Technology is everywhere today and it's only a matter of time before an even more user-friendly aspect of many of these devices becomes self-powered. What would make this possible is via touch-responsive nano-generator films that could powered touch screens. The same screens that are found in smart phones, laptops and tablet computers. When a screen flexes under a user's touch this is what will activate the electrical energy needed.
It's still about five years from the market and as stated in the article, "The field is young, and some major challenges remain. The power output of a single piezoelectric nanowire is quite small (around a picowatt), so harvesting significant power requires integrating many wires into a large array; materials scientists are still experimenting with how to engineer these screens to make larger devices."
It's great to know that one day we won't have to reply on power outlets or batteries to recharge our tech devices that will instead be continually charged as we use them.
