Does this mean there will come a day when I'll never have to recharge my mobile phone?

Maybe eventually, but remember the amount of power being harvested from the airwaves is very small. Not enough to run a display and cellular transmitter for an extended period. But it could enable your phone to broadcast its location a short distance if lost and out of power.

That would actually be a great feature. So many hours lost while searching for my misplaced, battery-dead phone.
