Corrosion of rebar in concrete bridges is a problem for the infrastructure and is difficult to detect. Engineers and scientists at the Johns Hopkins University Applied Physics Laboratory (JHU/APL) have developed a device that is designed to be buried in the concrete when the bridge deck is poured. The device, known as a wireless embeddable sensor platform/smart aggregate (WESP/SA), can provide data about conditions within the bridge deck. This data will assist highway maintenance engineers in determining corrosive actions.
