  美国科学家发明纳米发电器 手指一滑动通话一星期

  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。
