Flexible PaperPhone wants to get bent out of shape (video)
We love our smartphones (in part) because they're flexible, in the sense that they are mighty multitasking machines. Researchers from Queen's University in Ontario Canada, however, want flexible phones in a literal sense -- less five-tool player, and more master contortionist. Using a ductile e-ink display and elastic electronic underpinnings, they created a device called the PaperPhone that literally bends to its user's will. Curling the corners of the device isn't just for show, either, as folding the phone is how users navigate menus and make calls. We aren't completely sold on the idea of a bend-based UI, but we're definitely digging the lithe and lightweight phone form factor. Video of the new flexi-phone is after the break. Update: A second video showing the same 3.7-inch display in a wearable computer project dubbed, "snaplet," has been added after the break.
Researchers develop scalable circuit printing technique
As if there weren't enough "almost theres" in the world of printable circuits, now we've got yet another team developing their own iteration of a printing press for electronics. The group, which includes scientists from DuPont and Organic ID, has reportedly "fabricated a printing plate used to print the source-drain level of an array of thin-film transistors," essentially solving some of the low-resolution constraints seen on prior competition. The goal is to eventually posses the ability to "print large, flexible circuits using machines similar to printing presses," and while it seems to be a ways from commercialization, initial testing and comparisons to more traditionally-created transistors have produced glowing results.[Image courtesy of HowStuffWorks]
HP's advancements in adaptable circuits could keep Moore's Law alive
Though we're guessing ink-jet cartridges are foremost on its mind, HP's new flexible circuits could make adaptable microchips possible at the consumer level, opening up whole new worlds of computer use and weird new hacker exploitations. Just like everything else new and hip these days, the new chips involve a few "nano" buzzwords, but instead of going for a full-on molecular computer like many current researchers are doing, HP is taking a bit of a hybrid approach. The new HP design uses a traditional silicon-based chip, with a mesh of nanowire switches on top. The nanowires provide flexibility to the chip, allowing it to adapt to tasks or be upgraded to a new wireless spec, but the silicon still does all the heavy lifting. Plus, the molecular switches don't draw any power except when switching from one state to another, so overall power consumption is reduced. The design is pretty much finished, so right now the HP researchers are building the first prototype, and should be finished by the end of the year. As far off as that may seem -- and there's no telling how long it will take to commercialize this once the prototype is finished -- it sounds like these guys are well ahead of other molecular computing projects, and should provide a nice stopgap for expanding computer performance while we wait for full-on molecular processors to start bumping our FPS frame rates.
