Model 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 ...

Giovanni De Micheli, Sandro Carrara, Catherine Dehollain, Camilla Baj-Rossi, Seyedeh Sara Ghoreishizadeh, Enver Gürhan Kilinç, Daniele Casarino
In this work, we show the realization of a fully-implantable device for monitoring free-moving small animals. The device integrates a microfabricated sensing platform, a coil for power and data transmission and two custom designed integrated circuits. The ...
Ieee-Inst Electrical Electronics Engineers Inc2014An instrument to obtain the correct biaxial hyperelastic parameters of silicones for accurate DEA modelling
Herbert Shea, Samuel Rosset, Luc Maffli, Simon Houis
The analytical formulas describing the behaviour of dielectric elastomer actuators (DEAs) are based on hyperelastic strain energy density functions. The analytical modelling of a DEA will only lead to meaningful results if the dielectric elastomer can be a ...
Spie-Int Soc Optical Engineering2014Interplay between cytoskeletal forces, membrane tension and shape in rapidly migrating cells
Cell migration is a fundamental process in all animal cells. The ability of cell to migrate is crucial for many pathological and physiological conditions such as morphogenesis, the immune response to inflammatory or vascular diseases and cancer metastasis. ...
EPFL2013Heated mask
Jürgen Brugger, Andreea Veronica Savu, Shenqi Xie
The invention concerns a method and a device wherein a stencil is provided with an integrated microhotplate on the stencil membrane to prevent aperture clogging, whereby the stencil can be locally heated up in order to minimize material condensation, remov ...
2013Mm-size bistable zipping dielectric elastomer actuators for integrated microfluidics
Herbert Shea, Samuel Rosset, Luc Maffli
We report on a new structure of Dielectric Elastomer Actuators (DEAs) called zipping DEAs, which have a set of unique characteristics that are a good match for the requirements of electrically-powered integrated microfluidic pumping and/or valving units as ...
Spie-Int Soc Optical Engineering2013Microfabrication and characterization of an array of dielectric elastomer actuators generating uniaxial strain to stretch individual cells
Cells regulate their behavior in response to mechanical strains. Cell cultures to study mechanotransuction are typically cm2 in area, far too large to monitor single cell response. We have developed an array of dielectric elastomer microactuators as a tool ...
2012The need for speed
Herbert Shea, Samuel Rosset, Pit Gebbers
Development of dielectric elastomer actuators has been mainly targeted towards achieving giant static strain with little attention paid to their response speed, which can, depending on materials used, be as long as tens of seconds. However, most of the pra ...
SPIE2012In situ evaluation of single-cell lysis by cytosol extraction observation through fluorescence decay and dielectrophoretic trapping time
We present a new method for lysis of single cells in continuous flow, where cells are sequentially trapped, lysed and released in an automatic process. Using optimized frequencies, dielectrophoretic trapping allows exposing cells in a reproducible way to h ...
Elsevier2012Dynamically deformable reflective membrane for laser beam shaping and smoothing
Nico de Rooij, Roland Andreas Bitterli, Jonathan Masson, Wilfried Noell
We show a laser beam shaping device made of a deformable continuous reflective membrane fabricated over a scanning stage. The combination of two actuator schemes enables shaping and smoothing of a laser beam with a unique compact device. It is designed to ...
