The flexoelectric effect is simply defined as the coupling between the strain gradient and
polarization in solid dielectrics. It may be seen as an alternative transduction mechanism to …

Previous work has shown that dielectrophoretic body forces resulting from permittivity and
conductivity heterogeneities only partially contribute to the overall electromechanical …

Pure polyurethane and nanocomposite carbon black (CB) polyurethane solutions were
deposited by spin-coating on a silicon substrate using gold as the adhesion layer and …

Polyurethane (PU) exhibit very high electromechanical activity, and has a great interest for a
wide range of transducer and actuator applications. It has been recently pointed out that this …

All dielectric materials have electroactivity, ie, the capability of changing their dimension or
shape in response to an applied electric field.(Dang et al, 2012) The electroactive polymer …

Electromechanical properties in polymers can be employed to create a large number of sen‐-
sors and actuators [1-2]. For example they could replace the piezoelectric materials common …

Tous les matériaux diélectriques possèdent une électroactivité, c'est-à-dire l'aptitude à
changer de dimension ou de forme en réponse à un champ électrique appliqué (Dang et al …

Dans le domaine des systèmes communicants, les antennes accordables (agiles) en
fréquence suscitent un intérêt croissant en raison de la prolifération des standards de …
