日本研发世界首个手机无线充电系统

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. 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.
该系统可以在距离电子产品几米远的地方进行无线充电。研究人员的最终目标是在公路旁建公共的“充电站”，以提供便捷的充电服务。富士通公司实验室的研究人员计划最早于2012年让采用这种系统的产品上市，但他们未透露这些产品的售价。

"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.
富士通公司在一份声明中说：“这项技术为无线充电技术与手机的整合铺平了道路，并使多种便携式电子产品不受其与充电系统的距离限制同时进行充电。”

　　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. However, phone companies warn prolonged use can damage the phones.
现在，日本的手机用户可以使用一次性便携式充电器为电池充电。在大多数火车站和便利店都可以购买这种产品。但手机公司警告说，长期使用这种充电器可能对手机造成损害。

　　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."
富士通公司还表示，希望将这项技术应用于便携式电子产品以外的领域，包括电路板或电脑芯片之间的电能传输，以及为电动汽车提供移动充电系统。
