Nokia Working on Charge-less Mobile Phone

In order to attain charger less world, Nokia is working on a mobile phone that would be charged wirelessly through ambient radio signals that are available in atmosphere. Markku Rouvala, a researcher from the Nokia Research Centre, in Cambridge, U.K told MIT’s Technology Review that ambient electromagnetic radiation – emitted from Wi-Fi transmitters, cell-phone antennas, TV masts, and other sources – could be converted into enough electrical current to keep a battery topped up

The team at Cambridge is working on a prototype device that could harvest up to 50 milliwatts of power from the electromagnetic soup – which is sufficient to trickle charge a switched off phone.

Current versions can scavenge 3 to 5 milliwatts. To increase the amount of power that can be harvested, Nokia is focusing on harvesting many different frequencies. “It needs a wideband receiver,” says Rouvala, to capture signals from between 500 megahertz and 10 gigahertz–a range that encompasses many different radio communication signals.”

MIT noted that historically, energy-harvesting technologies have only been found in niche markets, powering wireless sensors and RFID tags in particular. If Nokia’s claims stand up, then it could push energy harvesting into mainstream consumer devices.

Rouvala said that he envisaged commercial products could be launched in three to four years time.

    very nice idea. the cell phones would be now more user friendly. hoping this technology would be implemented in a very short duration.

  • I hope it happens soon. I just hate to charge the battery 100 times a day.

    great…

    mera pass pehly say he asa mobiles hay jo charge nahi karna perta agar kese ko chaiya hay tu is no per contact kary 03228607100.starting price 10,000
    to 20,000.agar kese kay pass 3g tecnologe wala mobile ho tu us kay leya 3500 ruppes day kar app apna mobile ko recharge karanay ke janjat say azad ho saktay hay.

    Already been done by Nicola Tesla, 80 years ago…

      I would agree with Harrold here…..
