再也不怕手机没电：首款无电池手机诞生

手机的续航能力不行，老是得充电？很快你就不用再为此烦恼了。美国科学家已经研发出了不需要电池的手机，让你“永久续航”。

Your future phone may never need to be charged.

未来你的手机可能再也不需要充电了。

That's the exciting implication of new research out of the University of Washington, where researchers have created a mobile phone prototype that doesn't require a battery to operate.

这项激动人心的新研究成果出自华盛顿大学，那里的研究人员已经研发出一个无需电池便可运行的手机模型。

再也不怕手机没电：首款无电池手机诞生1

The astonishingly efficient prototype requires just 3.5 microwatts of juice, and it employs an innovative approach to avoid the need for a battery cell. Instead, it uses ambient power from radio signals and light — its onboard solar cell is "roughly the size of a grain of rice" — to transmit a signal back to a base station 50 feet away.

该模型的用电效率出奇的高，仅需3.5毫瓦的电量即可运行，还配备了一项“无电池”的创新技术。它配备的太阳能电池与一粒米的大小差不多，电能来源于周围的光或无线信号，从环境中获取能量，并能将信号传输回50英尺外的基站。

The prototype itself is made of simple materials: capacitive touch buttons, a circuit board, and other "off the shelf" components. More impressive is that the team of scientists were able to create a custom base station to transmit the signal with such a small amount of power.
