iPods Charged by the Human Heart

The Apple iPod has been nipped and tucked since its original version to become the compact, nearly paper-thin music-playing masterpiece that it is today. We now have room for thousands of songs and videos on a piece of metal that's smaller than a playing card and lighter than a feather.

Just when we thought there was no more improving the little guys, technology went ahead and proved us wrong. Scientists from Georgia University of Technology, lead by Dr. Zhong Lin Wang, are in the experimental stages of developing nanotechnology that will create self-generated energy that could power portable devices like iPods. In presenting their findings to the American Chemical Society, Dr. Wang explained that the devices would have a microchip made of zinc oxide nanowires (500 of them could fit on a human hair) that generate energy at any body movement, even just the beat of a heart.

So far the human-powered technology has been used to power LCD screens and store radio signals. These advances may seem small, but Dr. Wang believes that the team's development of the microchip is a significant milestone in the creation of power that isn't battery-operated or plugged into an electrical outlet. "Their potential is only limited by one's imagination," he said. We're certainly looking forward to listening to beats powered by heartbeats.
