size and micro-electro-mechanical systems micro-generator, but their size is still too large, volume of about 1 cubic centimeters to 75 cubic centimeters ranging work the vibration frequency range of 50 Hz to 5,000 Hz between. A two-layer structure of the lead zirconate titanate cantilever having one end fixed and the other end place a heavy object, constitutes a typical piezoelectric generator, the entire structure is similar to the situation in the diver standing on the springboard. When the gravity-driven when the cantilever is bent downward,[url=http://markseducation.com/louis-vuitton/cheap-louis-vuitton/]markseducation.com/louis-vuitton/cheap-louis-vuitton/[/url], the upper portion of the piezoelectric layer by the tensile stress, while the lower part of the subject to compressive stress, resulting in both the upper and lower surface of the cantilever respectively generate positive and negative electric potential. The weight vibrates up and down,[url=http://www.kdderr.com/oakley-sunglasses-outlet/]Oakley Sunglasses Outlet[/url], alternating electrical potential will be generated. However, due to the larger size of this generator, heavy shock by gravity to drive the last two years,[url=http://www.rasolallah.com/ray-ban-sunglasses/]www.rasolallah.com/ray-ban-sunglasses/[/url], our research team at the Georgia Institute of Technology, is committed to the nano-scale piezoelectric generators. This generator size in the nanometer scale, in this scale, the nature of things has changed. Such as gravity,[url=http://markseducation.com/louboutin/cheap-christian-louboutin/]markseducation.com/louboutin/cheap-christian-louboutin/[/url], which in the macro world is in a very important position in the nano world; relatively chemically joint force and intermolecular forces in terms of the impact it will have much weaker at the nanometer scale, a joint force of chemical bonds and intermolecular forces occupy a dominant position, the gravity effect is very small. Researchers have to change the design ideas in the nano world, the effect of gravity is no longer obvious. If somebody wants to build a nano-sized cantilever piezoelectric effect generator, he will find that gravity is almost not produce sustained vibration of the cantilever, the generator will not work. So we have to change the nano-generator design ideas. Our research team original development of a series of nano-technology, the mechanical energy (such as body movement and muscle contractions), the vibration energy (e.g., sonic and ultrasonic), and hydraulic energy (such as body fluids and blood flow) is converted into electrical energy, thus drive nanodevices the late 1990s,[url=http://markseducation.com/oakley/cheap-oakley-sunglasses/]Cheap Oakley Sunglasses[/url], my main research interests are carbon nanotubes (carbon nanotube). We invented a series of in situ microscopy (situ microscopy), to measure the mechanical,[url=http://markseducation.com/coach/coach-handbags-sale/]markseducation.com/coach/coach-handbags-sale/[/url], electrical and field emission properties of single carbon nanotubes. However, it has been unable to effectively
