Power Your Phone While You Walk

Tired of plugging in your mobile devices? Try charging them while you walk. Scientists from Georgia Tech have created what they call the first commercially viable nanogenerator. It's a chip that uses your body as a power source.
Metro explains how it works.
"Hailed as a milestone, the tiny chip works by using zinc oxide nanowires so small that 500 could fit in a human hair. When they are strained or flexed, electricity is produced -- meaning any body movement from the pinch of a finger to a beating heart can generate power."
The researchers say this is the first of these generators that can deliver a high enough charge to power electronics. Lead researcher Z.L. Wang demonstrated to the American Chemical Society how the device produces as much electricity as a pair of AA batteries.
"The major breakthrough we have made in last year is to boost up the power output. ... So that means we have ten microwatts of energy output. How do we do this? It's just any mechanical flicking like this. There's two volts come off that."
The technology is so adaptable, it can be used practically anywhere. Wang said they've already experimented with lining a car tire with the devices. But Geek.com explains the use that's getting tech addicts really excited: no more plugging in.
"In principal, the nanowires are small enough to sew or embed into pretty much everything. ... So if they were embedded in your pants, every step you take would generate a charge of electricity that could be funneled into an iPod or a battery pack... Pretty neat, huh? We'll all be walking portable gadget chargers before we even know it."
If that's not sci-fi enough for you, there's even talk of using the human heartbeat to generate power. Tech bloggers are dreaming of heart-powered phones, but a writer for Register Hardware says it's probably premature to line up for the iPulse.
"Of course, actually implementing these devices as coronary iPod chargers isn't a top priority, but Wang's idea of a heart powered nano chip to run an implanted insulin pump is a more serious suggestion likely to get medical attention."
Wang says he hopes to bring the chips to the market in three to five years, ready to be put into shoes, tires, train tracks... Where else could they go?

厌倦了你的移动设备中插入？当你尝试给他们走。来自乔治亚理工学院的科学家创造了他们所说的第一个商业上可行的奈米发电机。这是一个芯片，它使用的电源你的身体。
地铁解释它如何工作。
“作为一个里程碑，被誉为微小的芯片采用氧化锌纳米线工程非常小，可以容纳500人的头发中当他们紧张或弯曲，电力生产 - 。意义从手指捏到任何身体运动跳动的心脏可以产生动力。“
研究人员说，这是这些发电机，可提供足够高的电荷在电力电子第一。首席研究员Z.L.王证明美国化学学会如何产生的设备作为对AA电池作为大量电能。
“的重大突破，我们在去年取得是提高了功率输出。...因此，这意味着我们有十微瓦的能量输出。如何做呢？这是任何人都觉得这机械轻弹。有两个伏来过这一点。“
该技术是如此的适应性强，可用于几乎任何地方。王在希说，他们已经有衬里的设备与汽车轮胎试验。但Geek.com使用该解释的高科技痴迷者变得非常激动：没有更多的堵漏英寸
“在校长，小到纳米线缝或嵌入到几乎一切。...因此，如果他们在你的裤子嵌入，你采取的每一步将产生的电费可分为iPod或电池漏斗包...漂亮整洁的，是吧？我们都会走便携式小工具充电器之前，我们甚至知道。“
如果这不是科幻为你够了，甚至还有人谈论使用心跳来发电。科技博客都梦想心电手机，但一人登记硬件作家表示，它可能过早排队的iPulse了。
“当然，实际执行这些设备为冠状动脉iPod的充电器是不是当务之急，但王的心电纳米芯片植入胰岛素泵运行的想法是一个更严肃的建议可能会得到医疗护理。”
王说，他希望把芯片市场在三到五年内，随时可以投入鞋，轮胎，火车轨道...他们还可以去哪里？
