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

and bender force from tens to hundreds of grams

It operates over a wide temperature range and is relatively temperature insensitive

These transducers are often referred to as benders

It has high motion per volt sensitivity but its upper temperature range is limited and its properties are more sensitive to temperature

PSI-5A4E is an industry type 5A (Navy Type II) piezoceramic

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.
