Journal ArticleDOI
Static and dynamic characterization of AlN and nanocrystalline diamond membranes
Fabian Knöbber,Fabian Knöbber,Verena Zürbig,Verena Zürbig,N. Heidrich,Jakob Hees,R. E. Sah,M. Baeumler,Steffen Leopold,Daniel Pätz,Oliver Ambacher,Oliver Ambacher,Vadim Lebedev +12 more
TL;DR: In this article, the Young's modulus E and residual stress σ are obtained by wafer bow measurements of thin films as well as by bulge experiments and vibration measurements of freestanding membranes.
Journal ArticleDOI
Corrugated piezoelectric membranes for energy harvesting from aperiodic vibrations
N. Heidrich,Fabian Knöbber,Fabian Knöbber,Vladimir Polyakov,Volker Cimalla,Wilfried Pletschen,R. E. Sah,Lutz Kirste,Steffen Leopold,S. Hampl,Oliver Ambacher,Oliver Ambacher,Vadim Lebedev +12 more
TL;DR: In this paper, non-resonant piezoelectric micro-energy-harvesters based on corrugated membranes made from aluminium nitride were designed to respond efficiently to aperiodic mechanical impact at low repetition rates.
Journal ArticleDOI
Electrostatically coupled vibration modes in unimorph complementary microcantilevers
Vadim Lebedev,N. Heidrich,Fabian Knöbber,R. E. Sah,Wilfried Pletschen,B. Raynor,Vladimir Polyakov,V. Cimalla,Oliver Ambacher +8 more
TL;DR: In this paper, the authors demonstrate piezoelectrically actuated, electrically tuneable resonator systems based on coupled micromechanical oscillators operating in a flexural vibration mode.
Journal ArticleDOI
AlN based microgenerators for powering implantable sensor devices
O. Bludau,C.-C. Röhlig,C.-C. Röhlig,Fabian Knöbber,Fabian Knöbber,Lutz Kirste,R. E. Sah,Rachid Driad,Wilfried Pletschen,Vadim Lebedev,Volker Cimalla +10 more
TL;DR: In this article, the authors report on microstructures made of AlN for the use as piezoelectric microgenerators in energy harvesting applications and show that due to the constant d33 piezo coefficients of > 5 pm/V, AlN films are well suited for the integration in cantilever structures for powering of low-consumption sensor networks.
Proceedings ArticleDOI
Tunable compound eye cameras
TL;DR: In this article, the authors present design and realization concepts for thin compound eye cameras with enhanced optical functionality based on facets with individually tunable focus lengths and viewing angles for scanning of the object space.
