Investigation of Ethylene and Propylene Production from CO2 Reduction over Copper Nanocubes in an MEA-Type Electrolyzer

Previous work carried out in fully liquid environ-ments and at low current densities has demonstrated that highly uniform faceted copper nanocrystals display different selectivity profiles in CO2 reduction compared to polycrystalline copper. As part of ong ...

Influence of humidity, temperature and prestretch on the dielectric breakdown strength of silicone elastomer membranes for DEAs

Herbert Shea, Fabio Beco Albuquerque

Humidity, temperature and membrane prestretch influence the dielectric breakdown strength of elastomer membranes. These three factors thus also influence the maximum force and strain that dielectric elastomer actuators (DEAs) can generate, as the Maxwell p ...

Towards fast, reliable, and manufacturable DEAs: miniaturized motor and Rupert the rolling robot

Herbert Shea, Samuel Rosset

Dielectric elastomer transducers (DETs) are known for their large strains, low mass and high compliance, making them very attractive for a broad range of applications, from soft robotics to tuneable optics, or energy harvesting. However, 15 years after the ...

Thin-film dielectric elastomer sensors to measure the contraction force of smooth muscle cells

Herbert Shea, Cristina Martin Olmos, Samuel Rosset, Alexandre Poulin, Mélanie Favre, Martha Liley

The development of thin-film dielectric elastomer strain sensors for the characterization of smooth muscle cell (SMC) contraction is presented here. Smooth muscle disorders are an integral part of diseases such as asthma and emphysema. Analytical tools ena ...

Zipping dielectric elastomer actuators: characterization, design and modeling

Herbert Shea, Samuel Rosset, Luc Maffli

We report on miniature dielectric elastomer actuators (DEAs) operating in zipping mode with an analytical model that predicts their behavior. Electrostatic zipping is a well-known mechanism in silicon MEMS to obtain large deformations and forces at lower v ...

Mm-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 ...

Effect of mechanical parameters on dielectric elastomer minimum energy structures

Dario Floreano, Herbert Shea, Samuel Rosset, Jun Shintake

Soft robotics may provide many advantages compared to traditional robotics approaches based on rigid materials, such as intrinsically safe physical human-robot interaction, efficient/stable locomotion, adaptive morphology, etc. The objective of this study ...

Zipping it up: DEAs independent of the elastomer's electric breakdown field

Herbert Shea, Luc Maffli, Pit Gebbers, Christoph Stamm

We demonstrate here an alternative dielectric elastomer actuator (DEA) structure, which relies on the compliant nature of elastomer membranes but does not require any electric field in the elastomer. Our elastomer zipping device is a macroscopic version of ...
