Subsurface damage identification and localization in PZT ceramics using point contact excitation and detection: An image processing framework.

Piezoelectric sensors hold immense potential in structural health monitoring (SHM) applications. However, their performance can be deteriorated by defects and extreme weathering. Therefore, diagnosing the sensor before implementation is very crucial.

Stiffness tensor estimation of anisotropic crystal using point contact method and unscented Kalman filter.

The potential application of Lithium Niobate (LiNbO) crystal is immense, specifically in the domain of meta-surfaces and nano-resonators. However, the practical application of LiNbO is impeded due to unreliable experimental techniques and inaccurate inversion algorithms for material characterization. In the current research, material characterization of anisotropic crystal is proposed by exploring the wavefield evolution in the spatial and temporal domains.
