The Georgia Institute of Technology in the United States has developed a vibratory power generation technology that can generate more than 1,000 times more power. At the American Chemical Society (ACS) annual meeting and exhibition "the 247th ACS National Meeting & Exposition" (Dallas, Texas), Professor Wang Zhonglin of the Georgia Institute of Technology published a related paper: "Developed It can replace the new generation technology for steam turbines and believes that this technology will change the world in the near future."
Wang Zhonglin’s research team has been developing various types of vibration power generation components. This time, a component named "Triboelectric Nanogenerator (TENG)" was developed. Triboelectric refers to triboelectricity, and this time combines frictional static electricity with tiny inductors to form TENG.
Wang Zhonglin’s research team developed the original TENG in January 2012, but at the time the power generation performance was low. Afterwards, the research team used about 1 year to increase the power generation performance to about 100,000 times the initial power. Among them, 1,000 times benefited from "microfabrication of the surface of the polymer sheet, which greatly increased the surface area."
Through this technique, the ultimate conversion efficiency of vibration energy into electricity reaches an extremely high value of approximately 60%. The maximum output power per unit area is 31.2mW/cm2, and the maximum output per unit volume is 490mW/cm3. The conventional vibration power generation element was generally several tens of μW/cm 2 , and this time, the output power was 1000 times or more. A 1cm square element provides the power needed for mobile communications.
Wang Zhonglin’s research team also produced a variety of TENG prototypes and embedded them into insoles, mats, backpacks, and marine buoys for wave power generation to investigate power generation performance. According to reports, the research team is currently developing mobile phone charger products using TENG. Wang Zhonglin said, "The technology is not limited to small-scale power generation, but also can contribute to high-power generation. Not far from the practical period, it is estimated that five years will work." (Author: wild Zezhe students, the Nikkei online technology feeds!)
