The designers of the Ecopad mention that this concept generates electricity thanks to the touches on its touch screen. They say that a nano-piezoelectricity film would capture a tiny bit of energy whenever a user presses the screen with their fingertips. It sounds like a cool idea, but I have trouble imagining how practical this would be for generating enough power to operate a tablet.
The Ecopad concept was given a special award in Fujitsu and designboom’s ‘A Life with Future Computing‘ design competition for its innovative approach to juicing up.
