Piezoelectric Extending Transducer (Q220-A4BR-1305XE) Model:Q220-A4BR-1305XE A 2-layer piezoelectric actuator produces

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

The motion in the thickness direction is on the order of tens of nanometers

This allows the user to experiment with using the device in series or in parallel and also in bending mode or in extension

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

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

Piezoelectric Extending Transducer (Q220-A4BR-1305XE) Model:Q220-A4BR-1305XE A 2-layer piezoelectric actuator producesA 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.
