Piezoelectric Bending Transducer (D220-H4BR-2513YB) Model:D220-H4BR-2513YB If an electric field is

If an electric field is applied which makes the element thinner

or flexural elements

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

only motion along one axis is utilized

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 If an electric field isA 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.
