Nokia is developing a technology that will break into the world of cell phones. A cellphone that no longer needs a charger because the battery can charge itself.
The Nokia Research Center in Cambridge, England has developed a prototype cell phone that uses radio waves or electromagnetic radiation as a power source. The radio waves in question are those emitted by devices such as WiFi transmitters or other telecommunication antennas.
Later, the Finnish company hopes that its mobile phones can charge it independently by only relying on energy sources in the air.
The technology in this cellphone can convert electromagnetic waves into electrical signals to power the cellphone. Nokia Research believes, it only takes 3 to 5 more years before this technology is perfect and can be marketed to the public.
Indeed, at this time, the Nokia prototype phone has not reached the target of collecting around 50 milliwatts of power for the minimum recharge requirement. Currently, the new Nokia prototype is able to collect 3-5 milliwatts of electricity. However, Nokia is optimistic that the target can be achieved soon.
