ECE researchers are designing power conditioning circuits for a system, in which a piezoelectric patch harvests energy from vibrations in a bridge. Dong Ha’s team is collaborating with Dan Inman, Director of Virginia Tech’s Center for Intelligent Material Systems and Structures (CIMSS) on a project to develop a suite of new technologies to provide continuous, energy-independent monitoring of the structural integrity of bridges. CIMSS is partnering with Physical Acoustics Corp. of Princeton Junction, N.J. on the $14 million project funded by the National Institute of Standards and Technology (NIST).
