Spring 2022
For large-scale metallic structures, such as aircraft, ships, and pipelines, their failure could be catastrophic. A structural health monitoring system (SHM) to detect failures in advance is essential. The Internet-of-Things (IoT) is a key technology applied for remote structural health monitoring
research is to design and develop an IoT-based structural health monitoring system that includes an ultra-low-power miniaturized sensing node integrated with a three-dimensional (3D) stress and strain sensor. The system can monitor 3D stress and strain values and upload them to the cloud. The developed IoT
-in BLE wireless communication function, a high precision 16-bit analog-to-digital converter (ADC) and a 32Mbytes flash memory. It interfaced with a compact 3D MEMS strain-gauge typed sensor (7mm x 7mm) developed by a team in mechanical engineering at the University of Alberta. The sensor has high
