Piezoelectric Bending Transducer (T220-H4BR-1305XB) Meta||Price||$546 This material provides a compromise

This material provides a compromise between PZT 5A and 5H

It also exhibits good performance as a resonant actuator

The motion in the thickness direction is on the order of tens of nanometers

A 2-layer piezoelectric actuator produces curvature when one piezo layer expands while the other layer contracts

or flexural elements

Piezoelectric Bending Transducer (T220-H4BR-1305XB) Meta||Price||$546 This material provides a compromiseA 2 layer piezoelectric actuator produces curvature when one piezo layer expands while the other layer contracts. These transducers are often referred to as benders, bimorphs, or flexural elements. Bender motion on the order of hundreds to thousands of microns, and bender force from tens to hundreds of grams, is typical. The brass shim reinforcement laminated between the two piezoelectric layers is an economical approach to producing a rugged actuator.
