While walking to the phone to charge the anti-electric wetting intelligent shoe technology

Scientists have found a new technology to acquire energy, which can use the power of people to generate electricity, and then to smart phones, notebooks and other mobile devices to charge.
University of Wisconsin R & D personnel to find new energy access and storage technology, it can reduce the dependence of mobile devices on the battery, once the new technology, no matter where we do not have to worry about power is not enough. Technology can be used in the footwear energy collector, it can capture the energy generated by human walking, the energy stored later used.
If the shoes can collect energy, the use of the army will be very appropriate, because now soldiers often need to carry bulky batteries, radio equipment, GPS equipment, night vision goggles need batteries to use. Technology can also be used in remote areas and developing countries, where the grid is very backward.
"There is a lot of energy in human walking," says Tom Krupenkin, a developer at the University of Wisconsin. "Every shoe in theory can produce up to 10 watts of energy that is wasted in the form of heat The total of 20 watts of energy will be produced when walking, which is not a small number, and it is even larger than the power needed by most modern mobile devices.
Just extracting a small portion of these energies is enough to allow mobile devices to be used for a long time, including smartphones, tablets, laptops and flashlights. For example, a typical smartphone requires less than 2 watts of power.
The researchers used the so-called reverse electrowetting technique, which was introduced in 2011. When the conductive liquid interacts with the surface of the nanofilm coating, the mechanical energy is converted into electrical energy. The inverse electric wetting technique can produce energy that can be used, but it requires high frequency energy sources such as rapid vibration and rotational production of mechanical energy. Researchers have found a "bubble" approach to the collection of electrical energy, which combines the inverse of the wetting technology with the growth and bursting of the foam.
The equipment that makes the foam (which contains non-moving mechanical components) consists of two flat panels with small gaps in the middle, flowing liquid. The bottom plate has a small hole, compressed gas through the production of foam. The foam will gradually become larger until you can touch the top plate, and then the bubble will burst. The rapid growth and rupture of the foam will push the conductive liquid back and forth to produce electricity. Researchers' findings have been published in the "Scientific Reports" magazine.
