Tired of having to carry batteries around with you for all your devices? Scientists at the Georgia Institute of Technology are looking to change all of that by using nanotechnology to turn you into a battery. Zinc oxide nanowires, which are non-toxic and safe for humans, would be implanted into the body. The bending and relaxing of those wires would create electricity. That means that we would be creating electricity just by moving or flexing our muscles. These nanowires are so small they would not impede or constrain people. A nanometer is just one billionth of a meter. A human hair is about 100,000 nanometers thick.
