On nanotechnology expert Zhong-Lin Wang, the 2010 is excited about a breakthrough year is full of hope.
3 28, the United Kingdom "natural? Nanometer technology," reported his team's new results of two studies: high-voltage output of the nano-generators, the first time since the nanowire-based nano-drive system.
4 16, the U.S. "Science" magazine published review articles News Focus section, describes the waste energy into usable electricity generators nano. The article says: "the movement of energy into electrical energy that tiny device can drive the city, but they soon enough for handheld electronic devices and arrays of sensors can not see charging." Nano-generator concept by Zhong-Lin Wang first proposed in 2006, after the U.S. "Science" magazine nano generator as a new area of research and development launch.

Zhong-Lin Wang Georgia Institute of Technology American University Professor Dong Shi, Distinguished Professor, CAS foreign academicians. In 2006, he proposed: "Nano-generator to improve the output voltage and power of the ultimate goal is to achieve self-drive-based nano-devices, that does not require external power or battery."

Zhong-Lin Wang's group developed the world's first nano generator. Now, he said, the field of nano-power development "has reached a critical moment … … I believe, by this momentum continues, in the near future, nano-generators will affect people's daily lives."
In the article, entitled "Nano Generators: waste energy drive with ultra-small electrical appliances," the article in the U.S. "Science" magazine describes the latest breakthroughs in the field of nano-generators of the three scientists:
Princeton University chemist Mai Maike? Karpin, his team developed can be embedded in the soft silicone pressure material (PZT) nano-ribbon generator, if embedded in clothing, this kind of micro-generation function of the energy generated by the body action into mobile power;

Georgia Institute of Technology physicist Zhong-Lin Wang and his research team invented zinc oxide nano-generators can output the highest voltage so far?? 2.4 volts, while the standard AA current output voltage is 1.5 volts, and the realization of the whole based nanowires self-driven nano-system;

University of California, Berkeley, team led by mechanical engineer Li-Wei Lin, who developed a sense of power with the pressure characteristics of long nano-fibers, such as woven into clothing, sports can also be transformed into electrical energy, to charge the phone.
Karpinski commended Zhong-Lin Wang in the article is to propose the concept of the vanguard of several nano-generators. In his view, Zhong-Lin Wang group developed high-output voltage of nano-generator is a great job.

The past 20 years, Na Mike scholars on the application of nano-materials synthesis in the ascendant, especially in nano-device research. Nano-devices with low power consumption and sensitivity, macro-devices do not have the advantage. Since 2000, Zhong-Lin Wang aware of the unique zinc oxide semiconductor materials, optical and biological properties, have synthesized ZnO nanobelts, nano-rings and nano-helix. However, these studies focused on nano-devices themselves, how to solve the nano-charging power supply device is a new problem.

Pressure material generally refers to the composition of a lead zirconate titanate thin films. Back in 1880, scientists discovered that the voltage acting on the pressure materials, will make its production strain; that is, the pressure Material can convert electrical energy into mechanical energy.

2006 early in the U.S. "Science" magazine paper, Zhong-Lin Wang made through a synthesis of nanowires piezoelectric material will be mechanical energy into electricity, and the first time the principle of nano-generators.
