Interrogation of Passive Wireless RF Cavity Sensors

Wireless sensors have attributes such as distributed sensing and wireless connections that make them attractive for civil infrastructure monitoring. A wired physical connection dramatically increases the cost of monitoring systems. For example, the St. Anthony Falls bridge in Minneapolis was reported to cost $3000 per sensor. Wireless sensors are an attractive solution to this problem. Passive wireless sensors are an emerging alternative, where the sensor is a passive device and hence there is no requirement for local power. In this project the intern will explore wireless passive sensors for monitoring rails. The HQP in this proposal will participate in solving challenging problems related to improving the accuracy of the sensor interrogation system.
