits a mechanoluminescence (ML) property. The experimental set-up is established by analyzing different application techniques and modes of capturing real-time emission along with compound and structural material interaction with other molecules. From the implemented experimentations, it was assessed that the emission color and intensity changed when applying axial pressure (direct) and showed the reversible property. This unique attribute contributed by the organic molecule shows the opportunity to develop real-time sensing and non-destructive evaluation methods of structural health monitoring.
