Double-sided transparent touchscreen shown off on NTT DoCoMo prototype

See-through displays may or may not be making a comeback, but NTT DoCoMo is at least trying to give them a different spin. Working with Fujitsu, it’s added a Vita-style extra touch panel to the rear of the screen, which works with the transparency to let the user navigate Android without ever obscuring the UI with their fingers. It also allows new types of interaction based on “gripping” objects — holding down a finger at the back to modify the effect of a swipe on the front. The prototype was actually announced a little while back, but DigInfo has a video (embedded after the break) that shows how it works in practice — just don’t expect to be enjoying Netflix on that washed-out QVGA display anytime soon.

From Engadget: Copper-nickel nanowires from Duke University could make ubiquitous printable circuits

Nanowires

Nanowires, although they’re building steam, still have to overcome the not-so-small problem of cost — they often have to use indium tin oxide that’s not just expensive, but fragile. Duke University has developed copper-nanowire films that could remedy this in style. The choice of material is both a hundred times less expensive to make than indium and is much more durable. It’s flexible, too: if layered on as a coating, the nanowires would make for considerably more viable wearable electronics that won’t snap under heavy stress. The catch, as you might suspect, stems from the copper itself, which doesn’t conduct as much electricity as indium. The nickel will keep your copper electronics from oxidizing faster than the Statue of Liberty, however. Any practical use could be years away, but further successes from Duke could quickly see printable electronics hit the mainstream power and power our dreams of flexible displays.
