The sensor comprises of a length of fiber optics which is designed into a geometrical shape to give a sensing effect of structural displacement and it can be installed on the surface or embedded into the structure. The magnitude of the fault and its location can be precisely detected to within 1 meter of the detection length. This sensor is not only lightweight and compact; it is cost-effective and the fault can be monitored remotely from multiple locations along the line of detection. Additional sensor heads in the system would not contribute to additional cost to the existing system. This sensing system is capable of making an early prediction of major fault in the structure and would contribute significantly to the public safety and property. This sensing system can be made to be monitored at real-time 24/7 remotely in computers and could provide alarm through wireless system such as to mobile phones.
