Piezoelectric Bending Transducer (D220-H4BR-2513YB) Model:D220-H4BR-2513YB or flexural elements

or flexural elements

If an electric field is applied which makes the element thinner

Motion in the radial direction is typically on the order of microns or tens of microns

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

Piezoelectric Bending Transducer (D220-H4BR-2513YB) Model:D220-H4BR-2513YB or flexural elementsA 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.
