New Connections For Stretchable, Twistable Electronics
tugfoigel writes "Jizhou Song, a professor in the University of Miami College of Engineering and his collaborators Professor John Rogers, at the University of Illinois and Professor Yonggang Huang, at Northwestern University have developed a new design for stretchable electronics that can be wrapped around complex shapes, without a reduction in electronic function. The new mechanical design strategy is based on semiconductor nanomaterials that can offer high stretchability (e.g., 140%) and large twistability such as corkscrew twists with tight pitch (e.g., 90 degrees in 1 cm). Potential uses for the new design include electronic devices for eye cameras, smart surgical gloves, body parts, airplane wings, back planes for liquid crystal displays and biomedical devices."

The black man's skin is thick and lush, sensuous to the touch, like satin and velvet made flesh. There's only one patch of skin on a white man's body that remotely compares to nearly every inch of a black man's skin.
And I had the socially acceptable explanation for my craving. I used that paucity-of-available-white-partners rationale to explain my relationships with black men for several years. A white woman past forty is often passed over by her white-male contemporaries. Black men are happy to get the babe they couldn't have when she was twentysomething and fertile.
I want black men. They want me. The white woman who goes after black men is a variant of sex journalist Susie Bright's "white bitch in heat," a woman who puts sex first even though women aren't supposed to do that. According to one school of thought, white women turn to black men when their sex drives kick into higher gear and their social inhibitions recede into the rearview mirror. It's a "yes, baby, now I'm ready for you" reaction.
Black men have something white guys don't have anymore: confidence in their masculinity, their sexuality. They clearly know they're men. White men appear to be waiting for the latest sociological research study to let them know if they are men or not. Yet black men are gentlemen, something else white men no longer are. They make me feel like a woman, both respected and desired. I can let go of my inhibitions, my need to control, when I am with them. How many white men can treat a woman like a lady and ravish her too? The last time I had sex with a white man, we slogged along a bumpy road in a really old VW, the driver like the typical bumbling tv husband who would neither ask for nor accept the directions he badly needed.
My current lover, a handsome businessman, seduced me via eye contact at a neighborhood buffet while I was eating fatback and chicken wings with a friend. Without saying a word, he paid the compliments, asked the questions with his expressive eyes. He didn't move over to sit beside me and ask if he could buy me a drink until he knew the time was right. Both soft-spoken and assertive, he has impeccable manners and charm. I was kissing him in a cab 30 minutes after that drink.
Black penises look better than those of white men, and black men touch and kiss and make love better than white men. Statistically, their penises are only a fraction of an inch bigger on average, but they seem bigger and harder. White men over 40 have lost their waistlines and their zest for life if they ever had it. They carry resentments, grudges and extra pounds in their basketball bellies. Perhaps a good part of that bloat is unhappiness. Even the thin ones look flabby somehow and deeply aggrieved. They nurse the smallest perceived slight longer than their double shots of Scotch. Surely our culture as much as biology turns them into softer, spongier, less-interesting versions of their youthful selves just at the point where women and black men and other minorities are emerging strong. Society overvalues the white man, leaving him angry and bitter when he realizes, around age 40, that he's not all that.
Halfway through the first glass of wine in my last date with a white man, I realized that little clouds of sadness and self-pity were regularly fluffing off his psyche like the dust clouds kicked up by that dirt-smudged "Peanuts" character as he walks through Charlie Brown's life. This guy was at least mildly depressed, and I wanted to tell him to exercise, lose weight, trim the combover and get interested in something outside himself. I would have walked out on him immediately, but he seemed to expect that. I couldn't deliver the blow to his ego proffered like the naked neck of a martyr to the ax. My Southern cousins would describe his general demeanor as a "hangdog air." Into the second glass of wine and glancing longingly at the exit, I wanted to hang that dog myself when he mentioned that his face was flushed. I hadn't noticedbecause he'd taken a Viagra "just in case."
Does this make it less likely that my headphone wires won't automatically seek to form the most complex DNA strands in the universe?

Screw body parts. Tentacles baby!
How many of these have come out in the past month? it seems like were being flooded with flexible chips and displays and electronics. at this point i don't care. all i want is an mp3 player thats as thin as a credit card and i can role up.
O.o
>> ... body parts,
Not sure 140% will be enough but its a good start.

Shouldn't this be used for every type of cables? During the last couple of weeks, coiled USB cables have given me lots of grief. USB connected camera stands (used for passport pictures) keep being disconnected, but as soon as the cable has been straightened (5 meters), everything's fine.
Recently I had the same problem with a Cat5e cable at some other place; 5 meters, half of that from the IP phone to the wall; as soon as I straightened it up, the phone was able to connect.

I thought one of the deals holding up the big wheel spinning in space for artificial gravity - like the station in 2001 A Space Odyssey was connections between the core and the spinning part. Maybe somehow this will help.

Oddly enough, I was watching Spiderman 2 at the dentist's office today and thinking, "What I wouldn't give for the stretchable electronics and semiconductor nanomaterials that would allow me to have sweet electromechanical appendages like Dr. Octopus..." And then I go on Slashdot a few hours later, and find that my dream will soon be a reality!
...a character has a pocket-sized screen that he enlarges by _stretching_ it. I think of this when browsing the Web on a mobile, especially iPhone-like devices with their stretching fingers-metaphor.
Rolled up circuitry will allow for very dense electronics, which may turn out to be more practical than 3d-chips and other such advances. I've often wondered about finding a way to fold semi-conductors up like origami. If we are ever to have a nanotech revolution with smart machines tiny enough to float around our blood stream and other such applications for nanomachines, it's going to be necessary to package alot of processing power in to a small volume.
Consider that it is somewhat easier to print your circuitry in two dimensions, then to fold it up very small.
This is also helpful for making of smart materials, for example it'd be no use having a smart skin for a aircraft if fatigue and deformation destroys the circuitry within it.
After logging in slashdot still does not take you back to the page you were on. It's been that way for 20 years.
I thought Bill was looking rather pathetic lately. It's all so clear now.
The length of a wire is limited by the wavelength of the signal it must pass. The rule of thumb is that any conductor longer than 1% of that wavelength must be treated as a transmission line. A transmission line depends on its physical properties. If any of those properties changes then the characteristic impedance of the cable changes. When that happens, signals no longer pass as they should, they distort and reflect and generally provide misery.
With the above in mind, my WAG is that the clock rate of stretchable electronics will be limited to the low MHz.
I hope it prevents cell phones from breaking when dropped. Think of the effect that will have on landfills! Currently if you drop your cell phone, chances are some connection comes loose. Then the phone shuts down or malfunctions intermittently. What we need are electronic connections that don't break when a shock is received.
fits all...now goes electronic!

I know this is extremely grammar nazi-ish, but the article uses "e.g" where "i.e." is more appropriate. "e.g" stands for the Latin "exempli gratia", meaning "for example. "i.e.", on the other hand, stands for "id est", meaning "that is". Because the article gives the specific maximum values for stretchability and corkscrewing, rather than examples from a range of values, "i.e." should be used.
Blend this with the flexible display technology and you'll have something I'll be willing to have embedded subcutaneously. (But please don't add any 'enhancements' like GPS, ID verification, or anything which would allow the government to monitor my whereabouts.)
If your only tool is a hammer, every problem becomes a nail.
Take a flexible OLED, back it with this flexible circuitry, add a flexible battery and you've got an electronic material which could really give paper a run for it's money. Is there flexible memory or storage yet?

What cell phone do you use? I have a cheap Nokia GSM phone - it's got a black & white screen,
no camera, no radio, no music player.
It's 2 years old - fallen on hard ground multiple times.
It's even fallen into a bucket of water ones.
It's working fine. Doesn't shutdown or malfunction.
