日本富士通公司研制出一套可以同时为多个便携式电子产品（如手机、数码相机和笔记本电脑）无线充电的系统。

　　Electric cars users may also eventually be able to charge their vehicles wirelessly using the same technology，said the company, which unveiled a prototype system at the Institute of Electronics, Information and Communication Engineers conference at Osaka Prefecture University. 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 electronic device.
富士通公司在大阪府立大学电子信息通讯学会的会议上推出这一原理系统。该公司称，电动汽车的使用者未来也可以利用这种无线充电技术为汽车充电。富士通公司称，该系统是世界上首个无线充电系统。这项技术利用充电系统和电子产品之间的磁场传输电能。
