Abstract :
This work demonstrates a condition-based solution for monitoring the long-term health of a system with moving or rotating parts. This is accomplished through the direct measurement of loads appearing on the structure by means of a synchronized network of wireless sensors. The wireless sensors exhibit extremely low power requirements, allowing high sampling rates while sustaining battery life entirely through means of energy harvesting. In addition, the network utilizes methods of TDMA to organize transmission scheduling and perform real-time error correction.
