Zusammenfassung:	Described are various embodiments of an ultrasonic structural health monitoring device, system and method. In one embodiment, an ultrasonic structural health monitoring device is described to monitor a structure. The device comprises a bottom electrode disposable on the structure; a piezoelectric medium disposed on the bottom electrode; a top electrode disposed on the piezoelectric medium; an acoustic insulation layer; and a connector to bring electrical excitation for the piezoelectric medium and to collect a generated electric response therefrom representative of structural health.
