Abstract:Bridges and other highway structures age, crack, and weaken over time. They can deteriorate because of wear and tear from everyday traffic, weather events, and crashes. The Federal Highway Administration (FHWA) requires a visual inspection of bridges every two years.1 Inspections may not always provide a complete picture of structural conditions because the naked eye cannot detect internal changes or damage that occurs at a microscopic level. FHWA’s Exploratory Advanced Research (EAR) Program is supporting the following research to develop self-powered wireless sensors that can monitor structural health or assess bridge conditions. Michigan State University (MSU) is working on a project focused on structural health monitoring using wireless monitors. The project is called the “Ultra Low-Power Wireless Sensing System.” Washington University in St. Louis and the University of Southern California are collaborating with MSU on this project. Drexel University researchers are developing a suite of portable wireless sensors to provide important baseline data on structural health. These sensors can be installed as needed to assess damage from floods, accidents, or similar incidents that might compromise structural integrity. The Drexel research, “Multipurpose Wireless Sensors for Asset Management and Health Monitoring of Structures,” is being carried out in partnership with Smartsensys.
