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.

This thesis contributes to the field of Dielectric Elastomer Actuators (DEAs). DEAs are electrostatically driven soft actuators that are fast, capable of generating large actuation strains, high forces, and present high power density. A wide range of appli ...

Head‐mounted displays for virtual reality (VR) and augmented reality (AR) allow users to see highly realistic virtual worlds. The wearable haptics that enable feeling and touching these virtual objects are typically bulky, tethered, and provide only low fi ...

Insects are a constant source of inspiration for roboticists. Their compliant bodies allow them to squeeze through small openings and be highly resilient to impacts. However, making subgram autonomous soft robots untethered and capable of responding intell ...

A high‐voltage flip‐flop combining two self‐powered soft sensors with a flexible high‐voltage thin film transistor (HVTFT) is reported, and is used to electrically latch dielectric elastomer actuators (DEAs) in zero and high‐strain states. Two touch‐actuat ...

We present a stretchable tunable transmission grating in which the optical surface serves simultaneously as an electrode for electrostatic actuation. Tunable optics based on elastomers allow for a large tuning range, but integrating an actuator generally s ...
