Abstract :-Structural Health Monitoring (SHM) is a diagnostic approach used to assess modern structures, which involve monitoring a structure to detect changes in its structural state. Smart materials play a crucial role in the development of functionality. These materials can sense the surroundings and detect the changes thereof and respond to external stimuli. The application of smart materials allows a better understanding of the structure's conditions, leads to cost-effective infrastructure management, and improves structure lifespan and public safety. This paper presents an innovative smart material using Mechanoluminescence (ML) material as a smart sensor to detect damage in structures that emits light when subjected to external mechanical action. ML materials have great potential in applications to stress sensing techniques, damage sensors, and safety management monitoring systems. The characteristics and potential applications of ML in the field of structural health monitoring are discussed. The research achievements of various well known mechanoluminescent materials for a better understanding of ML phenomena are also reviewed. At present, the development of ML material has been initiated by many researchers as a diagnostic method, and it has to be applied to real social infrastructure.
