Static electricity has new uses: friction cloth can light 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.

The special cloth inventor is Professor of materials science at Han Guocheng's University of victoria. According to him, this new cloth actually contains two kinds of materials, one is silver plated fiber material, and the other layer is coated with poly two siloxane Zinc Oxide nanorods. Some of our daily activities will make the two layers of friction between each other, resulting in the use of static electricity.

In fact, the main principle and the "nature" of our junior high school science has silk friction glass will play a similar power. By friction, electrons can be exchanged between the two materials and then produce positive and negative poles. Then, when the two materials are separated, a small current is produced.

One of the challenges facing Professor Kim and his team was to find the best material for friction, and eventually chose the two materials mentioned earlier. By stacking the four layers, these materials produce the highest 170V voltage and 120 a (A) current. By rubbing the fabric around the sleeve of the shirt, the tester successfully lit six embedded LED lights, introducing power to light a small LCD screen and pushing a remote control car key.

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.
