Graph Chatbot

Chattez avec Graph Search

Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.

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.

Inkjet printing of carbon black electrodes for dielectric elastomer actuators

Herbert Shea, Samuel Rosset, Samuel Schlatter

Inkjet printing is an appealing technique to print electrodes for Dielectric Elastomer Actuators (DEAs). Here we present the preparation and ink-jet printing of a carbon black electrode mixture and characterise its properties. Carbon black has been used ex ...

Dielectric elastomer actuator for the measurement of cell traction forces with sub-cellular resolution

Herbert Shea, Michael James Henry Smith, Samuel Rosset, Alexandre Poulin

We report on the use of dielectric elastomer actuators (DEAs) to measure the traction force field of cells with subcellular resolution. The study of cellular electrochemical and mechanical response to deformation is an important area of research, as mechan ...

Multifunctional shape memory electrodes for dielectric elastomer actuators enabling high holding force and low-voltage multisegment addressing

Herbert Shea, Samuel Rosset, Nadine Besse, David James McCoul

Dielectric elastomer actuators (DEAs) are an attractive form of electromechanical transducer, possessing high energy densities, an efficient design, mechanical flexibility, high speed, and noiseless operation. They have been incorporated into a variety of ...

Fabrication process of silicone-based dielectric elastomer actuators

Herbert Shea, Samuel Rosset, Samuel Schlatter

This contribution demonstrates the fabrication process of dielectric elastomer transducers (DETs). DETs are stretchable capacitors consisting of an elastomeric dielectric membrane sandwiched between two compliant electrodes. The large actuation strains of ...
