N2 - This study concerns with the acoustic emissions (AE) monitoring for the applications of rotating machine fault detections. The first prototype wireless AE sensor system with vibrational, thermal and light energy harvesting power supply is presented in this paper. This prototype regularly records the AE signal at 150-250KHz frequency bandwidth and compares with known gear/bearing fault patterns. The data are compressed and transmitted via Zigbee based wireless transceiver to nearby central control unit. The multiple-source energy harvester proposed in this work generates 1.56mW from 0.048g vibration energy and 3.37mW thermoelectric energy when deployed on the 62°C metal surface of a gas compressor. This battery-less wireless AE system achieves power autonomy from environmental energy, realizing a self-powered easy-to-deploy wireless data transmitting based health monitoring solution for wide range of rotating machinery.
