(C) A three-dimensional voltage/current signal map of the piezoelectric charge release as the AFM probe sweeps across the nanowire array.
Recently published in the British "Science" report, the United States Georgia Institute of Technology professor, China National Nanoscience Center overseas director Wang Zhonglin and other successful conversion of mechanical energy into electrical energy in the nanoscale range, the world's smallest generator - nanogenerator . Charles Lieber, a professor of international nanotechnology and a professor at Harvard University, said, “The work is extremely exciting. It proposes a solution to a key issue in nanotechnology, which is how to power the nanodevices invented by many research groups. The professor used his first zinc oxide nanowires to convert mechanical energy into electrical energy, and he showed great creativity on this issue."
Wang Zhonglin, who is in Beijing, said in an interview with Science Times, “This is the invention that I am most excited about in this field of research for more than 10 years.†He believes that this is the most exciting and significant discovery in the international nano-field. It will cause a huge upsurge in the research of nano power sources in the entire nanoscience community.
As a director of the Georgia Institute of Technology and a Distinguished Professor of Engineering, Wang Zhonglin is also the Director of the Department of Advanced Materials and Nanotechnology at the School of Engineering, Peking University, and the Overseas Director of the National Nanoscience Center of China. This work was completed by him and his PhD student Song Jinhui. of.
Wang Zhonglin recognized the unique semiconductor, optical and biological properties of zinc oxide seven years ago and has an irreplaceable role in other nanomaterials. Therefore, his research team has been working on the synthesis of zinc oxide-based nanomaterials. Applied research. In 2001, they reported on the first synthesis of zinc oxide semiconductor material tapes in the journal Science. This paper has been cited more than 1,100 times. Later, they developed devices such as nanorings and nanohelices.
Wang Zhonglin believes that nanogenerators will have a wide range of important applications in biomedical, military, wireless communications and wireless sensing. He said: "This invention can integrate nanodevices to achieve a true nanosystem that collects mechanical energy, such as energy produced by human motion, muscle contraction, etc.; vibrational energy, such as that produced by sound waves and ultrasound; fluid energy The energy generated by body fluid flow, blood flow, and arterial contraction, and the conversion of this energy into electrical energy is provided to the nanodevice. The energy generated by this nanogenerator is sufficient for the nanodevice or system to be made, so that no nanodevices or Nano robots provide energy self-sufficiency."
