PiezoNova offers high-quality piezo elements from PZT (Lead Zirconate Titanate).
The PZT has been divided into a two predominant types witch both provide a unique properties suitable for applications.
The types are „Hard material“ for high power and „Soft material“ for high sensitivity.
PiezoNova offers PZT elements of various types and sizes manufactured to fit the specific needs of the customer.
All dimensions, shape (disc, plate, ring, tube, shear paltes, or hemisphere), are manufactured to custom-made.
The electrodes are standardly silver or gold.
Wrap-around electrode (WAE) and the elements with soldered wires are also available.
Are you looking for a piezo element for the current application?
We understand that changing suppliers is often complicated.
We will advise you on which material will be best chosen so that your product retains its key properties.
Are you looking for a piezo element for a new application?
We are able to design a piezo element directly for your application and provide you piezoelectric technical support.
PiezoNova offers elements from prototypes to mass production.
