More info
PZT Ring is a disc-shaped piezoelectric ceramic with a central hole, engineered for efficient energy conversion in radial or axial vibration modes. Due to its geometry and material properties, it is ideal for applications requiring uniform acoustic distribution, such as ultrasonic transducers, pressure sensors, and piezoelectric actuators. The ring structure enhances mechanical coupling while minimizing stress concentration, making it suitable for high-performance and long-life operation. Heeger Materials offers PZT Rings in various sizes and polarizations to meet the specific requirements of medical, industrial, and research-grade piezoelectric systems.
PZT Ring Selection Notes
PZT Ring belongs to the PZT piezoelectric ceramic range and is selected for controlled PZT composition, piezoelectric response, dielectric properties, geometry, electrode pattern and polarization direction.
