Piezoelectric Extending Transducer (Q220-H4BR-1305XE) Model:Q220-H4BR-1305XE and bender force from tens

and bender force from tens to hundreds of grams

The bending disks bow in and out like a drum head

or flexural elements

If an electric field is applied which makes the element thinner

only motion along one axis is utilized

Piezoelectric Extending Transducer (Q220-H4BR-1305XE) Model:Q220-H4BR-1305XE and bender force from tensA 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.
