Piezoelectric Bending Transducer (Q220-H4BR-1305YB) Meta||Mass (grams)||20.8 PSI-5H4E is an industry type

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

Bender motion on the order of hundreds to thousands of microns

This allows the user to experiment with using the device in series or in parallel and also in bending mode or in extension

The bending disks bow in and out like a drum head

Piezoelectric Bending Transducer (Q220-H4BR-1305YB) Meta||Mass (grams)||20.8 PSI-5H4E is an industry typeA 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.
