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
