Simulation of Networked Dielectric Elastomer Balloon Actuators
IEEE Robotics and Automation Letters, 2016A dielectric elastomer is able to act as an actuator when subjected to an electric field. However, the allowable deformation of dielectric elastomer actuators is severely limited by the material failures. To extend the actuation range, this letter investigates a network of two interconnected dielectric elastomer balloon actuators, each prestretched by ...

Stress measurements of planar dielectric elastomer actuators
Review of Scientific Instruments, 2016Dielectric elastomer actuator (DEA) micro- and nano-structures are referred to artificial muscles because of their specific continuous power and adequate time response. The bending measurement of an asymmetric, planar DEA is described. The asymmetric cantilevers consist of 1 or 5 μm-thin DEAs deposited on polyethylene naphthalate (PEN) substrates 16 ...

Polychloroprene: a new material for Dielectric Elastomer Actuators.
MRS Proceedings, 2011ABSTRACTDielectric Elastomer Actuators (DEAs) consist of an elastomeric layer sandwiched between two compliant electrodes. An electric field applied between the two electrodes will lead to a compression of the elastomer due to the Maxwell’s pressure. DEA can be used for many active applications such as pumps, muscles and so on, where the voltage drives
