Self-Diagnosing Transducers and Systems and Methods Therefor

A transducer system that includes a piezoelectric transducer and a self-diagnosis system electrically connected to the transducer. In one embodiment, the self-diagnosis system is configured to detect when a debonding defect has occurred in the bond between the transducer and a host structure and to detect when a crack has occurred in the transducer itself. The self-diagnosis system implements debonding-detection and crack-detection schemes that can distinguish between debonding and cracking, as well as distinguish these problems from changes arising from temperature variation.
