According to the British “Nature†magazine published on February 14, the research team led by Wang Zhonglin, a Chinese-American scientist, has newly developed a new type of nanofiber that can generate electrical energy. This filament, which is thinner than hair, grows out of tiny nanowires and can generate electricity by pulling, rubbing, or blowing in the breeze.
With this “fiber nanogeneratorâ€, commonplace movements such as walking and heartbeat can all be used to generate electricity in the future, and mechanical energy is therefore subtly converted into electricity. It is worth mentioning that this new “generator†uses bio-safety materials, which are non-emitting and non-polluting in the entire process and can be called “green power generation†with the greatest potential.
Ultra-fine fiber filament change "generator"
According to reports, the 47-year-old Zhong Lin Wang is a professor and a famous materials scientist at the Georgia Institute of Technology in the United States. The breakthrough made by his scientific team in the field of nano-power generation was published in the British magazine "Nature" published on the 14th. During the experiment, they put Kevlar synthetic fibers into a chemical solution and coated them with zinc oxide. The zinc oxide plated on the filaments grows radially and “long†out of the nanowires with a diameter of only 1800 percent of the hair. Fiber filaments full of nanowires are like "hair curls for ladies curls." Place two "hair curls" in parallel and give one of them a gold or other metal. The metal can form a diode-like conductive effect with zinc oxide. Then, under the drive of the motor, the two "hair curls" are rubbed against each other and pulled loose. Due to the "piezoelectric effect" of zinc oxide, deformation of nanowires can generate electrical energy.
Put on a "power generator" to listen to the iPod
It is understood that the greatest attraction of Wang Zhonglin's and other people's achievements is that as long as the clothes don't need to do any special action, the fabric can generate electricity on its own. Wang Zhonglin said: "The key point of this research is that if you are blown by wind, hear sound waves or get shocked, your clothes will generate electricity. You don't have to do special sports." Simply put, "As long as you can move, you can generate electricity." .
The successful use of nanofibers for power generation with fibers means that flexible and bendable power generators such as “power generation clothing†will become a reality in the near future. Even tents that are driven by breeze can generate electricity. According to Wang Zhonglin’s current prototype, fabrics made from such fibers will have an output of 80 milliwatts per square meter, enough to drive an i鄄Pod player or charge a cell phone battery. Therefore, it can be used for field activities for hikers or soldiers, and it can also provide power for micro sensors in biomedical or environmental monitoring.
"Green power generation" zero pollution
Compared with their previously developed DC nanogenerators, the breakthrough of fiber nanogenerators lies in the following: First, the substrate from which the nanowires are grown is replaced with a hard, expensive silicon material that is soft and inexpensive. Taking Kevlar fiber from DuPont, for example, can buy a large bundle for a few dollars. Second, the mechanical movement that drives the nanowire frictional movement is changed from the previous high-frequency ultrasonic wave to the more easily-acquired low-frequency mechanical motion.
The successful use of low-frequency mechanical movement is more groundbreaking. The mechanical energy generated by running, walking, and heartbeat can be theoretically converted into electrical energy. The energy that was once wasted in the future can be used in the future. In addition, fiber nano-generator materials are all bio-safety materials, the entire process without emissions, no pollution, called the most potential "green power generation."
