London: The tangled chargers could soon be
a thing of past, as Japanese scientists have developed a
system that would allow you recharge your mobile phones and
Developed by Japanese technology firm Fujitsu, the
system is capable of simultaneously charging multiple portable
electronic devices such as mobile phones, digital cameras and
laptop computers without the need for cable connections.
According to the company, electric cars users may also
eventually be able to charge their vehicles wirelessly using
the same system that will be available by 2012.
Fujitsu has recently unveiled a prototype system at an
Institute of Electronics, Information and Communication
Engineers conference at Osaka Prefecture University.
"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 company said in a statement.
Claiming to be the world`s first of its kind, the
technology works on the basis of the transmission of
electricity using magnetic fields between the charger and the
The system enables wireless charging at distances of up
to several metres, with the ultimate aim of installing public
"charging spots" on the streets in order to enable easy
charging around the clock, the Telegraph reported.
Scientists at Fujitsu Laboratories are planning to
commercially sell products incorporating the new wireless
charging system as early as 2012 but did not disclose how much
they would cost.
The company hopes that the soaring popularity of
portable electronic devices ranging from iPads to e-readers is
expected to fuel a boom in wireless recharging technology
developments over the coming decade.
Mobile phone users in Japan can currently top up their
batteries using disposable portable plug-in battery-operated
devices available at most train stations and convenience
stores although phone companies warn prolonged use can
damage the phones.
The new system by Fujitsu, however, is significantly
more sophisticated and represents the next generation of
portable recharging systems using highly tuned wireless
The company added: "We are also looking at applying the
results of this work to fields other than portable
electronics, including power transmission between circuit
boards or computer chips, and providing mobile charging
systems for electric cars."
