Laser Doppler vibrometry for evaluating the piezoelectric coefficient d33 on thin film

Review of Scientific Instruments, 2006
The problem of electromechanical film characterization, and, in particular, the determination of the piezoelectric activities of thin films deposited on substrates, is of fundamental importance in the development of structures for microelectromechanical system (MEMS) applications.

Time dependence of piezoelectric d33 coefficient of cellular ferroelectret polypropylene film

Applied Physics Letters, 2011
Due to the inherent viscosity of polymer, piezoelectric response in the thickness direction (d33) of cellular ferroelectret films usually depends on the time of measurement. In this letter, the micromechanical theory of viscoelastic composite was extended to predict the time dependence of the overall piezoelectric d33 coefficient of voided charged ...

Enhancement on effective piezoelectric coefficient d33 of Bi3.15Dy0.85Ti3O12 ferroelectric thin films

Materials Letters, 2010
Abstract Effects of annealing temperature (600–800 °C) on microstructure, ferroelectric and piezoelectric properties of Bi 3.15 Dy 0.85 Ti 3 O 12 (BDT) thin films prepared by metal-organic decomposition were studied. The remnant polarization 2 P r and spontaneous polarization 2 P s (16.2 µC/cm 2 and 23.3 µC/cm 2 under 690 kV/cm), effective

Enhanced d33 value of Bi0.5Na0.5TiO3–(Ba0.85Ca0.15)(Ti0.90Zr0.10)O3 lead-free ceramics

Journal of Alloys and Compounds, 2012
Abstract (1 −  x )Bi 0.5 Na 0.5 TiO 3 – x (Ba 0.85 Ca 0.15 )(Ti 0.90 Zr 0.10 )O 3 [(1 −  x )BNT– x BCTZ] lead-free piezoelectric ceramics were prepared by a conventional solid reaction method. A stable solid solution is well formed between BNT and BCTZ.

Piezoelectric d33 coefficient of cellular polypropylene subjected to expansion by pressure treatment

Applied Physics Letters, 2004
The piezoelectric activity of charged cellular polypropylene films of originally 40 and 50μm thickness can be significantly increased by thickness expansion due to an exposure to high pressure for time periods of the order of hours. After such a treatment, the d33 coefficient, measured by quasistatic and interferometric methods, is found to be as high ...
