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

or flexural elements

only motion along one axis is utilized

When an electric field having the same polarity and orientation as the original polarization field is placed across the thickness of a single layer disk

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

A 1-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.
