  • Piezoceramic-based smart aggregate for unified performance monitoring of concrete structures
    Patent number: 7987728
    Abstract: A system for monitoring the health of a structure, e.g., a concrete wall, bridge, pillars, using a smart aggregate is disclosed. The smart aggregate includes a piezoceramic transducer(s) and associated communication links. The transducer is embedded into the structure prior to the manufacture of the structure. The disclosed system can monitor internal stresses, cracks and other physical forces in the structures during the structures' life. The system is capable of providing an early indication of the health of the structure before a failure of the structure can occur.
