It is possible that in the near future, users will not have to worry that their smartphones will discharge. American uchenyesozdali cheap and effective nanogenerator, which is capable of converting the energy of a small mechanical motion.
The device created by scientists from the Georgia Institute of Technology, one of the leading research universities in the United States. It should be noted that the possibility of the use of technology is much broader than simply charging smartphones. Excess energy produced by walking and breathing, can theoretically charge medical implants and other medical electronics, writes MIT Technology Review.
Shong Lin Wang, professor of materials science at the Institute of Technology, has worked on this problem for several years. It attracted attention piezoelectric material capable of generating electricity by mechanical forces. He artificially designed these materials at the nanoscale, and achieved great success.
Designed by Wang nanogenerator can convert from ten to fifteen percent of the mechanical motion into electricity. According to the scientist, in the long term efficiency of the device can be increased up to forty percent.
Generator the size of a fingernail is capable of producing up to eight milivatt electricity, enough for the pacemaker. Generator five-by-five centimeters can provide power 600 LEDs at a time or to charge the lithium-ion battery smartphone.
It should be noted that the new battery is very cheap to manufacture, allowing technology to become truly mass.
It is unknown whether this technology will find a place in the market. It is necessary to demonstrate that the invention is capable of generating energy in real life, not only in the laboratory, - says Yang Li, a professor of mechanical engineering at the University of Washington in Seattle. Shong Lin Wang said that he is in talks with manufacturers of smartphones.
