For decades both material scientists and engineers have sought to find an artificial equivalent of muscle to help in the development of new transducer technology. A specific class of electroactive polymers (EAP) known as `dielectric elastomers' have demonstrated most potential because they can undergo large deformation, have a high energy density and a relatively fast response. This contribution introduces...
Dielectric Elastomer is considered as a kind of promising biomimetic actuator material which behaves similar to human muscle and can produce significantly large strain at high pre-stretch. It generated considerable interests in recent years for use in robotics and mechatronic applications. This paper is mainly on fundamental planar actuation experiment from which we abstract some Voltage-Area deformation...
Dielectric elastomer actuators (DEAs) are promising for bionic and robotic applications. Reliability requirements in such applications necessitate better knowledge of the safe operation regimes and possible failure modes of DEAs. Elastomers consist of a network of entangled and cross-linked polymer chains, able to sustain spatially varying stress and strain fields, accompanied by stored elastic energy...
