متن کاملDielectric elastomer cylindrical actuators: electromechanical modelling and experimental evaluation
This paper presents an experimentally validated electromechanical model of cylindrical actuators made of dielectric elastomers with compliant electrodes. Modelling was based on independent electrical and mechanical analyses of the specific configuration of the device. The expressions of the electrostatic pressures exerted by the electrodes in response to an applied voltage were formulated and i...
متن کاملA method to analyze electromechanical stability of dielectric elastomer actuators
This letter describes a method to analyze electromechanical stability of dielectric elastomer actuators. We write the free energy of an actuator using stretches and nominal electric displacement as generalized coordinates, and pre-stresses and voltage as control parameters. When the Hessian of the free-energy function ceases to be positive-definite, the actuator thins down drastically, often re...
متن کاملHelical dielectric elastomer actuators
This paper presents a new type of contractile polymer-based electromechanical linear actuator. The device belongs to the class of dielectric elastomer actuators, which are typically capable of undergoing large deformations induced by an applied electric field. It is based on a novel helical configuration, suitable for the generation of electrically driven axial contractions and radial expansion...
متن کاملOn designing dielectric elastomer actuators
Subject to a voltage, a dielectric elastomer can deform substantially, making it a desirable material for actuators. Designing such an actuator, however, has been challenging due to nonlinear equations of state, as well as multiple modes of failure, parameters of design, and measures of performance. This paper explores these issues, using a spring-roll actuator as an example. We formulate the e...
