Observation of Charge Compensated Polarization Zones in Polyvinylindenfluoride ( Pvdf ) Films by Piezoelectric Acoustic Step - Wave Response
A tugh resolution (2/am) acousUc step-wave probing techmques has been developed to investigate the lnhomogeneous dtstnbutlon of the piezoelectric response of incompletely corona poled 85/am ttuck PVDF films We observe persistent polanzaUon zones or layers of 20-40/am width within the films wtuch are electrostatlcally compensated by charge accumulaUon at the polanzaUon zone boundaries The zone d...

متن کاملPVD-grown antibacterial Ag-TiN films on piezoelectric PVDF substrates for sensor applications
This work reports on Ti1-xAgx and Ag-TiNx electrodes deposited by dc/pulsed dc magnetron sputtering at room temperature on poly (vinylidene fluoride) (PVDF) with the purpose to develop sensors for prosthesis. In Ti1-xAgx electrodes, silver content was varied from 0-100 at. %; and for Ag-TiNx electrodes, the nitrogen content was varied between 34 to 43 at. % and the Ti/Ag ratio changed from 12.2...
متن کاملDefect Modes in Multilayered Piezoelectric Structures
Abstract—Propagation of electro-elastic waves in a piezoelectric waveguide with finite stacks and a defect layer is studied using a modified transfer matrix method. The dispersion equation for a periodic structure consisting of unit cells made up from two piezoelectric materials with metallized interfaces is obtained. An analytical expression, for the transmission coefficient for a waveguide wi...
متن کاملPlate modes in piezoelectric multilayered structures
2014 Recent experiments have shown that interdigital transducers can couple strongly to plate modes in piezoelectric composite membranes. In this paper the dispersive properties and the piezoelectric coupling (039403BD/03BD) to these plate modes are presented The various types of modes are identified and related to crystalline symmetry. Results are given for stiffened-shear modes in zinc oxide ...
