Companies like Energizer, Powermat USA, and now Fujitsu are in a bid to help consumers get rid the cable clutter for their mobile devices through wireless charging technology. Taking it one step further, Fujitsu claims its technology also offers the ability to design charging systems in 1/150th the time currently required, both shortening development time and paving the way to integrating wireless charging functions into mobile phones.
As it currently stands, most wireless charging technology consists of electromagnetic induction and magnetic resonance, which has been used in cordless phones and other devices.
"The drawbacks are that the method only works over short distances, and the power transmitter and power receiver need to be in alignment, so it is effectively no different than using a charging station with a wired connection," Fujitsu explains.
"By contrast, the magnetic resonance method, which was first proposed in 2006, uses a coil and capacitor as a resonator, transmitting electricity through the magnetic resonance between the power transmitter and power receiver."
If Fujitsu's rhetoric leaves you cross-eyed, don't worry about it -- the gist of it is that Fujitsu's wireless charging technology can transmit electricity over a range of up to several meters, and a single transmitter can be used to power multiple devices. Fujitsu is thinking beyond just cell phones and MP3 players here, the company claims potential applications even include electric cars.
