Surface polarization enhancement and switching properties of small ferroelectric particles

Laurent Baudry

We have studied the polarization switching in ferroelectric particles by using a time dependent Ginzburg Landau model. The surface effect is described by considering the polarization enhancement towards the surface. The influence of this phenomena and related bound charges field on switching…

Modal wave decoherence within a fluid layer with a rough surface

Catherine Potel, Michel Bruneau, Bruno Morvan, Jean-Louis Izbicki, Anne-Christine Hladky, Claude L. Depollier

The aim of the presentation is to study analytically the propagation of modal waves (like Lamb waves) in a rough fluid plate, in order to interpret the decay of Lamb modes which are observed experimentally and theoretically in solid plates with a rough interface. The analytical method employed here…

Piezoelectric micro-machined ultrasonic transducer (pMUT) for energy harvesting

Karim Dogheche, B. Cavallier, P. Delobelle, L. Hirsinger, S. Ballandras, Eric Cattan, Denis Remiens, M. Marzencki, B. Charlot, Skandar Basrour

Micro-electromechanical devices dedicated to energy scavenging purpose have yield an increasing interest for a few years. In this paper we report on the fabrication of PZT/Si piezoelectric micro-machined ultrasonic transducers (pMUT) first designed to ultrasonic imaging applications that may be…
