Young modulus and Poisson ratio of PZT thin film by Picosecond Ultrasonics

F. Casset, A. Devos, S. Sadtler, A. Le Louarn, P. Emery, G. Le Rhun, P. Ancey, S. Fanget, E. Defay

Thin-film sol-gel Pb(Zr 0.52 , Ti 0.48 )O 3 (PZT) can be used in many actuator applications thanks to its high piezoelectric coefficients. The accurate knowledge of its mechanical properties such as Young modulus (E) and Poisson ratio (ν ν) or stiffness matrix is a key point for predictive design,…

Influence of 1-3 piezocomposite fabrications on lateral modes

Rémi Rouffaud, Anne-Christine Hladky, Maï Pham-Thi, Claire Bantignies, Franck Levassort

—Properties of 1-3 piezocomposites with periodic structure were characterized. This material can be typically fabricated in using the " dice and fill " method (DFM) and two phases were used (PMN-34.5PT ceramic and epoxy resin). The corresponding numerical simulations allowed to study the…

AlN/IDT/AlN/Sapphire as packageless structure for SAW applications in harsh environments

Ouarda Legrani, Omar Elmazria, A. Bartasyte, Thierry Aubert, Abdelkrim Talbi

Packageless heterostructure AlN/IDT/AlN/Sapphire was investigated as a solution protection of the interdigital transducer against agglomeration phenomena at high temperature. For this purpose, the performance of conventional IDT/AlN/Sapphire and protected AlN/IDT/AlN/Sapphire heterostructures were…

Reflections on Learning Mathematics in Physics Phenomenology and Historical Conceptual Streams.

Maria Mellone, Raffaele Pisano

Although several efforts produced by new mathematical education approaches for improving education systems and teaching, yet the results are not sufficient to adsorb the totality of innovations proposed, both in the contents and management. In this sense constructive debates and new ideas were…

Etude analytique, numérique et expérimentale d’écoulements générés par parois mobiles en microfluidique - Application aux micropompes, Analytical, numerical and an experimental study of flows generated by moving boundaries in microfluidics - Application to micropumps

Christophe Frankiewicz

A l’heure actuelle, la microfluidique est une science en plein développement ayant un besoin croissant de dispositifs permettant de générer des écoulements aux échelles micrométriques. Les phénomènes physiques mis en jeu lors du mouvement d’un fluide sont en effet majoritairement gouvernés par la…, Currently, microfluidic is a science field in constant development with an increasing need of devices able to generate flows at the micrometer order. At these length scales, physical phenomenons occurring in a moving fluid are mainly governed by its viscosity (low Reynolds number) contrary to…
