AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
Dielectric elastomers are highly promising as functional materials for the rapidly developing field of flexible actuator and generator technology. They offer a unique combination of low densities and large reversible deformations of up to more than 100% in ...
A novel method allowing rapid production of reliable composites with increased dielectric constant and high dielectric strength for dielectric elastomer actuators (DEA) is reported. The promising approach using composites of conductive particles and insula ...
Ferroelectric ceramic – polymer composites have a unique mix of electrical and mechanical properties. Piezoelectric and pyroelectric activity, a wide range of dielectric constants and high breakdown strength are combined with mechanical flexibility, formab ...
Piezoelectricity is the propriety of materials that relates mechanical deformation as a function of applied voltage and vice-versa. The advantage of using these materials as actuators is the fast response and low power consumption when compared with tradit ...
Electrostatically driven MEMS devices commonly operate with electric fields as high at 108 V/m applied across the dielectric between electrodes. Even with the best mechanical design, the electrical design of these devices has a large impact both on perform ...

The influence of film thickness on the material properties of aluminum nitride (AlN) thin films deposited on Pt(111) electrodes has been investigated experimentally by means of x-ray diffraction, dielectric response, atomic force microscopy, interferometry ...
The low frequency mechanical and dielectric behavior of three different elastomers has been investigated by dynamic mechanical analysis and dielectric spectroscopy, with the aim of accounting for the frequency dependence of the characteristics of the corre ...
The miniaturization of dielectric elastomer actuators requires compliant electrodes that are clean, reliable, and that can be easily patterned on a mm or μm scale. Carbon-based electrodes, which are commonly used to make large-scale actuators, are not well ...
