Properties of piezoceramic materials in high electric field actuator applications
Binal P Bruno, Ahmed Raouf Fahmy, Moritz Stürmer +2
In this paper, we compare the performance of 8 PZT ceramics and one PMN-PT material for typical bending actuator applications. This includes the measurement of non-linear transvers…

Topological in-plane polarized piezo actuation for compact adaptive lenses with aspherical correction
Florian Lemke, Moritz Stürmer, Ulrike Wallrabe +1
In this contribution, we investigate the effects of using in-plane polarized piezo actuators with topological buckling displacement to drive glass-piezo composite membranes for ada…

Single-Sided Contacting of Out-of-Plane Polarized Piezo Films for Fluid Membrane Lenses
Moritz Stürmer, Matthias C. Wapler, Ulrike Wallrabe
We present an adaptive lens which tunes its focal length with a glass membrane that is deformed by an integrated piezo bending actuator. A particular challenge in the fabrication o…
