Human Motion Powered Nanotechnology Devices
Michigan State University researchers have came up with a new method for harvesting energy from human motion using nanotechnology. They designed a low-cost film-like device, a nanogenerator, than can power a LCD display, keyboard, and some LEDs without any source of electric power, by...
