It′s a common irritation these days，... you′re out and about and your phone battery is running low with no way of charging it. Well，... those days may soon be over thanks to some groundbreaking work done by a group of Korean researchers. Park Se－young has more.
This little strip can turn your body heat into electricity.
Created by a group of researchers from KAIST， the Korea Advanced Institute of Science and Technology， the device was developed with a wearable phone charger in mind... and can be incorporated into clothing.
Early this year， the wearable thermoelectric generator won the UNESCO Netexplo Award， putting it at the top of a list of 10 IT innovations expected to change the world.
But the device still had its problems. It wasn′t able to store very much of the electricity it generated. Now， a team from Korea′s Institute for Basic Science has solved that problem using high－density particles that trap heat but allow electricity to flow through.
″This thermo－element is twice as efficient as previous ones. It′s also meaningful that we were able to achieve this at room temperature.″
Previous generators could only be used at high temperatures. And the new material can easily be mass produced， so researchers see other applications for the technology in a variety of industries.
″Not only can we take human body heat， we can also take wasted heat from electronics， cars and factories and turn it into electricity.″
The finding， published in the Science journal， is expected to make wearable devices like smartwatches more viable for use in daily life.
It also opens doors to further research on green energy sources that make good use of wasted heat.

It'sa共同刺激这些天，......你外出活动，您的手机电池电量低，没有办法充电。
嗯......那些日子可能很快就要结束了由于由一组韩国的研究人员做了一些开创性的工作。
朴世荣有更多的。
这个小条可以把你体内的热量转化为电能。
创建于一组研究人员来自KAIST，科学技术的韩国高等研究所，该设备是一个可穿戴式手机充电器考虑开发......，可以并入衣服。
今年年初，穿戴式热电发电机荣获联合国教科文组织Netexplo奖，把它在希望改变世界的10 IT创新列表的顶部。
但设备仍然有其问题。
它不能储存很多它产生的电力。
现在，韩国的研究所基本科学团队已经解决了采用高密度的问题粒子陷阱热量，但允许电力流过。
“这个热电偶是两倍效率是以前的。它也有意义，我们能够在室温下，以实现这一目标。“
以前发电机只能在高温下使用。
和新的材料可以很容易地大量生产，因此，研究人员认为，在各种行业的其他应用程序的技术。
“我们不仅可以利用人体热量，我们还可以浪费的热量从电子产品，汽车和工厂，并把它转化为电能。”
这一发现发表在科学杂志上，有望使像smartwatches可穿戴设备更可行的在日常生活中使用。
它也打开大门，对绿色能源的充分利用废热的进一步研究。
