Smart Keyboard Gets a Charge out of You
边打字边充电
Researchers have made a secure, waterproof wireless keyboard that gets charged by the action of your fingertips as you type.

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. Still, a new device out of the Georgia Institute of Technology is taking typing in a smart direction.
当谈到高科技创新也许没人会想到键盘，特别是现在，我们都已经可以用声音和手势来控制我们的设备了。然而佐治亚理工学院（the Georgia Institute of Technology）研发的新设备，正将打字引入智能潮流。
The Georgia Tech researchers have developed an intelligent keyboard that captures information about the force and length of keystrokes. 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.
佐治亚理工学院的科研人员研发了一款智能键盘，它可以捕捉键击力度和按下时长的信息。他们说，不同打字员的打字模式都是不同的，这或许可以为生物感应安全系统提供新思路，那些打字模式不像你的人都无法被识别。
The keyboard can also power itself using something called contact electrification. It generates current when your fingertips touch the keys, which are coated with an electrode material. So we’re talking about a wireless keypad that never needs batteries.
更称奇的是，这款键盘还可以通过“接触起电”的方式来给自身充电。当你敲击涂有电极材料的按键时，会产生电流，这使得它成为一款不需要电池的无线键盘。
The researchers published a paper about their intelligent keyboard in the journal ACS Nano. [Jun Chen et al, Personalized Keystroke Dynamics for Self-Powered Human–Machine Interfacing]
研究人员在《美国化学学会·纳米》期刊上发表了关于这个智能键盘的研究成果。
Maybe the best feature of the keyboard is that it’s basically made from layers of plastic and has no mechanical keys. That means you could drop crumbs or even spill coffee on it without any damage—forget voice recognition, now you’re talking!
或许这款键盘的最大亮点在于其没有任何机械按键，只由数层塑料组成，这意味着你不用担心食物残渣掉在上面，甚至咖啡撒在上面都不会带来任何损害。所以忘记声音识别吧，来做酷炫的手指操吧！
