The Japanese company believes a new computer modeling method makes wireless power transmission practical to build products by 2012. Here's a look at Fujitsu's technique.
Fujitsu's wireless charging demonstrated
A demonstration of Fujitsu's wireless-charging technique shows the ability to power one fan and two light bulbs at varying distances and positions compared to the charging station, the circular coil at left.
An example from Fujitsu's wireless charging computer model shows how magnetic resonance changes when the position of the the three small receiving coils are moved in relation to the one larger transmitting coil.
