The research team led by computer scientist Gul Agha and civil engineer Bill Spencer has created an inexpensive system for continuous, reliable structural health monitoring. The approach uses dense arrays of wireless smart sensors and concurrent and distributed real-time processing to overcome the limitations inherent in traditional systems. The team has produced a customizable software framework that simplifies development for smart sensor platforms. In 2009, the team deployed the largest civil infrastructure monitoring system to date, and the only one using dense wireless arrays, on Jindo Bridge in South Korea. The ISM400/Imote2 platform provides a commercial device with the ability to collect synchronized, high-fidelity, and vibration data wirelessly. The device addresses the needs of the rapidly growing dynamic sensing community, particularly with respect to the performance and health of structures. Large-scale, practical structural health monitoring deployments using smart wireless sensors will soon be commonplace.
