Journal ArticleDOI
Piezoelectric MEMS resonator-based oscillator for density and viscosity sensing
Tomas Manzaneque,Víctor Ruiz-Díez,J. Hernando-García,E. Wistrela,M. Kucera,Ulrich Schmid,José Luis Sánchez-Rojas +6 more
TL;DR: In this paper, an oscillator featuring an in-liquid piezoelectric microplate resonator as the frequency-selective element was used for density and viscosity sensing.
Journal ArticleDOI
Design-dependent performance of self-actuated and self-sensing piezoelectric-AlN cantilevers in liquid media oscillating in the fundamental in-plane bending mode
M. Kucera,E. Wistrela,G. Pfusterschmied,Víctor Ruiz-Díez,Tomas Manzaneque,J. Hernando-García,José Luis Sánchez-Rojas,Artur Jachimowicz,Artur Jachimowicz,Johannes Schalko,Achim Bittner,Ulrich Schmid +11 more
TL;DR: In this article, the electrical performance of micromachined piezoelectric cantilevers having different designs is investigated in liquid environment, thus making most beneficially use of their self-actuated and self-sensing capability.
Journal ArticleDOI
Characterization of a roof tile-shaped out-of-plane vibrational mode in aluminum-nitride-actuated self-sensing micro-resonators for liquid monitoring purposes
M. Kucera,E. Wistrela,G. Pfusterschmied,Víctor Ruiz-Díez,Tomas Manzaneque,José Luis Sánchez-Rojas,Johannes Schalko,Achim Bittner,Ulrich Schmid +8 more
TL;DR: In this article, an advanced out-of-plane bending mode for aluminum-nitride (AlN)-actuated cantilevers was presented. But the authors focused on the performance of the bending mode in deionized water at a low resonance frequency of 336 kHz.
Journal ArticleDOI
ScAlN MEMS Cantilevers for Vibrational Energy Harvesting Purposes
P. M. Mayrhofer,C. Rehlendt,M. Fischeneder,M. Kucera,E. Wistrela,Achim Bittner,Ulrich Schmid +6 more
TL;DR: In this paper, the authors demonstrate the fabrication and characterization of piezoelectric cantilevers with AlN and ScAlN thin films for evaluation of their energy harvesting performance.
Journal ArticleDOI
Temperature dependent performance of piezoelectric MEMS resonators for viscosity and density determination of liquids
G. Pfusterschmied,M. Kucera,E. Wistrela,Tomas Manzaneque,Víctor Ruiz-Díez,José Luis Sánchez-Rojas,Achim Bittner,Ulrich Schmid +7 more
TL;DR: In this article, the performance of piezoelectric MEMS resonators for viscosity and density measurements at elevated temperatures is reported, with a mean deviation of about 1.04% at 100 °C for all the liquids investigated.
