[SciDaily]Graphene Crumpling Forms Artificial Muscle

post #1 of 11

In addition, the Duke engineers layered the graphene with different polymer films to make a "soft" material that can act like muscle tissues by contracting and expanding on demand. When electricity is applied to the graphene, the artificial muscle expands in area; when the electricity is cut off, it relaxes. Varying the voltage controls the degree of contraction and relaxation, giving actuation strains over 100 percent.

"Indeed, the crumpling and unfolding of graphene allows large deformation of the artificial muscle." Zang said.

"New artificial muscles are enabling diverse technologies ranging from robotics and drug delivery to energy harvesting and storage," Zhao said. "In particular, they promise to greatly improve the quality of life for millions of disabled people by providing affordable devices such as lightweight prostheses and full-page Braille displays. The broad impact of new artificial muscles is potentially analogous to the impact of piezoelectric materials on the global society."

Keep it up, theres got to be more ways to use this wonderful Graphene!

Thought I would share this, I always like reading about the odd things that can be done with Graphene

While the article does not expand on the details of the Muscle contractions and strength. We have to look at the components. Even on the surface I cannot imagine this technology developing into something weaker than animal muscle per se'.

http://en.wikipedia.org/wiki/Graphene
Quote:
Graphene is a substance composed of pure carbon, with atoms arranged in a regular hexagonal pattern similar to graphite, but in a one-atom thick sheet. It is very light, with a 1 square meter sheet weighing only 0.77 milligrams...

Graphene is most easily visualized as an atomic-scale chicken wire made of carbon atoms and their bonds. The crystalline or "flake" form of graphite consists of many graphene sheets stacked together.

I hope this technology moves fast so we can see the benefits. It's one of those fundamental technologies that if harnessed correctly could change and create entire new industries. Yes like a Nanosuit, which if backing from the "War Machine" arrives, then who knows what they can create. Robotics could explode on several levels.

robotics wouldnt need to rely on hydraulics/pneumatics in order to move arms and legs, instead they could have the finesse that animals and humans have, which is why I think this will be great for prostetics specifically.
