Materials scientists are developing an eye-shaped camera that uses a single lens to produce a distortion-free image. Most cameras require multiple lenses but the human eye does not. Now though, John Rogers and his colleagues at the University of Illinois at Urbana-Champaign used flexible electronic circuits to mimic our own single-lens eyes. From Nature News:
The team's solution was to use a series of silicon photodetectors (pixels) connected by thin metal wires. This network is supported and encapsulated by a thin film of polyimide plastic, allowing the flexible scaffold to bend when compressed. This scaffold takes up the mechanical stress and protects the pixels as the array takes its hemispherical shape.

The team made a hollow dome about 2 centimetres wide from a rubber-like material called poly(dimethylsiloxane). They flattened out the stretchy dome, and attached the electronic mesh. Then, as the hollow dome snapped back into its original shape, it pulled the array with it, forming a hemisphere that could be attached to a lens; the basis of the camera
“The ability to wrap high quality silicon devices onto complex surfaces and biological tissues adds very interesting and powerful capabilities to electronic and optoelectronic device design,” says Rogers. "It allows us to put electronics in places where we couldn't before."
Neglected public payphones in New York City are being turned into “GuyFi” stations: a place where one can rub one out for the sake of “stress relief.” Annalee Newitz reports on the wank booths from a company named “Hot Octopus”… The company reported that at least 100 men used the booth on its opening day […]
You’d be forgiven for thinking the videocassette format long-dead, but it turns out that Betamax is still around. Sony is finally going to withdraw tapes from sale, bringing a 40-year story to an end. The last recorders were sold in 2002. ベータビデオカセットおよびマイクロMVカセットテープ出荷終了のお知らせ [Sony; via The Verge]
A leaked Comcast memo discloses that the company’s consumer data caps have nothing to do with network congestion, contrary to its public claims. The internet service provider has often complained (such as when lobbying against net neutrality) that it must impose limits on service to prevent network congestion. The argument suggests that these measures are […]
Plastic is so 2013. You don’t want to buy something only to throw it away or lose it and barely care. You like nice things and want to hang onto them. The Plazmatic lighter here is a high quality, high tech alternative to the typical cheap, plastic lighter you get at the old gas station. […]
Real engineers build things. Super cool engineers build things with their hands and fingers, like our engineering forefathers did. No idea where to even begin to do that? This step by step Arduino course is now 92% off and is going to get you up and running, from zero to hero, in no time. So […]
How do Google and YouTube really work? It turns out, Python kind of runs things around those parts. And with this bootcamp, you’ll get whipped into shape and ready to start programming yourself. Whether you’re a Python pro and just want to sharpen your skills, or a total tech newbie with little or no coding […]
