Buckeyes embed antennas in clothes, couture to improve radio reception?
We like what's in our wardrobe to be multifunctional, and we've seen threads do double duty as keyboards, flashlights and even drum kits in our day. Now, researchers at Ohio State have come up with a way to turn the shirt on your back into an omnidirectional antenna to boost radio reception. To do so, they etched brass wires into plastic film to create flexible antennae, and stitched 4 of them into the shoulders, chest and back of a vest. Using a computer controller the size of a deck of cards clipped to the wearers belt, the system senses body movement and activates the appropriate antenna to get the best signal. You see, antennae don't work so well when touching human skin -- as any iPhone 4 owner can attest -- and the multiple antenna system alleviates that problem while providing "significantly greater signal strength" than a standard antenna. The researchers see the technology having great appeal for the military, law enforcement, and emergency personnel, but here's hoping they make a consumer version, too. It'd be nice to eliminate all those cell-service dead spots by simply donning a jacket, right?
NEC develops Wideband Wearable Antenna
TV's important right? Sure, now ask yourself: Is it important enough to turn your meat sack into a wideband antenna? NEC thinks so and just announced (officially, that is) its wideband wearable antenna which turns a small, flexible print substrate into a high-performance mobile antenna. The prototype is said to work equally well in open space or when operated up against the juicy impedance of the human body. NEC will be testing the first prototypes for reception of digital terrestrial broadcasts in the 470-770MHz band -- perfect for that upcoming FCC auction eh, cowboy?[Via Akihabara News]
