Abstract

Apparatus for monitoring structural health conditions of structures. The apparatus includes a piezoelectric device that has a bottom cover plate, piezoelectric rings concentrically disposed with respect to an axis and positioned on the bottom cover plate, and concentric filler rings made from an electrically insulating material. Each of the piezoelectric rings is interposed between two adjacent filler rings. The piezoelectric device also includes electrical connection means for communicating electrical signals to the piezoelectric rings and a top cover plate that is positioned over the piezoelectric rings and filler rings. The electrical connection means are operative to transmit electrical signals that cause one or more of the piezoelectric rings to generate waves or transmit electrical signals developed by one or more of the piezoelectric rings in response to the waves.
