- Dielectric elastomer actuators can be used to make soft and flexible grippers. This video shows a prototype of a 4-arms gripper.

could you make thousands of them in the form of threads to imitate muscle fibers ?
Can u plz tell me u have stretch in unidirection or bidirectional
would you please tell me
what kind of materials were used in test？
Have u any idea of elastosil silicon filn
Where can i get plz response if any body has knowledge
How u have fabricated it
Hi. Is there any chance you could give more information on how this works?
Information such as, are the wires connected or unconnected? what are the black rectangles? how are they contained on/within the surrounding material?
You can access a postprint of the article with all the details on this actuator here: infoscience.epfl.ch/record/200277?ln=en
you call 3,000 volts a minimum energy ? Who is going to have a battery holding 3,000 volts? Unless it is for a nuclear submarine. Not very practical for hobbyst robot builders.
Low amperage and low overall power with a high voltage isnt too difficult to achieve
Minimum energy structures is the name given to these mechanical structures with preloaded tensile stress, which take a resting configuration that minimises the mechanical energy in the structure. So the name is not related to the electrical energy required for actuation. This being said this is an electrostatic actuator, and therefore it doesn't require power to hold a static position. We use high voltage DC/DC converters to generate the high voltage, and they use a 5V input, compatible with batteries. As a matter of fact, our flying MAV used the same kind of actuators powered by a battery. See: ruclips.net/video/wjEJZ4e_YU4/видео.html
Except that hobbyists should've known about voltage multipliers
Volts, not amps
ever heard of a transformer?
