Body Heat-Powered Audio Player

Even as iPods get smaller and smaller by the month, it seems, this one is no thicker than the average Band-Aid. The Skinny Player, designed by Chinese engineers Chih-Wei Wang and Shou-His Fu, sticks to your skin and is powered by your body's own heat, eliminating the need for any clunky clips, arm bands, or other unnecessary gear. The downside, though, is that because of its slim profile, it has no touch screen or buttons, nor can you plug headphones into it anywhere, so you have to listen via an extra set of sticky speakers. Right now, the Skinny Player is just a concept, but certainly is interesting in its gadgetry and use of an untapped renewable resource!
