Purpose: a new static friction material can be lit LED lights

I don't know if you like me, winter is afraid to touch a metal object, because the sudden crackling always hit me impossible to guard against static electricity. According to the Tencent digital news, is the brother of electrostatic is not very popular, and now finally researchers found new uses -- they have invented a new type of cloth, can beat to generate enough electricity to light up, even small LED lights.

This special cloth is the inventor of the Han Guocheng university professor of materials science Jinshan Wu (transliteration). According to him, this new cloth actually contains two types of material, a silver plated fiber material, another layer is coated with poly two methyl siloxane Zinc Oxide nanorods. We will make some daily activities between the two layers of static friction between the available.

In fact, the main principle and the "nature" of our junior high school science has silk friction glass will play a similar power. The friction between the two kinds of materials can exchange electrons and thus produce positive and negative. Then the two kinds of materials separately, it will produce a small current.

One of the faces of Professor Jin and his team's challenge is to find the best triboelectrification materials, they finally chose the two materials mentioned above. Through four layers, these materials can produce a maximum 170V voltage and 120 a (A) current. By testing the friction sleeve in shirt sleeves of this cloth successfully lit LED lights, six lights embedded according to the introduction, the electric power can lighten small LCD screen, and the promotion of remote keys.

Although the use of this new material generation technology also has the very big limitation, such as the current is very weak, is unlikely to use the low permeability of the material to make clothes, but does not rule out future we can find an effective method of collecting charge generated by friction, and the charge stored in the emergency battery pack, for the special case the temporary use of may.
