Taming the viscoelastic creep of dielectric elastomer actuators

Herbert Shea, Samuel Rosset, Alexandre Poulin

We present a simple open-loop method to suppress the viscoelastic drift of dielectric elastomer actuators (DEAs). Viscoelastic creep is one of the drawbacks of DEAs, especially when made with acrylic elastomer membranes (VHB). This leads to a time-dependen ...

Effects of a neuromuscular controller on a powered ankle exoskeleton during human walking

Daniel Renjewski, Auke Ijspeert, Arash Arami, Florin Dzeladini, Amy Roning Wu

Wearable devices to assist abnormal gaits require controllers that interact with the user in an intuitive and unobtrusive manner. To design such a controller, we investigated a bio-inspired walking controller for orthoses and prostheses. We present (i) a S ...
