Effects of piezoelectric coupling on energy mapping of thickness-shear modes
IEEE Transactions on Ultrasonics, Ferroelectrics and Frequency Control, 2004Energy trapping of thickness-shear vibration modes in a partially electroded piezoelectric crystal plate of monoclinic symmetry is analyzed. Effects of piezoelectric coupling on energy trapping are examined. Results show that the effect of piezoelectric coupling is comparable to the effect of electrode mass and needs to be included in the analysis of ...

Cell Motility Probed by Noise Analysis of Thickness Shear Mode Resonators
Analytical Chemistry, 2006The quartz crystal microbalance (QCM) technique is an emerging bioanalytical tool to study the behavior of animal cells in vitro. Due to the high interfacial sensitivity of thickness shear mode (TSM) resonators it is possible to monitor the formation and breakage of cell-matrix interactions and changes in viscoelasticity of the cell bodies, as well as ...

Thickness-shear modes of an elliptical, contoured at-cut quartz resonator
IEEE Transactions on Ultrasonics, Ferroelectrics, and Frequency Control, 2013We study free vibrations of an elliptical crystal resonator of AT-cut quartz with an optimal ratio between the semi-major and semi-minor axes as defined by Mindlin. The resonator is contoured with a quadratic thickness variation. The scalar equation for thickness-shear modes in an AT-cut quartz plate by Tiersten and Smythe is used. Analytical solutions

Theoretical analysis of a ceramic plate thickness-shear mode piezoelectric transformer
IEEE Transactions on Ultrasonics, Ferroelectrics and Frequency Control, 2009We perform a theoretical analysis on a ceramic plate piezoelectric transformer operating with thickness-shear modes. Mindlin's first-order theory of piezoelectric plates is employed, and a forced vibration solution is obtained. Transforming ratio, resonant frequencies, and vibration mode shapes are calculated, and the effects of plate thickness and ...

High-Power, Multioutput Piezoelectric Transformers Operating at the Thickness-Shear Vibration Mode
IEEE Transactions on Ultrasonics, Ferroelectrics and Frequency Control, 2004In this study, a piezoelectric transformer operating at the thickness shear vibration mode and with dual or triple outputs is proposed. It consists of a lead zirconate titanate (PZT) ceramic plate with a high mechanical quality factor Qm and a size of 120 x 20 x 4 mm3. The PZT ceramic plate is poled along the width direction.

Piezoelectric Ceramics Used for Thickness Shear Mode and Their Applications
Japanese Journal of Applied Physics, 1982Solid solution Pb[Zr, Ti, (Mn1/3Sb2/3)]O3 ceramics with small amounts of metal oxides show large electromechanical coupling factors (>0.5), high mechanical Q factors (>1000), small temperature coefficients of frequency constant (<±10 ppm/°C) and low aging rates of frequency constant (<0.01%/time decade) in regard to thickness shear ...

Magnetoelectric effect at thickness shear mode in ferrite-piezoelectric bilayer
Applied Physics Letters, 2013This manuscript discusses first observation of magnetoelectric (ME) coupling at thickness shear modes in a magnetostrictive-piezoelectric bilayer. The measured value of magnetoelectric voltage coefficient is optimized by adjusting the geometry of layers.

Thickness-shear mode quartz crystal resonators in viscoelastic fluid media
Journal of Applied Physics, 2000An extended Butterworth–Van Dyke (EBVD) model to characterize a thickness-shear mode quartz crystal resonator in a semi-infinite viscoelastic medium is derived by means of analysis of the lumped elements model described by Cernosek et al.

Novel analog readout electronics for microacoustic thickness shear-mode sensors
IEEE Sensors Journal, 2005In this paper, a novel purely analog electronic readout circuit for sensors based on thickness shear-mode (TSM) resonators is introduced. This system can, e.g., be used for viscosity sensing of liquids, even if the liquid shows a comparatively high viscosity. In contrast to conventionally utilized oscillator circuits, the present circuit eliminates the

Thickness-shear mode acoustic wave sensors and flow-injection analysis
Analytica Chimica Acta, 1992Abstract A feasibility study of the combination of the flow-injection analysis (FIA) technique with the piezoelectric acoustic wave sensor (thickness-shear mode, TSM) is described. Flow-injection systems provide a method to relate the hydrodynamic response of the sensor to the concentration-time profile of the analyte produced by the dispersion ...
