Elfin Aerial

September 1, 2004

A team at the University of Florida led by electrical engineer Kenneth O has built a tiny antenna that can send a radio signal across a room. Only three millimeters long and 100 micrometers wide, the antenna is the first of its size with so great a range – about five meters. The tiny antenna is an important step toward O’s goal of building an entire radio transceiver on a single microchip. The most likely applications for such radios, he says, are in cheap, robust sensor networks for security systems or for monitoring the safety of bridges or buildings; the radios would send data wirelessly from the sensors to a central monitoring computer. And one company has approached O about using the radios to make interactive toys. He hopes to have built prototypes of complete on-chip radios in about two years; in the meantime, his team is working to improve the antennas’ range to at least 20 meters.

Five poems about the mind

DREAM VENDING MACHINE I feed it coins and watch the spring coil back,the clunk of a vacuum-packed, foil-wrappeddream dropping into the tray. It dispenses all kinds of dreams—bad dreams, good dreams,short nightmares to stave off worse ones, recurring dreams with a teacake marshmallow center.Hardboiled caramel dreams to tuck in your cheek,a bag of orange dreams…

I taught myself to lucid dream. You can too.

We still don’t know much about the experience of being aware that you’re dreaming—but a few researchers think it could help us find out more about how the brain works.

Is everything in the world a little bit conscious?

The idea that consciousness is widespread is attractive to many for intellectual and, perhaps, also emotional
reasons. But can it be tested? Surprisingly, perhaps it can.
