Every time you touch a tablet you’re expending a little bit of energy… and so is your tablet as its battery slowly drains. But designers Yonggu Do and Eunha Seo have a vision for a tablet with a built-in piezoelectric film that could actually generate power every time you touch the screen so that you could go longer without having to plug in the tablet.
The EcoPad concept images depict a tablet that never needs to be plugged in at all, but I’ll believe that when I actually see it. After all, how would you watch a video or read a book or perform other activities which don’t require you to touch the screen very often?
On the other hand, a tablet that harnesses this kind of technology to at least prolong your battery life under some circumstances would certainly be pretty cool.
