Dielectric Elastomers in Actuator Technology
Advanced Engineering Materials, 2005AbstractElectroactive polymers (EAPs) are characterized by their ability to respond to external electric stimulation by displaying a significant shape or size displacement. Actuators, based on dielectric elastomers exhibiting low elastic stiffness and high dielectric constants, can produce high strain levels from 10 to 380 %.

Applications of dielectric elastomer actuators
SPIE Proceedings, 2001Dielectric elastomer actuators, based on the field-induced deformation of elastomeric polymers with compliant electrodes, can produce a large strain response, combined with a fast response time and high electromechanical efficiency. This unique performance, combined with other factors such as low cost, suggests many potential applications, a wide range

Actuated Micro-optical Submount Using a Dielectric Elastomer Actuator
IEEE/ASME Transactions on Mechatronics, 2011Analysis of the operating characteristics of a dielectric elastomer actuator (DEA) submount for the high-precision positioning of optical components in one dimension is presented. Precise alignment of a single-mode fiber is demonstrated and variation of the sensitivity of the submount motion by changing the bias voltage is confirmed.

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 ...

Integrated sensing and actuation of dielectric elastomer actuator
SPIE Proceedings, 2017Dielectric elastomer (DE) is a type of soft actuating material, the shape of which can be changed under electrical voltage stimuli. DE materials have great potential in applications involving energy harvesters, micro-manipulators, and adaptive optics. In this paper, a stripe DE actuator with integrated sensing and actuation is designed and fabricated ...

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
