In two years time, you may be able to charge your mobile phone without the need for cables…
Japanese firm Fujitsu has developed a wireless recharging system using magnetic technology which it hopes to put in products and sell in 2012.
The firm says that this technology not only promises more compact and more efficient power transmitters and receivers, it also offers the ability to design charging systems in 1/150th the time currently required.
The system is capable of simultaneously charging multiple portable electronic devices. One test found efficiently charging three devices, took roughly 10 minutes, or 1/150th the time it had taken before. Even with multiple transmitters and receivers, the design time is dramatically reduced.
In addition to dramatically shortening development times, this technology paves the way to integrating compact wireless charging functions into mobile phones and enabling multiple portable devices to be charged simultaneously without any restrictions on their position with respect to the charger.
The method, known as magnetic resonance, uses a coil and capacitor as a resonator, transmitting electricity through the magnetic resonance between the power transmitter and power receiver. This method can transmit electricity over a range of up to several meters, and because a single transmitter can power multiple receiving devices, developments are under way for a broad range of potential applications.
The company says these could include power transmission between circuit boards or computer chips, and providing mobile charging systems for electric cars.
