Cal researchers create ‘energy-scavenging nanofibers,’ look to energize your next A&F sweater
We’ve seen the magic of piezoelectrics before, but if a team of Cal Bears can really deliver, their spin on things will actually make a difference in the retail realm. Engineers at the University of California, Berkeley have concocted so-called “energy-scavenging nanofibers,” which could one day be “woven into clothing and textiles” in order to convert into electricity the energy created through mechanical stress, stretches and twists. If everything works out, these movement-lovin’ clothes could theoretically power your phone and / or PMP as you walk, and for those concerned with cost, we’re told that the organic polyvinylidene fluoride materials use to make the nanofibers are easy and cheap to manufacture. Too bad there’s no direct confirmation that PVDFs are machine washable, but hey, that’s why you’ve got the local dry cleaners on speed dial.

NC State intellects design twistable, shape-shifting antennas
NC State may be well on its way to yet another underwhelming season on the hardwood, but it seems as if a few of its most spirited boffins aren’t even taking any time off to celebrate the season-ending victory over the hated Heels on the team’s final football game. Dr. Michael Dickey and team have just published their latest invention, and if this thing ever reaches commercial status, you can expect ordinary objects to become a lot more intelligent. The crew’s shape-shifting, twistable antenna overcomes the common limitation of copper-based alternatives by relying on an alloy that can be “bent, stretched, cut and twisted” while still transmitting or receiving a signal. Aside from enabling concept phones like the Ondo to become real, the development could also allow for stretchable antennas to be integrated into actual structures, giving buildings and bridges a way to communicate stresses to architects. Too bad it can’t communicate the crumbling of an athletics program to an oblivious AD, but hey, there’s always room for improvement in version 2.0.

Blinking LEDs to give QR codes a run for their (ad) money
We’re still waiting for this so-called QR code revolution to hit North America, but our contemporaries across the Pacific are already looking to develop the next big thing. Reportedly, a smattering of mega-corps (including the likes of Toshiba and NEC) are joining hands in order to concoct a rivaling technology that requires even less effort to get content from billboards, books and posters to one’s mobile. The heretofore unnamed system utilizes blinking LEDs to send data to phones, and so long as an ad has enough room for a minuscule light, consumers can come within five meters of it and receive the associated information by simply pointing their handset in the direction of the light. If all goes well, the technology will be ready for commercialization by 2013, or just after phase one of the Robot Apocalypse.
