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
Flow-through sensor based on piezoelectric MEMS resonator for the in-line monitoring of wine fermentation
TL;DR: In this paper, an AlN-based piezoelectric micro-resonator was designed to serve as a density sensor, resonantly excited in the 4th-order roof tile-shaped vibration mode.
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.
