A method for producing a device adapted to be implanted into the human body for purposes such as neural stimulation, sensing or the like, and device produced according to said method, said method comprising: providing a stretchable layer or membrane (21) o ...
2016Fully printed 3 microns thick dielectric elastomer actuator
Herbert Shea, Samuel Rosset, Alexandre Poulin
In this work we present a new fabrication technique to print thin dielectric elastomer actuators (DEAs), reducing the driving voltage below 300 V while keeping good actuation performance. With operation voltages in the kV-range, standard DEAs are limited i ...
Spie-Int Soc Optical Engineering2016Fabrication 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 ...
Journal of Visualized Experiments2016Contribution of polymeric materials to progress in xenotransplantation of microencapsulated cells - A review
Sandrine Gerber, François Rémi Pierre Noverraz, Jutta Christine Wandrey, Redouan Mahou, Solène Marcelle Françoise Marie Passemard
Cell microencapsulation and subsequent transplantation of the microencapsulated cells require multidisciplinary approaches. Physical, chemical, biological, engineering, and medical expertise has to be combined. Several natural and synthetic polymeric mater ...
2016Maximizing strain in miniaturized dielectric elastomer actuators
We present a theoretical model to optimise the unidirectional motion of a rigid object bonded to a miniaturized dielectric elastomer actuator (DEA), a configuration found for example in AMI’s haptic feedback devices, or in our tuneable RF phase shifter. Re ...
Spie-Int Soc Optical Engineering2015The motion of a deforming capsule through a corner
A three-dimensional deformable capsule convected through a square duct with a corner is studied via numerical simulations. We develop an accelerated boundary integral implementation adapted to general geometries and boundary conditions. A global spectral m ...
Cambridge University Press2015Pad printing 1-10 mm thick elastomer membranes for DEAs
Herbert Shea, Samuel Rosset, Alexandre Poulin
We present a technique for stamping patterned silicone elastomer membranes with thicknesses ranging from 1 to 10 um. Silicone elastomers are becoming the material of choice for dielectric elastomer transducers. The variety of readily available materials, t ...
2015Dynein-Based Accumulation of Membranes Regulates Nuclear Expansion in Xenopus laevis Egg Extracts
Nuclear size changes dynamically during development and has long been observed to correlate with the space surrounding the nucleus, as well as with the volume of the cell. Here we combine an in vitro cell-free system of Xenopus laevis egg extract with micr ...
2015Soft compartmentalization: Combining droplet-based microfluidics with freely accessible cells
Droplet‐based microfluidics allows the generation and manipulation of many independent microreactors (pico‐ to nanoliter volumes) optionally hosting human cells. However, one limitation is that mammalian cells within droplets are not fully accessible from ...
2015Printing low-voltage dielectric elastomer actuators
Herbert Shea, Samuel Rosset, Alexandre Poulin
We demonstrate the fabrication of fully printed thin dielectric elastomer actuators (DEAs), reducing the operation voltage below 300V while keeping good actuation strain. DEAs are soft actuators capable of strains greater than 100% and response times below ...
