Micromachining of High-Quality PMN-PT/Epoxy 1-3 Composite for High-Frequency (>30 MHz) Ultrasonic Transducer Applications.

Fabricating PMN-PT composites, the core component of high-frequency (> 30 MHz) transducers, remains challenging due to their poor machinability and ultrasmall kerfs. This urgent problem is significantly impeding the development of PMN-PT ultrasonic transducers for use in clinical research, biomedical sciences, and nondestructive testing (NDT). In this study, high-quality PMN-0.
