    University of Wisconsin-Madison official website recently announced that the school materials, associate professor Wang Xudong led his team to develop a cheap and easy way to step on the floor of the footsteps of power can be converted into electrical energy, so the floor change Into a more "green" products. Related research published in the "nano-energy" magazine.

    The new method uses a common and often discarded material - wood pulp. Wood pulp mainly consists of wood fiber composed of nanofibers, is a common component in the floor. These nanofibers are chemically treated and, when combined with untreated nanofibres, generate electricity.

The new material converts walking power into electrical energy
    "The chemically treated nanofiber layer and the un-chemically treated nanofiber layer are wrapped in cardboard. The two layers of nanofibers have different electrical properties and the electrons flow from one layer to the other, Current .Packed with two layers of nano-wood pulp fiber cardboard, high-pressure technology can be integrated into the wood floor. "Wang Xudong said in an interview with Science and Technology Daily reporter, this technology is easy to integrate into the market of any kind of wood flooring in.
     When the two layers of nanofibers are integrated into the floor, they can generate electrical energy, illuminate the house's lighting, or be used to charge the battery. Wood pulp is extremely cheap, rich in resources, recyclable and biodegradable, combined with the new technology of wood flooring and ordinary floor will be the same, everyone can afford. There have been reports of the use of walking materials to generate electricity, but those materials are often used in ceramics and metal, the cost is relatively high.

     Wang Xudong, in addition to cheap, they experiment through the nano-pulp fiber collection of energy and service life of the efficiency of the study. Preliminary testing has shown that new materials can be used millions of times. "We can not convert this number to measure the number of years of service life of the floor, but after appropriate design changes, new materials will be able to exceed the floor life.

    The test also proved that the floor in this new material on each step of the power generated, which can light up 35 LED bulbs.

Roadside energy harvesting technology sought after

     Over the years, Wang Xudong team has been studying the use of vibration to generate electricity, testing a variety of materials, optimization known as the "friction of nano-power generation equipment," the relevant technology. Clothes static electricity is a friction electrification, a lot of wearable electronic equipment is the use of this friction electrification phenomenon to get electricity. While wood pulp nanofibers once again extend the range of available sources of mechanical energy.

    Wang Xudong's research breakthrough is the latest achievement in the field of green energy research - the roadside energy harvesting technology. "Roadside energy harvesting techniques need only be considered where there is enough energy to collect and use, as long as there are activities where people can consider collecting." Wang Xudong said, "One idea is to develop wearable equipment, another idea is To collect the energy density of the local shuttle-intensive equipment, such as our research and development of the floor technology. "Stadiums, shopping centers and other places more crowded, and crowded aisles, etc., the installation of this new technology to capture the energy of the floor, Large power. The functional nanofibers that collect energy are less than a millimeter thick, so multiple layers of such functional units can be implanted to increase power production and the floor will not be significantly thickened after implantation.

The future or a strong complement of solar energy

     Roadside energy harvesting technology is in some ways more competitive than solar energy, and it does not rely on weather conditions, so many researchers believe it will take an important place in the development of alternative energy sources that replace fossil fuels.

     However, the University of New South Wales researcher Aristel? Sproul that, with the existing power generation floor, the new materials and other green energy compared to no advantage at all. "If you want green energy to be socially beneficial, you should look for solar or wind energy, and while new materials are innovative in ideas, they may not be meaningful."

     Wang Xudong retorted this, the new material is a powerful complement to solar energy. "Our philosophy is to transform the energy wasted in our lives into usable electrical energy, which has the advantage that solar energy can not be used, for example, in underground buildings where sunlight is not available, or where sunlight is not sufficient.

    Wang Xudong has applied to the university, the new material power generation prototype set in the campus, for students to carry out publicity and education. They will also continue to optimize the performance of various studies.
