Chinese American professor develops new type of nanofiber to make smart power generation clothing

Professor Lin Liwei and his team from the University of California, Berkeley, Taiwan, have developed a new type of nanofiber, which can generate electricity. This kind of material is expected to be made into smart power generation clothing in 3-4 years, which can be used as a charger for small electronic products

Lin Liwei, who graduated from Tsinghua University in Taiwan, came to the United States in 1999 and is currently working in the Department of mechanical engineering at Berkeley. He and Wang Junbo, a visiting scholar from the 1nstitute of electronics of the Chinese Academy of Sciences in Beijing, formed a research group. After a year and a half, they have developed the most advanced power generating nanofibers with a diameter of 1 micron, which is about 1% of human hair

Lin Liwei said in an interview with China News Agency on the 12th: “this kind of nanofiber can convert mechanical energy into electrical energy with a conversion rate of 20%, which is the highest conversion efficiency material known at present.”

how will this new material affect human life? Lin Liwei explained: “in general, the diameter of textile fibers is 10 microns, while nanofibers are only 1 micron. 1f this kind of fiber is woven into textiles and made into clothing, people can generate electricity when they walk and move. The faster you move, the more power you generate. 1n the future, there will be no need for chargers to charge mobile phones, nor for electronic watches to change batteries. “

the nanofibers, which Lin Liwei called “intelligent products”, can also be implanted into the human body” Heart patients with pacemakers don’t have to worry about the danger of not calling at that time. “

Professor Wang Zhonglin of Georgia 1nstitute of technology also developed nanofibers that can generate electricity two years ago. Compared with the research results of Lin Liwei’s team, Wang Zhonglin used inorganic materials such as zinc oxide, while Lin Liwei used organic polyvinylidene fluoride (PVDF). 1norganic materials are more fragile and difficult to generate large amounts of electricity, Lin said

Lin Liwei said: “if we get financial assistance, the smart power clothing is expected to be available within 3-4 years.”
