A Miniaturized Piezo Stack Impact Actuation Mechanism for Out-of-Plane Freely Moveable Masses
We present the prototype and analytical model of a miniaturized impact actuation mechanism, providing a fast out-of-plane displacement to accelerate objects against gravity, allowing for freely moving objects and hence for large displacements without the

A piezoelectric multilayer-stacked hybrid actuation/transduction system [PDF]
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.
