In the MHz range, ultrasonic transducers are widely used in medical imaging, probes, underwater inspection, and related applications.

Reduced matching difficulty in the MHz band.

The acoustic impedance of piezoelectric ceramics is significantly lowered, enabling better matching with low-impedance media such as water, tissue, and polymers. This reduces reflection and improves acoustic energy transmission efficiency, making high-frequency applications that were previously difficult to couple technically feasible.

In the MHz band, piezoelectric plates are prone to lateral-mode interference, which can lead to spectral impurity or blurred signals. Composite structures can absorb part of the lateral-mode energy, acting as a natural mechanical filter that helps improve main-mode purity and frequency response.

Low-acoustic-impedance piezoelectric ceramics, when used in composite configurations, can enhance overall mechanical strength and improve manufacturability while maintaining high-frequency response and good beam control. For example, in high-frequency medical ultrasound probes (20–40 MHz), such structures have been proven to outperform conventional monolithic ceramics.

Flexible electrical performance.
Key properties such as piezoelectric constants and acoustic impedance can be tuned.
Qm can be reduced to below 15, while dh reaches 140 at 20 MPa.
Geometry and polarization direction can be customized to customer designs.
High axial resolution is enabled by the low mechanical Q factor, delivering broadband performance and short-pulse output.
