This paper summarizes the ongoing work at the University of Texas to develop wireless sensors to monitor the condition of civil engineering structures. The state sensors will be attached to or embedded in the structures during construction and will be interrogated during routine inspections of the structure. Each sensor comprises two components: a switch to detect the damage within the structure and a resonant circuit to transmit the information to the inspector. Prototype sensors have been developed to detect the presence of cracks in welded steel construction and corrosion in reinforced concrete construction.
