Bender motion on the order of hundreds to thousands of microns

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

Piezoelectric Extending Transducer (T220-A4BR-1305YE) Model:T220-A4BR-1305YE they are not intended toA 2 layer element behaves like a single layer when both layers expand (or contract) together. If an electric field is applied which makes the element thinner, extension along the length and width results. Typically, only motion along one axis is utilized. Extender motion on the order of microns to tens of microns, and force from tens to hundreds of Newtons is typical.
