A piezoelectric multilayer-stacked hybrid actuation/transduction system [PDF]
Applied Physics Letters, 2011 A piezoelectric multilayer-stacked hybrid actuation/transduction system (stacked-HYBATS) is reported in this letter. It uses synergetic contributions from positive-strain and negative-strain piezoelectric multilayer-stacks to give displacements of about 3.5 times those of the same-sized piezoelectric flextensional actuator/transducer.
