Piezoelectric Bending Transducer (D220-H4BR-2513YB) Model:D220-H4BR-2513YB the piece expands along the

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

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

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

only motion along one axis is utilized

Piezoelectric Bending Transducer (D220-H4BR-2513YB) Model:D220-H4BR-2513YB the piece expands along theA 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.
