Self charging devices have been dreamt about for a long time now, and there have been many attempts to come up with a good implementation of such a concept. Now Nokia has managed to lay claims to a patent that could result in a self charging mobile phone (or gadget). According to the patent, the design will see the heavier components inside the phone supported on a sturdy frame, the frame will be able to move along two sets of rails, allowing it to travel up and down from one side to the other. With strips of piezoelectric crystals at each end, a current will be generated when the crystals are compressed, charging a capacitor which can trickle charge the battery, giving it a little more juice while you walk to the grocery store.
