Piezoelectric fatigue fuse wireless sensor for monitoring cyclic loading of civil infrastructure

Brief Description:
A fatigue fuse is designed to break after a set number of loading cycles. This is bonded to a bridge to monitor the loading that leads to metal fatigue and failure. A wireless sensor based on piezoelectric materials monitors the status of the fuse and transmits it to a monitoring station.

Approach:
Develop fatigue fuse technology to obtain accurate load cycle count. Develop piezoelectric pitch-catch system using acoustic waves. Develop cover system for protection from environment. Develop wireless data acquisition and transmission system. Develop energy harvesting system for self-powering.
