The movement of finger swipes may soon be able to charge our cellphones.

　　只需滑动手指就能够立马给我们的手机充电了。

　　Researchers at Michigan State University has created a new way to harvest energy from human motion, using a flexible, thin and non-toxic device.

　　密歇根州立大学的研究人员们已经发明了一种新的方式，通过使用一个灵活、稀薄和无毒的设备从人体移动中收集能量。

　　“We’re on the path toward wearable devices powered by human motion," said Nelson Sepulveda, associate professor of electrical and computer engineering and lead investigator of the project.

　　电气与电脑工程副教授、该项目领头研究人员尼尔逊·塞普尔韦达表示：“我们就要制成由人体运动供能的可携带设备了。”

　　The device is called a biocompatible ferroelectret nanogenerator, or FENG, in the journal Nano Energy.

　　该设备在《纳米能源》上被称为生物相容性聚丙烯铁电体纳米发电器，或者是FENG。

　　Demonstration videos show that with the low-cost device, the scientists successfully operated an LCD touch screen, a bank of 20 LED lights and a flexible keyboard, all with a simple touching or pressing motion and without the aid of a battery.

　　演示视频显示，凭借这一低成本设备，科学家们成功运转了一个LCD触摸屏，一组20只的LED灯泡和一个键盘，所有这些都采用了一个简单的触摸或按压动作而没有借助电池。

　　The nanogenerator used to power the LED lights was palm-sized, while the device used to power the touch screen was as small as a finger.

　　用来给LED灯泡发电的纳米发电器只有手掌大小，而用来给触摸屏发电的设备只有手指大小。

　　According to the study, the film-like substrate consists of a silicone wafer.

　　根据这项研究，这个胶片似的薄膜有一个多晶硅组成。

　　When the device is compressed by human motion, electrical energy is created. Impressively, the device also becomes more powerful when folded.

　　当该设备被人体运动压缩时，电能就会产生。令人难忘的是，它在被折叠时能量更大。

　　"What I foresee, relatively soon, is the capability of not having to charge your cell phone for an entire week, because that energy will be produced by your movement," said Sepulveda in a statement.

　　“在不久的将来，我预见人们整个星期都不用给手机充电了，因为电能在你的手指划动屏幕的时候，就已悄然生成。”塞普尔韦达在声明中说道。

　　Researchers believe FENG is "a promising method in the field of mechanical-energy harvesting," which is aided by its advantages, such as light weight, flexible, biocompatible, scalable, low-cost and robust.

　　研究人员们相信，FENG是“一个在收集机械能领域上十分可观的设备”，它有着轻型、灵活、生物压缩、可伸缩、低成本和质地较硬等优势。
