Wear raincoats to receive wind and rain to generate electricity! The team of the materials department of National Chung Hsing University felt that the line of sight was very dangerous when it rained. It took 1 year to study and successfully used the coating on the waterproof cloth to increase the static electricity generated by the friction of the clothes and convert it into electricity. The price was cheap. Open a new vision of green energy and get on the international journal of Cutting-edge Science.

Put on the sneakers made with the newly developed nano waterproof power generation fabric, the R&D team member, Xingda graduate student Xiao Yongzhen walked around, and the LED lights installed behind the shoes lit up. Lai Yingzhi, an assistant professor at Xingda Materials Department, said that the fabric is modified on the existing waterproof fabric and coated with a polymer nano-coating that allows it to extract wind and rain energy and convert it into electricity.

Lai Yingzhi and Xiao Yongxi, graduate student Wu Xingmei began research a year ago. He said that at first, it was felt that when it rained, the line of sight was unclear. If it was dangerous to use an umbrella, it began to conceive and how to convert water energy into electricity and make During the research and development period, the bottleneck was encountered because the cloth was stuck together and could not be frictionally charged. After the multi-layer structure was separated, the problem was solved.

How much power can be generated by cloth power generation? Lai Yingzhi pointed out that if the area of ​​A4 paper size is calculated, it can generate 30 to 40 Ford, which can drive LED lights or watch power, and the mechanical energy generated by human movement can convert more power, and each raincoat costs about 50 Taiwan dollars. Compared with existing generators, power generation blades, etc., it is convenient and inexpensive.

In addition to being used as a raincoat or windbreaker fabric, the team also used the characteristics of mechanical conversion of electric energy to develop an automatic drive sensor that does not require a power supply. It can be used as a keyboard, a computer or a mobile phone as long as it is touched. Lai Yingzhi said that the future hopes A smart wearable app that is self-sufficiently charged in a way that is worn by the human body.

Lai Yingzhi emphasized that the newly developed nano waterproof power generation fabrics are quite durable, and most of them can be thrown into the washing machine for cleaning. The scope of application is quite wide, such as the flag used during the election in Taiwan, camping equipment or roofs of houses, etc., the future. I hope to develop towards commercialization and reduce costs through mass production.
