930Hz Piezoelectric Bender 20x8x0.8mm Multilayer

930Hz Piezoelectric Benders

Product Description

Using all ceramic design to replace the traditional bimorph, ceramic + metal (polymer / carbon fiber) + ceramic structure design, making its output much greater than ordinary bimorph. The bimorph has a double-layer design. When voltage is applied, one layer shrinks and the other expands, resulting in deformation.

These bimorphs are fabricated by tape casting and co firing techniques with high reliability and are ideal for optical choppers, pipe benders, pumping and metering applications.
