Abstract
Devices for monitoring structural health conditions of structures. A device includes a bottom substrate layer and an electrical connection layer disposed on the bottom substrate layer. The electrical connection layer includes a middle layer and a pair of generally comb-shaped electrodes disposed beneath the bottom surface of the middle layer. The device also includes one or more piezo-ceramic transducers sandwiched between the bottom substrate layer and the electrical connection layer, wherein the transducers are electrically coupled to the comb-shaped electrodes. The device also includes a top cover layer disposed on the electrical connection layer and means for communicating electrical signals to the piezo-ceramic transducers.
