Time dependence of piezoelectric d33 coefficient of cellular ferroelectret polypropylene film
Applied Physics Letters, 2011Due 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, 2014Energy 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, 2008A 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 ...
