Tiny MP3 player looks like a Band-Aid and is powered by body heat

"Why is that Band-Aid making noise?", you may be asking. Actually, it's a tiny MP3 player designed by Chinese engineers that is powered by body heat.

The Skinny Player is flexible, has adhesive on one side and reusable. The battery charging strip is located on the under side of the device and uses heat from the human body to power up. Each Skinny Player holds one album's worth of music and would be great for using when you're working out.
