EcoPad Tablet Can Charge the Battery From Touch of Hand

Every time you touch the tablet actually you spend a little energy ... and so do you expend energy tablet that makes the battery slowly discharged. But designers Yonggu Do and Eunha Seo has a vision to create a tablet with a built-in piezoelectric film that could actually generate power every time you touch the screen. So you can go take the tablet without having to carry a charge.
EcoPad concept drawings depict a tablet that does not need to be charged at all, but we'll believe it when we truly see physical things. Because, when you watch the video, reading books or doing other activities on the tablet that does not require you to touch the screen.
On the other hand, tablets which utilize such technology could at least extend the life of your battery under certain conditions.
