High sensitive Soft PZT materials are particularly useful for sensing applications due to its high sensitivity and permittivity. As such these piezoelectric ceramics are frequently used in low power applications as transducers, receivers and generators.
PZT is a machineable ceramic and can be precision dimensioned into tubes, rings, discs, plates, and hemispheres. The PZT material is also versatile from a forming aspect as it can be net shaped by pressing, extruding and casting into these same shapes as well as complex components including, co-fired bimorphs and multilayer actuators. Sizes range from microns to centimetres. Electrode choices are extensive including fired silver, electroless nickel, sputtered or vacuum deposited Nickel-Chrome, Gold, Tin, Aluminium and Vanadium.
