科学美国人60秒:新型智能键盘可识别主人-托福听力下载

　　科学美国人60秒中文翻译：

　　Keyboards don't exactly spring to mind when you think of high-tech innovations, especially now that we have voice and even gesture controls for our gadgets. 当你想到高科技创新时键盘并不会马上浮现在你的脑中，尤其是现在具有语音甚至手势操控功能的许多电子产品正大行其道。

　　Still, a new device out of the Georgia Institute of Technology is taking typing in a smart direction. 不过乔治亚理工学院的一项新装置正将打字行为带向智能发展之路。

　　The Georgia Tech researchers have developed an intelligent keyboard that captures information about the force and length of keystrokes. 这所学院的研究人员研发出的一种智能键盘能够捕捉按键力度及长度的各种信息。

　　They say these patterns are unique to different typists and could lead to a new type of biometric security, locking out anyone who doesn't type like you do. 他们表示这种键盘的模式对每个打字者都是独一无二，而且可以引导一种新的生物识别安全性能，从而拒绝那些打字类型截然不同的人。

　　The keyboard can also power itself using something called contact electrification. 通过名为接触起电的机能这种键盘还能够自行充电。

　　It generates current when your fingertips touch the keys, which are coated with an electrode material. 当你的手指触摸按键，涂有电极材料的这种键盘会产生电流。

　　So we're talking about a wireless keypad that never needs batteries. 所以我们所讲是一种完全摆脱电池束缚的无线键盘。

　　The researchers published a paper about their intelligent keyboard in the journal ACS Nano. 研究人员们已经在《美国化学学会纳米》杂志上发表了这种智能键盘。

　　Maybe the best feature of the keyboard is that it's basically made from layers of plastic and has no mechanical keys. 也许这款键盘最大的特点是基本上是由塑料层制成而且没有机械按键。

　　That means you could drop crumbs or even spill coffee on it without any damage—forget voice recognition, now you're talking! 这意味着你可以尽情享受面包甚至咖啡而不理会给面包屑及咖啡泼洒对键盘造成的损坏—还有语音识别功能，现在你可以通过语音进行操控!
