High-Performance Materials for Piezo Applications
Hard Piezoelectric Ceramic Element
These materials withstand both high electrical driving voltages and intense mechanical (pressure) loads and are characterized by:
- Low dielectric loss
- Permittivity in between 900 and 1400
- High mechanical quality factor in between 500 and 2000
- High Curie temperature
- High coercive field strength
Materials of this type are specifically well suited for high-performance ultrasonic applications in the range from 20 kHz to several MHz.
Soft Piezoelectric Ceramic Element
- Permittivity in between 1000 and 2000
- High piezoelectric activity (d33 ≥ 400 * 10-12 C/N)
- Low mechanical quality factor (≤100)
Sensor applications are mainly combined systems in which the piezoceramic is used as ultrasonic transmitter on the one hand and as a receiver on the other hand. SONOBIO P53, P54 are specially developed materials with a high rate of thermal and temporal stability. For this reason, they are very suitable for automotive applications and others in the area ranging from –40 to +160º Celsius.
Single Crystal PIN-PMN-PT PiezoCeramic
We specialize in the development and manufacture of advanced lead magnesium niobate–lead titanate (PMN-PT) and lead indium niobate–lead magnesium niobate–lead titanate (PIN-PMN-PT) single crystal materials, delivering some of the highest piezoelectric performance available in the industry.
