The device is called a biocompatible ferroelectret nanogenerator, or FENG.
该装置的名称是生物相容性铁电驻极体纳米发电器，简称FENG。
When the device is compressed by human motion, or mechanical energy, electrical energy is created.
当该装置被人体动作或机械能挤压时，就会产生电能。
Demonstration 2 videos show that with the nanogenerator, the scientists successfully operated an LCD touch screen, a bank of 20 LED lights and a flexible keyboard, all with a simple touching 3 or pressing motion and without the aid of a battery.
演示视频显示，利用这种纳米发电器，科学家们在未使用电池的情况下，仅靠简单的触碰和按压动作，成功运转了一个LCD触摸屏、一组20只的LED灯泡和一个可弯曲键盘。
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。
"What I foresee, relatively 4 soon, is the capability 5 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。
