Abstract:Problem: Structural health monitoring is critical to protecting bridges against aging,
failures, and potentially collapse. However, instrumentiation techniques
suffer from non-scalability due to the high cost of instrumentation devices
and installation, and potentially high maintenance costs. While manual
inspections of bridges help, they may not provide enough information to
prevent catastophic failures.
Objective: The objective of this project was to develop and test a cost effective and
scalable solution for the real time monitoring of bridges for strain, tilt and
inclination, temperature, moisture and humity, pressure, and crack
activity and growth. The solution developed and studied as a part of this
project, is based on Active RF Test (ART) technology which incorporates
novel sensing, energy harvesting, and wireless communication
technologies into a wireless and batteryless sensor.
