The dielectric elastomeric actuators are an emerging class of polymer actuators. These polymers can execute large strains at high voltages. They basic variation among different actuators is in their geometry. Currently different geometries are being investigated for better efficiency, displacement, and force requirements. Due to their fully polymer construction it has the advantage of being safe from magnetic fields, and due to its simple operation methodology controlling electronic requirements can be reduced. This makes it suitable for the use in MRI (Magnetic resonance Imaging) environments. As it is extremely cheap it can be made disposable and help in reducing cross infections and improve sterility. The actuators of this kind can be used for applications extremely specific for medical device industry like positioning of devices. So there is a requirement of having these types of actuators in the medical device domain and need to be addressed

Introduction The landmark papers by Pelrine et al. marked the beginning of the use of dielectric elastomer (DE) actuators (and sensors) for soft robotics.[1] They showed that a voltage applied through the thickness of a soft material could produce large strains as a result of the Maxwell stress between charges on the two electrodes.

Dielectric elastomers - Wikipedia ~ Dielectric elastomer actuators are to be designed so as to avoid the phenomenon of dielectric breakdown in their whole course of motion. In addition to the dielectric breakdown, DEAs are susceptible to another failure mode, referred to as the electromechanical instability, which arises due to nonlinear interaction between the electrostatic and the mechanical restoring forces. In several cases .
