SHM is the advanced way of testing the health of any structure with the help of sensors. Microcontrollers are used to collect the data from the sensors and then the data is evaluated which can be done in real-time which ultimately helps us to know whether the structure is safe or not. Other than these conventional types there are other sensors such as mechanoluminescence (ML) sensors that do not require any external power. ML is a form of luminescence that is produced by mechanical forces such as fracture, friction, stress, crack, tension and compression. This aids us in directly visualizing stress and cracks on the structure’s surface. This review paper aims on discussing some common and widely used ML material along with some of the synthesis and loading techniques. |
