Piezoelectric Extending Transducer (Q220-H4BR-1305XE) Model:Q220-H4BR-1305XE The bending disks bow in

The bending disks bow in and out like a drum head

These transducers are often referred to as benders

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

When an electric field having the same polarity and orientation as the original polarization field is placed across the thickness of a single sheet of piezoceramic

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

Piezoelectric Extending Transducer (Q220-H4BR-1305XE) Model:Q220-H4BR-1305XE The bending disks bow inA 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.
