Abstract
Methods, apparatuses, and systems for damage detection and for other detection of the state of a structure or material. Such damage detection and detection of the state of a structure may be performed and operated without the use of baseline data. The present invention may operate using time reversal acoustics or polarization characteristics of piezoelectric devices. The present invention may include a piezoelectric device including two or more piezoelectric transducers.
