Green piezoelectric for autonomous smart textile

Danick Briand, Etienne Pierre Lemaire, Christopher John Borsa

In this work, the fabrication of Rochelle salt based piezoelectric textiles are shown. Structures composed of fibers and Rochelle salt are easily produced using green processes. Both manufacturing and the material itself are really efficient in terms of en ...

High Piezoelectric Longitudinal Coefficients in Sol-gel PZT Thin Film Multilayers

Paul Muralt, Silviu Cosmin Sandu, Antonia Neels, Alex Dommann, Andrea Mazzalai, Nachiappan Chidambaram, Davide Balma

A five-layer stack of lead zirconate titanate (PZT) thin films with Pt electrodes was fabricated for potential applications in nanoactuator systems. The 1 mu m thick PZT films were deposited by a sol-gel technique, the platinum electrodes by sputtering. Th ...

An in situ diffraction study of domain wall motion contributions to the frequency dispersion of the piezoelectric coefficient in lead zirconate titanate

Dragan Damjanovic

The contribution of non-180 degrees domain wall displacement to the frequency dependence of the longitudinal piezoelectric coefficient has been determined experimentally in lead zirconate titanate using time-resolved, in situ neutron diffraction. Under sub ...
