Fabrication of fluid-compatible trilayer cantilevers with integrated piezoelectric actuators

Luis Guillermo Villanueva Torrijo, Georg Fantner, Matthias Neuenschwander, Damien Maillard, Nahid Hosseini, Mustafa Kangül

Microcantilevers are popular transducers thanks to their simple design and a high sensitivity. In many applications, the cantilevers need to be actuated, either to induce a controlled deflection or to excite the resonance. This can be achieved with integra ...
