Scientists in America have developed a microfiber fabric that can generate electricity, apparently producing enough current to recharge a cell phone or ensure that a small MP3 music player never runs out of power.
If made into a shirt, the fabric could harness power from its wearer simply walking around or even from a slight breeze.
The generator takes advantage of the semiconductive properties of zinc oxide nanowires - There are tiny wires 1,000 times smaller than the width of a human hair embedded into the fabric. The wires are formed into pairs of microscopic brush-like structures, shaped like a baby-bottle brush. One of the fibers in each pair is coated with gold and serves as an electrode. As the bristles brush together through a person's body movement, the wires convert the mechanical motion into electricity and can produce up to 80 milliwatts per square meter of this fabric.
There is only one problem with this at the moment, zinc oxide degrades when wet. Im sure the scientists will be working on a solution to this problem.
