Standards for dielectric elastomer transducers

Herbert Shea, Samuel Rosset, Claire Jean-Mistral

Dielectric elastomer transducers consist of thin electrically insulating elastomeric membranes coated on both sides with compliant electrodes. They are a promising electromechanically active polymer technology that may be used for actuators, strain sensors ...

Variable Stiffness Actuator for Soft Robotics Using Dielectric Elastomer and Low-Melting-Point Alloy

Dario Floreano, Herbert Shea, Samuel Rosset, Jun Shintake, Bryan Edward Schubert

A novel variable stiffness actuator composed of a dielectric elastomer actuator (DEA) and a low-melting-point-alloy (LMPA) embedded silicone substrate is demonstrated. The device which we call variable stiffness dielectric elastomer actuator (VSDEA) enable ...

Interfacing dielectric elastomer actuators with liquids

Herbert Shea, Samuel Rosset, Alexandre Poulin, Luc Maffli

Methods and materials for liquid encapsulation in thin (19 μm) silicone membranes are presented in this work. A set of 12 liquids including solvents, oils, silicone pre-polymers and one ionic liquid are experimentally tested. We show that all selected liqu ...

Tunable millimeter-wave phase shifter based on dielectric elastomer actuation

Herbert Shea, Julien Perruisseau-Carrier, Samuel Rosset, Pietro Romano

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 ...

Characterization of piezoelectric material for micro thermal harvesters

Paul Muralt, Emilie Catherine Sylviane Trioux

This paper presents the first realizations of a novel concept for thermal energy harvesting at micro scale. The devices proposed here are based on a two-step transduction combining thermo-mechanical and piezoelectric conversion. In this contribution, we pr ...

Dielectric Elastomer Actuators for soft-grasping

Dario Floreano, Herbert Shea, Samuel Rosset, Jun Shintake, Bryan Edward Schubert

We demonstrate here a configuration of soft actuator which has several features such as, being completely soft, simple, thin, foldable, and stretchable while having uni/bidirectional bending actuation. Theoretically the actuation can be extended to multidi ...

Improved electromechanical behavior in castable dielectric elastomer actuators

Herbert Shea, Samuel Rosset, Samin Akbari

Non-viscoelastic castable elastomers are replacing the polyacrylate VHB films in the new generations of dielectric elastomer actuators (DEAs) to achieve fast and reliable actuation. We introduce the optimum prestretch conditions to enhance the electromecha ...
