A 1-layer piezoelectric actuator produces curvature when one piezo layer expands while the other layer contracts

The bending disks bow in and out like a drum head

Piezoelectric Extending Transducer (T220-A4BR-1305YE) Model:T220-A4BR-1305YE clamp conditionsA 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.
