Experimental investigation of the reliability of Printed Circuit Board (PCB)-embedded power dies with pressed contact made of metal foam

A Printed Circuit Board (PCB)-embedding process using pressed metal foam to connect the top-side pads of power dies is considered. The manufacturing process, simple and highly cost-effective, is described in detail; samples are manufactured and…

Dynamic Magnetostriction of CoFe2O4 and Its Role in Magnetoelectric Composites

Applications of magnetostrictive materials commonly involve the use of the dynamic deformation, i.e., the piezomagnetic effect. Usually, this effect is described by the strain derivative ∂λ=∂H, which is deduced from the quasistatic magnetostrictive…

Microfluidic device using reusable parylen-pdms packaging for the red blood cell transit time analysis in mechanical constrictions, using impedance measurement

In this paper, a micro-device dedicated to the analysis of the Red Blood Cell (RBC) deformability is proposed. It is based on PDMS microfluidic channels mimicking the flowing in the capillary vascular network. The RBC transit time within the…

Synthèse, caractérisation et modélisation de matériaux multiferroiques (magnétoélectriques) composites massifs

The direct magnetoelectric effect is defined by the modification of the electric polarization induced by a magnetic field. Although this effect exists intrinsically in some materials, here we study the extrinsic effect, where the magnetoelectric…
