Marty Cooper, who created the first cell phone, says his invention has an obvious flaw: you have to constantly charge your battery.
"Keep your charger near a real nuisance," Cooper CNNMoney said in an interview. "And I think it will be an even bigger problem."
Ensure that your phone will not run out of battery is sufficiently annoying. But imagine a not so distant future in which our bodies are covered with different devices connected -wrist, lenses and clothes- all in need of charging.
"You will not want to take away all to connect," Cooper said. "That is to be loaded all the time".
There are many companies looking to do just that, to keep your loaded at all times wireless devices. Each has a different solution. Wi-Charge believes that lasers can launch signals from the roof to the cell. U-Beam commitment to sound waves to charge cell.
But Cooper believes that the winner will come from Energous technology, you want to charge your phone using radio frequencies. Cooper is part of the board of Energous.
The promise of Energous is compelling: to convert the radio waves into power to charge the batteries, wireless devices equipped with special receivers can literally get energy from the air, allowing it to charge while in your bag, pocket or wherever are.
It is not science fiction. Energous announce Monday that it received approval from the FCC for its miniature transmitter, which can feed specially equipped devices. The transmitter can feed WattUp miniature hearing aids, medical devices and other miniature wireless devices.
There are limitations to the technology adopted by the FCC includes only very small devices with embedded chips compatible with Energous technology. And those devices must be in direct contact with the transmitter WattUp Miniature. But it is also a significant achievement.
