Seeing the 'Low Battery' alert on your smartphone is enough to send anyone into a frenzy. But a group of researchers have developed a solution that not only lets you power your own device, but allows you to share your charge with others in need - without using a power pack. 手机显示电量不足时我们就会莫名感到焦虑。一组研究人员已经找到了解决办法，不仅可以让你自己给自己的设备充电，还可以在没有电源组的情况下将自己的电量分享给需要的人。 Called PowerShare, this technology consists of flexible coils and docking aids embedded in a smartphone or smartwatch to transfer power to devices just by touching them together. 这款名为“能源分享”的设备主要由软线圈和对接工具组成，将其贴在智能手机或智能手表上，只要把另一只手机贴上去就可以“借”电来充。 There are a number of products on the market that provide Wireless Power Transfer (WPT) for smartphone users that power their phones without the need of an outlet. Although power packs and mobile hand generators are good back-ups, they can be bulky and a nuisance when traveling. 市面上可供智能手机用户在无需电源插座的情况下充电的无线输电设备不在少数。虽然一些电源组和移动手摇发电还可以起到救急作用，但是对于旅行者来说笨重又麻烦。 |
