believe it or not just by your mobile phone battery ran full back
If by chance you’re in a place where there is no place for a pulled-charge gadgets, you may be able to get the energy back to the gadget just by running.
A finding managed to turn the movement ran into an electrical energy. The energy conversion medium contained in a three-centimeter-sized device that is equipped with a 20,000 square nanowires.
By Big News Network reported on Thursday (19/05/2011), the technology was discovered by scientists from Georgia Tech, a quick energy storage device made of piezoelectric material.
Piezoelectric materials can generate electrical energy from a pull or push movement.
Within three to five years into the future, piezoelectric nanowires can be pinned on the shirt and the right shoe so that it can easily be taken anywhere to drain the energy for your laptop or mobile phone, just with a small step.
“This is a new stage for the design of technology that is useful in the future. Piezoelectric energy can produce more than 1.26 volts,” said Professor ZL Wang of Georgia Tech.
In generating energy from movement, the researchers concluded that the way is the most effective way to develop a method that worked at low frequencies and based on the flexibility of its material elements.
ZnO nanowires combined with these methods. At the same time, the researchers say the real advantage of this technology is that the nanowires can be grown easily on a variety of surfaces, and nanogenerator will work in air or liquid.
Type of surface nanowires that could make them thrive in metal, ceramic, polymer, clothing and tents. “Simply put, this technology can be used to generate energy under any circumstances as long as there is movement. Nanogenerator to be particularly important for needs while on the move, where they are far from energy sources and need to use sensors or communication devices.” said Mr.. Wang.
Wang and his team do everything possible to get around the zinc oxide nanowires that can blend with nanogenerator. A zinc oxide nanowire has a visible form. It measures only 50 to 200 nanometers and a length of five microns.
Three centimeter-sized device that is equipped with a 20,000 square nanowire side by side, and two thin electrodes flanking the entire nanowire.
A hard enough emphasis in these devices can generate 30 times more energy. Even if the zinc oxide nanowires of gallium nitride is replaced with the rendered output can be 10 times larger.
Besides being able to produce energy, piezoelectric can help detect fire and weather data present in a region
