A finite element approach for modelling multilayer unimorph dielectric elastomer actuators with inhomogeneous layer geometry
High-strain actuators are an emerging technology akin to biological muscles. They are of engineering interest because they dispense with need for gearboxes, links and mechanisms. Paper uses finite-element techniques to define force, deflection and stress characteristics for optimised design of novel electroactive polymer (EAP) actuators. Paper was fast-tracked, made open-access and selected in 2012 Journal Highlights [tinyurl.com/gen-eng-21] due to "referee endorsement, novelty and scientific impact". Authors have since collaborated with consultant hand surgeon [Plastic Surgery and Burns Research Unit, University of Bradford] to design smart glove for hand rehabilitation using this type of actuator.
