Piezoelectric Bending Transducer (Q220-H4BR-1305YB) Meta||Mass (grams)||20.8 The brass shim reinforcement laminated

The brass shim reinforcement laminated between the two piezoelectric layers is an economical approach to producing a rugged actuator

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

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

Because they have no center shim reinforcement

The bending disks bow in and out like a drum head

Piezoelectric Bending Transducer (Q220-H4BR-1305YB) Meta||Mass (grams)||20.8 The brass shim reinforcement laminatedA 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.
