Fabrication process of silicone-based dielectric elastomer actuators

Herbert Shea, Samuel Rosset, Samuel Schlatter, Oluwaseun Adelowo Araromi

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 ...

Low-loss Millimeter-wave Phase Shifters Based on Mechanical Reconfiguration

Juan Ramon Mosig, Herbert Shea, Julien Perruisseau-Carrier, Samuel Rosset, Pietro Romano, Oluwaseun Adelowo Araromi

We propose different concepts of mechanically reconfigurable true-time-delay phaseshifters using micro-actuators at millimeter-waves (MMW). The mechanical reconfiguration allows to achieve phase shift reconfiguration with very low losses. One of the propos ...

Maximizing the displacement of compact planar dielectric elastomer actuators

Herbert Shea, Samuel Rosset, Oluwaseun Adelowo Araromi

We present a model and its experimental validation for the optimization of the in-plane displacement of a rigid platform mounted on a compact dielectric elastomer actuator. Unlike the situation in which the mechanical prestretch of the membrane is maintain ...

Rollable Multisegment Dielectric Elastomer Minimum Energy Structures for a Deployable Microsatellite Gripper

Herbert Shea, Volker Gass, Samuel Rosset, Jun Shintake, Muriel Richard, Irina Gavrilovich, Oluwaseun Adelowo Araromi

Debris in space presents an ever-increasing problem for spacecraft in Earth orbit. As a step in the mitigation of this issue, the CleanSpace One (CSO) microsatellite has been proposed. Its mission is to perform active debris removal of a decommissioned nan ...

High-resolution, large-area fabrication of compliant electrodes via laser ablation for robust, stretchable dielectric elastomer actuators and sensors

Herbert Shea, Samuel Rosset, Oluwaseun Adelowo Araromi

A key element in stretchable actuators, sensors and systems based on elastomer materials are compliant electrodes. While there exist many methodologies for fabricating electrodes on dielectric elastomers, very few succeed in achieve high-resolution pattern ...

Model and design of dielectric elastomer minimum energy structures

Herbert Shea, Samuel Rosset, Jun Shintake, Oluwaseun Adelowo Araromi

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 ...

Tunable millimeter-wave phase shifter based on dielectric elastomer actuation

Herbert Shea, Julien Perruisseau-Carrier, Samuel Rosset, Pietro Romano, Oluwaseun Adelowo Araromi

A very low-loss tunable millimeter-wave phase shifter driven by dielectric elastomer actuators (DEAs) is presented. The device consists of a fixed coplanar waveguide (CPW) and two metallic loading strips suspended on an elastomer membrane. The horizontal o ...
