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 ?

Hi. Is there any chance you could give more information on how this works?

@BurchAnthony 8 жыл бұрын

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

How u have fabricated it

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: kzfaq.info/get/bejne/rdB1fb1lysW9hWg.html

Except that hobbyists should've known about voltage multipliers

Volts, not amps

ever heard of a transformer?
