d33 mode piezoelectric diaphragm based acoustic transducer with high sensitivity

Sensors and Actuators A: Physical, 2013
Abstract This paper presents the design, fabrication, and characterization of an acoustic transducer using a piezoelectric freestanding bulk diaphragm as the sensing element. The diaphragm bearing the spiral electrode operates in d 33 mode, which allows the in-plane deformation of the diaphragm to be converted to the out-of-plane deformation and ...

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 ...

Design and performance evaluation of a d33-mode piezocomposite electricity generating element

Journal of Mechanical Science and Technology, 2014
Energy harvesting using smart materials and, in particular, piezoelectric material has been a very hot subject for several decades. The brittleness and low performance of PZT, which is widely used for energy harvesting applications, were considered a weakness.

Giant piezoelectric d33 coefficient in ferroelectric vanadium doped ZnO films

Applied Physics Letters, 2008
A giant electromechanical d33 coefficient 110pC∕N is obtained in ferroelectric V-doped ZnO films, which is nearly one order of magnitude higher than that of undoped samples. It is considered that the switchable spontaneous polarization induced by V dopants and the accompanying relatively high permittivity should be responsible for the enhancement of ...
