Shapes, poling modes, markets and documents for X6B.

Shapes: Disc
Rod
Plate
Bar
Rings
Tolerances and metallization
Poling: ThicknessThe part is poled through the thickness and electroded on the positive and negative surfaces. Available for all part shapes.
ShearThe polarization direction is perpendicular to the electroded surfaces. Commonly supplied as plates and rings; offers increased sensitivity and minimises the pyroelectric effect.
RadialOffered on tubes and rings, including tubes with a wrap-around electrode.
Used in: Medical ultrasound
Sonar, where a shorter device delivers the same output
Adaptive optics
Energy harvesting
Actuation at ambient and cryogenic temperatures
Generation: Gen III
Operating limits: Temperature, stress and field limits in the purchase terms
