Piezoelectric Bending Transducer (Q220-A4BR-1305YB) Model:Q220-A4BR-1305YB 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

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

PSI-5H4E is an industry type 5H (Navy Type VI) piezoceramic

Piezoelectric Bending Transducer (Q220-A4BR-1305YB) Model:Q220-A4BR-1305YB and bender force from tensA 2 layer piezoelectric actuator produces curvature when one piezo layer expands while the other layer contracts. These transducers are often referred to as benders, bimorphs, or flexural elements. Bender motion on the order of hundreds to thousands of microns, and bender force from tens to hundreds of grams, is typical. The brass shim reinforcement laminated between the two piezoelectric layers is an economical approach to producing a rugged actuator.
