Nanogenerators produce electricity by squeezing your fingers together, while you dance

It's been a while since we last heard about nanogenerators - you know, those insanely tiny fibers that could potentially be woven into your hoodie to juice up your smartphone. Dr. Zhong Lin Wang of the Georgia Institute of Technology has reported that he and his team of Einsteins constructed nanogenerators with enough energy to potentially power LCDs, LEDs and laser diodes by moving your various limbs. These micro-powerhouses - 1x500 the width of a single hair strand - are embedded with piezoelectric zinc oxide atoms and can generate electrical charges when flexed or strained.
