Nokia has recently issued what could be a truly revolutional patent: a self-charging graphene-based photon battery, capable of being printed on flexible substrates.

The patent describes a battery that can regenerate itself immediately after discharge through continuous chemical reactions, without an external energy input. The result is an energy autonomous device. The battery uses humid air for the purpose of recharging and be made highly transparent.

Whether this patent will actually be used for the manufacturing of commercial devices remains to be seen, but if it does, it should be quite life-changing.

Last month, we wrote about Nokia possibly nearing prototype stage of their graphene-based optical sensors project.
