Miniaturized Dielectric Elastomer Actuators | EPFL-LMTS. DEA projects at the EPFL-LMTS Dielectric Elastomer Actuators (DEA) and Sensors In contrast to actuators based on rigid materials such as silicon, actuators based on elastomers can have very large percentage displacements, often exceeding 100% elongation, enabling new possibilities in many fields including soft robotics, tunable optics, and cell manipulation. We develop µm- to cm- scale Dielectric Elastomer Actuators (DEA) and Transducers for a wide range of applications.

The DEA principle of operation is illustrated on the right: a compressive electrostatic force is generated when a voltage is applied between the electrodes placed on both sides of an elastomer membrane, squeezing the membrane, which expands in plane.

Increasingly, there are efforts to reduce their size, mass, and power as well as use them to operate biologically inspired devices. Electroactive ceramic actuators (for example, piezoelectric and electrostrictive) are effective, compact actuation materials and they are used to replace electromagnetic motors. However, while these materials are capable of delivering large forces, they produce a relatively small displacement on the order of magnitude of fraction of a percent. History and currently available mechanical active polymers EAP characterization Summary. Electroactive polymers. (a) Cartoon drawing of an EAP gripping device. (b) A voltage is applied and the EAP fingers deform in order to surround the ball. (c) When the voltage is removed the EAP fingers return to their original shape and grip the ball. Electroactive polymers, or EAPs, are polymers that exhibit a change in size or shape when stimulated by an electric field.

The most common applications of this type of material are in actuators and sensors. History[edit] The field of EAPs emerged back in 1880, when Wilhelm Röntgen designed an experiment in which he tested the effect of an electrical current on the mechanical properties of a rubber band.[2] The rubber band was fixed at one end and was attached to a mass at the other. Polymers that respond to environmental conditions other than an applied electrical current have also been a large part of this area of study. The next major breakthrough in EAPs took place in the late 1960s.
