Actuation capability of a dielectric elastomer balloon actuator
2016 12th IEEE International Conference on Control and Automation (ICCA), 2016Dielectric elastomers show great promise for soft actuators. As the allowable deformation range of dielectric elastomers is strictly limited by the material failures, the actuation ability of a dielectric elastomer actuator is accordingly bounded. Although the material failures have been well studied, little literature has been released regarding the ...

A Robust Multilayer Dielectric Elastomer Actuator
MRS Proceedings, 2015ABSTRACTWe recently fabricated and characterized a new class of multilayer dielectric elastomer films comprising alternating layers of two different polymers, at least one of which is an elastomer. The films discussed here contain THV (a terpolymer of poly(vinylidene fluoride)) and poly(ethylene octene) [EO] elastomer. The multilayer structure provides

Improved Materials for Dielectric Elastomer Actuators
Volume 1: Advanced Energy Systems; Advanced and Digital Manufacturing; Advanced Materials; Aerospace, 2008Dielectric elastomers are an emerging class of electroactive polymers for electromechanical transduction. A broad application of dielectric elastomer actuators (DEA) is limited by the high voltage necessary to drive such devices. The development of novel elastomers offering better intrinsic electromechanical properties is one way to solve the problem ...

Dielectric elastomer actuators for tactile displays
World Haptics 2009 - Third Joint EuroHaptics conference and Symposium on Haptic Interfaces for Virtual Environment and Teleoperator Systems, 2009In this paper we discuss dielectric elastomer actuators (DEA) as one of the most promising technologies in electroactive polymers (EAP). For tactile display applications a large number of actuator elements is essential. The multilayer technology presented here offers the possibility to build up independent actuators and arrays at a high density within ...
