The bending disks bow in and out like a drum head
This allows the user to experiment with using the device in series or in parallel and also in bending mode or in extension
Motion in the length direction is typically on the order of microns or tens of microns
The brass shim reinforcement laminated between the two piezoelectric layers is an economical approach to producing a rugged actuator

Piezoelectric Bending Transducer (Q220-H4BR-1305YB) Meta||Mass (grams)||20.8 The bending disks bow inA 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.
