Mechanoluminescence for structural health monitoring
Keywords:Mechanoluminescence, Structural health monitoring, Perovskite, Sensors
Mechanoluminescence (ML) is a promising energy-conversion phenomenon for mechanically driven photon sources. Recent research in ML has shown the potential of utilization of the ML materials for fabricating sensors and other devices such as artificial skin, colorful displays, and energy harvesting devices. ML materials can also be used for load sensing in dynamic structures, dynamic pressure mapping, and structural health monitoring by embedding them in composites. Direct conversion of mechanical stimuli (applied load, pressure, impact, etc.) into the light of specific wavelength provides a new direction for designing novel sensing systems. A photo collector device is required to capture the ML light and transforms it into an electrical signal. This article gives an overview of the potential application of ML materials in structural health monitoring.
