New Yarn Conducts Electricity
sciencehabit writes: Researchers report the creation of an ultrathin, fabric circuit that keeps high conductivity even while bending and stretching as much as yoga pants. The fiber's core mimics spandex, consisting of an elastic synthetic thread—polyurethane—twinned by two cotton yarns. These stretchy strings were then dipped in silver nanoparticles to instill conductivity and then liquid silicone to encase everything. This silver nanoyarn could stretch as much as spandex—500% of its original length—and retain a high conductivity (688 siemens per centimeter), the team reports online this month in ACS Nano. That's 34 times the conductivity and five times the flexibility seen with prior attempts at nanowires made from graphene. The fibers kept high conductivity after being bent 1000 times or wrapped around fingers. The team used their yarn to link light-emitting diodes within foldable plastic, meaning the fibers might serve as flexible wiring in new-age curved TVs, stretchable digital screens, or electronic clothing.
profit!
Do do do do do do do do do do, do do do do do do do do do ....
Finally there is a respectable replacement for the tin foil. Electricity conducting fabric can also act as a Faraday cage, thus tin foil can be retired.
The problem is that such electricity conducting clothes will drive magnetic scanners crazy in the airports, and we should expect the roll-out of TSA procedures to screen naked people, for such clothes will be impenetrable to the airport porn scanners.
So we really want silver embedded in our fabrics not copper, good to know.
The X-Men will come to fear the true source of my power...
I AM ELECROCHET!
Mod me down, my New Earth Global Warmingist friends!
yoga pants .. siemens per cm. insert joke here
This is just what we need to wear to taser-proof ourselves. The conductive fibres should be able to short out the high voltage more effectively than our bodies. We might get a little burned---I'm not sure how much power (as opposed to voltage) tasers put out---but I suspect that's going to be preferable to the alternative electrocuting effects. I guess if it works the police will ban it the same as bullet-proof vests.

instil
verb
1. gradually but firmly establish (an idea or attitude) in a person's mind.
2. put (a substance) into something in the form of liquid drops.
Which sense of instil did you mean?
I don't want to know how much semen you can get on your yoga pants, much less 600. Yuck.
Holy shit you guys, if you dip things in silver, they become conductive to electricity!
Yes they are. I remember having this idea when I worked for a Fashion Designer School back in my youth. I was an avid electronics hobbyist and already thought of sewing electronics into garment back then. You could make scrolling text, spectacular graphical displays, especially easy today with all the Arduino/AVR microcontrollers cheaply available just about anywhere.
Other ideas, the Customs officers could have metal detection technology built right into their garment/gloves etc. Other detectors too, the uses are unlimited.
What this world is coming to - is for you and me to decide.
We know about this new stuff, but for comparison we need to know how many semens per centimeter there can be on conventional yoga pants.
Old yarn conducts orchestras.
Are they really saying fat guys like me can be electrifying?
Having to work for a living is the root of all evil.
After an EMP attack, the phone in your pocket would still work. The bad news is that even if you could locate the eight or so other hipsters who might be wearing conductive pants, the communications infrastructure would still be fried.

Big apple, new Yorik, undig it, something's unrotting in Edenmark.
"500% of its original length"
Wait a minute; that's five times the original length. Are we supposed to be impressed by the big number? Well let's make it bigger: 500.000%
The summary begins with "Researchers report...", but this sounds like marketing exaggeration. Is there anything in the summary but useless numbers and facts followed by wild speculation?
...omphaloskepsis often...
Teletubbies tech!
That's a valid unit, sure, but... why?
You show this to anyone who works with electronics and the first thing they are going to do is ask that be turned into ohms/meter, just like any other form of wire. Siemens are a materials-scientist unit, not an electronics unit.
Combine this with flexible batteries (or at least very high-energy ones, and we have clothes which can heat themselves! Imagine a sock or vest which can keep you warm for a number of hours if need be.
Why OpalCalc is the best Windows calc
A new way to make headphones and earbuds and everything else even more flaky and more non-repairable. I replaced the horse-hair wire of my daughter's headphones with double-ought wire. She doesn't use them anymore... but they still work!
<blink>down the rabbit hole</blink>
Finally comfortable electric chair!

My doctor says that's low.
It reminds me an old Dilbert strip, http://dilbert.com/strip/1999-12-26.
Cool! Every rime I take a dump I'll think of you!
I got to the chocolate box before you, that's why the hard ones have teeth marks.
If conductivity is the recripocal of resistivity, then shouldn't the number of siemens, i.e. the magnitude of conductivity decrease with length? If so, how does it make sense to refer to siemens per meter?
