The idea of ​​using wind power to make the bulb glow has always existed, and scientists have tried to find this magical material, but it has not been very successful. As early as 1605, Francis Bacon discovered what we call the phenomenon of stress luminescence. A material such as a sugar crystal can flash under the influence of force. However, there has been no breakthrough in the subsequent studies.
Now, a team of scientists from the Daegu Gyeongbuk Research Institute in Korea has successfully created a new material that can be illuminated by blowing air as if it were a display screen. This material is made of copper-doped zinc sulfide and polydisiloxane composite flexible plastic, and the color phosphor is mixed to achieve the luminescence effect. The mixture uses a flexible stress luminescent material, but if you want to change the color of light, you just need to change the ratio of the phosphor. Once the material is exposed to the wind, it will glow under the influence of the wind, and the stronger the wind, the stronger the light.
Obviously this is a huge leap forward for stress-emitting wind power materials. Previous studies have not brought any substantial benefits. This material can be effectively used in reality, such as the use of wind-powered billboards. I hope this technology will soon enter the market.
