Electrical de-poling and re-poling of relaxor-PbTiO3 piezoelectric single crystals without heat treatment

open access: yesNature Communications
Re-poling of unexpected partially depoled piezoelectric materials conventionally needs to be first fully depoled through annealing above their Curie temperature to revive piezoelectric performances. Here, we investigated de-poling and re-poling of Pb(In1/

A far from equilibrium state developed from pulse poling for high performance piezoelectric transducers [PDF]

open access: yesNano Convergence
Creating a piezoelectric or pyroelectric material from a ferroelectric material requires aligning its ferroelectric domains to achieve a remanent polarization. This complex process involves nucleating/growing domain structures and inducing a macroscopic,

Toward the pole [PDF]

open access: yesJournal of High Energy Physics, 2020
Abstract We study the analytic structure of semiclassical conformal blocks, namely of the 1-point conformal block on the torus and of the 4-point conformal block on the sphere, as functions of the intermediate dimension. We interpret their discontinuities, which can be revealed with the use of a particular resummation procedure ...

Leaky-modes excitation in thermally poled nanocomposite glass and their exploitation for saturable absorption [PDF]

open access: yes, 2010
Thermal poling is used to create a reduced index layer in a soda-lime/nanocomposite film. Leaky-modes have been exploited to enhance interaction of light with Au-nanoparticles and demonstrate saturable absorption characteristics in line with state-of-the-

Investigation of Contact Poling Process in Thin Films of Polymer Doped with Disperse Red 1 Dye [PDF]

open access: yesعلوم و تکنولوژی پلیمر, 2007
Thin films of polymer doped with nonlinear optical organic dye, Disperse Red 1, at thickness of 1 to 2 micrometers, were prepared and studied. In order to induce an axial and orientational alignment of dye molecules within polymer matrix, a contact ...

Multiplex Sensing Electronic Skin Based on Seamless Fully Printed Stretchable Piezoelectric Devices

open access: yesAdvanced Sensor Research, 2023
Wearable skin mountable devices, more than flexibility, require conformability, stretchability, and a high water vapor transmission rate, so that the perspiration processes are not blocked, to assure comfort and stability of use in contact with living ...

An Investigation into the Role of Capping on Second Harmonic Generation from Nonlinear Organic Polymer and Guest-Host Thin Films by In-situ Poling [PDF]

open access: yes, 2016
In attempts to fabricate thermally stable second-order nonlinear polymer thin films, we have investigated the second harmonic generation (SHG) from both nonlinear polymer and guest-host thin films. We have also investigated the role of capping on the SHG,

Recent advances in the preparation of PVDF-based piezoelectric materials

open access: yesNanotechnology Reviews, 2022
In recent years, PVDF(polyvinylidene fluoride) and its copolymers have attracted great attention in the development of energy-harvesting devices because of their unique properties such as good flexibility, environmental friendliness, high halogen and ...
