Piezoelectric Bending Transducer (T220-H4BR-1305XB) Meta||Price||$546 Due to its smaller size

Due to its smaller size and good performance this is a popular product for many applications

the piece expands along the axis of polarization (thickness direction) and contracts perpendicular to the axis of polarization (length and width direction)

It is not recommended for applications requiring high force output

extension along the length and width results

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

Piezoelectric Bending Transducer (T220-H4BR-1305XB) Meta||Price||$546 Due to its smaller sizeA 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.
