Fujitsu said Monday (September 13) that it has overcome design hurdles for a mechanism for wireless charging of electronic devices and that the company plans to use it in products to be sold in 2012.

The general idea, which Intel, MIT, and other organizations have been researching for years, offers the prospect of a laptop or phone that charges when you set it on a desk or table, potentially getting rid of some cables and making travel easier. Fujitsu has bigger ideas in mind, too: transmitting power within a computer chassis and charging electric cars, for example.

Fujitsu Laboratories has been investigating a technique proposed in 2006 that's called magnetic resonance. It uses a coil of wire and an electronic component called a capacitor to create a resonance it and the power receiver. But the technique is hampered by high complexity of computer modeling.
