Herbert Shea, Fabio Beco Albuquerque
An actuator (22) comprises at least one actuator body (32) of dielectric elastomeric material and two electrodes (34, 36) being attached to opposite surfaces of the actuator body (32), respectively. At least one of the actuator body (32) and at least one o ...
2022Conformable neural interfaces : from engineering stretchability at the micro-scale to translational applications
Recently, flexible and soft bioelectronic interfaces have been proposed as a solution to improve existing neural interfaces that currently present mechanical mismatch with the soft tissue. These are devices fabricated with thin polymeric or elastomeric bac ...
EPFL2022Multifunctional Hyperelastic Structured Surface for Tunable and Switchable Transparency
Romain Christophe Rémy Fleury, Rayehe Karimi Mahabadi, Taha Goudarzi
We leverage the crucial hyperelastic properties of a multifunctional structured surface to optimize the reconfigurability of the electromagnetic transmission under large nonlinear mechanical deformations. This multiphysics, multifunctional, hyperelastic st ...
2021Synthesis of solvent-free processable and on-demand cross-linkable dielectric elastomers for actuators
Dielectric elastomer actuators (DEAs) have gained growing interest during the last decade from both the scientific community and industry. However, the high operating voltages needed to drive these actuators reduce their application potential. To date, sev ...
ROYAL SOC CHEMISTRY2019Flexible support and enhanced groove geometries for gas lubricated bearings
Gas lubricated Herringbone-Grooved Journal Bearings (HGJB) are a promising solution to support high-speed rotors in oil-free turbo-machinery due to their compactness, relatively low losses, no need for lubrication and low wear.
Gas lubricated bearings, how ...
EPFL2019Soft And Wearable Transducers: Opportunities And Challenges For Daily Use
Soft bioelectronic interfaces are broadly defined as microfabricated devices, distributed over large-areas, and with mechanical properties suited to comply the soft and dynamic biological tissues. The hybrid integration and processing of materials ranging ...

Hierarchical porous structures have been gathering interest in different fields owing to their unique properties associated with their multi-scale features. The observation of natural materials brought new insights into the functionality of cellular materi ...
EPFL2018Small, fast and tough: an overview of our silicone-based actuators
At the Microsystems for Space Technologies Laboratory, EPFL, we design and manufacture miniaturised silicone-based dielectric elastomer actuators (DEAs). We love silicone, because even though the achievable strain is generally smaller than what you can get ...
2014Model and design of dielectric elastomer minimum energy structures
Herbert Shea, Samuel Rosset, Jun Shintake
Fixing a prestretched dielectric elastomer actuator (DEA) on a flexible frame allows transformation of the intrinsic in-plane area expansion of DEAs into complex three-dimensional (3D) structures whose shape is determined by a configuration that minimizes ...
Institute of Physics2014Pump it up
Herbert Shea, Samuel Rosset, Luc Maffli
We report on the use of zipping actuation applied to dielectric elastomer actuators to microfabricate mm-sized pumps. The zipping actuators presented here use electrostatic attraction to deform an elastomeric membrane by pulling it into contact with a rigi ...
