Nanotechnology is defined as the creation and manipulation of matter at a subatomic scale. And if you still think this is science fiction let me refer you to two articles that prove otherwise...
This first article is from a paper published back in August of 2012 which I found at IOPScience. In it the authors discuss using "semiconductor nanomaterials, advanced fabrication
methods and unusual device designs" (hmm, I wonder what unusual device designs are?) to create ridiculously thin "elastomeric
sheets" which could be used like gloves. "This type
of technology could be used in applications ranging from human–machine
interfaces to 'instrumented' surgical gloves."
The second article is from the November 2012 issue of Scientific American (a magazine which I highly recommend, btw) and discusses using nanotechnology to create artificial muscle. Apparently Ray Baughman (the director of the University of Texas at Dallas' Alan G. MacDiarmid NanoTech Institute) and his team have been able to use nanotechnology to spin "lengths of carbon nanotubes
into buff yarns whose twisting and untwisting mimicked natural muscles
found in an elephant's trunk or a squid's tentacles." More recently the team has reported advances that "makes their carbon nanotube yarns several times faster and more
powerful. These qualities could help deliver on the technology's promise
of developing compact, lightweight actuators for robots" and could enable "the artificial muscles
to lift more than 100,000 times their own weight and generate 85 times
more mechanical power ..."
MULHALL: Thank you. Have you prepared the negaton hydracoils for the drawing Sargon supplied?
For all the good it'll do you. It's a fancy name, but how will
something that looks like a drop of jelly make this thing work? You'll
need microgears and a pulley that does what a muscle does.
MULHALL: That would be highly inefficient.
SCOTT: I tell you, lady, this thing won't work.
It will have twice the strength and agility of your body, engineer, and
will last a thousand years. That is, assuming you'll stop wasting your
time and allow us to complete it.
