PROJECT TITLE :
Wireless Passive RFID Crack Width Sensor for Structural Health Monitoring
ABSTRACT:
All mechanical structures are subjected to deformation and cracks, due to fatigue, stress, and/or environmental factors. It is, therefore, of uttermost importance to monitor the mechanical condition of important structures, in order to prevent catastrophic failures, but additionally to attenuate maintenance costs, i.e., avoid unnecessary inspections. A variety of technologies and systems will be used for this purpose: among them, the ones proposing the utilization of wireless passive crackmeters have a sturdy impact potential, in terms of simplicity of installation and measurement and low cost. This paper, hence, shows a crack width wireless radio-frequency identification sensor, developed for applications on various materials (like concrete and metal) and able to detect submillimeter deformations occurring on the object, on which it's placed. A style methodology primarily based on high-sensitivity phase detection is shown.
