According to foreign media reports, when people walk or run, they will generate energy. Although most of the energy burns calories and keeps people healthy, some of the mechanical energy is wasted on the sole wear. Over the years, people have devoted a lot of energy to developing a device that converts mechanical energy into electrical energy. For example, people hold power to make a flashlight light up; walking and stepping on the sidewalk tiles generate electricity; wind energy blades are converted into electrical energy. In fact, this is just the tip of the iceberg where people create electricity. Carnegie Mellon University in the United States has recently developed a “power insole†that can inadvertently convert human kinetic energy into electrical energy. It is not only used in the United States but also in poor countries with imperfect electric facilities. It is reported that the designers of the “power insole†are Matt Stanton and Hahna Alexander, which is a kind of insole that can be placed in any shoe. The user only needs to put the insole into it. In the shoe, the charging wire is connected to a battery pack fixed to the ankle or the front end of the shoe through a shoelace hole, and the energy generated when walking for 3.2-4 kilometers is enough to fully charge an iphone mobile phone. At present, the research team is testing this power insole and hopes to go on sale in 2014. A "buy one get one free" activity will be launched to enable developing country residents to purchase this smart insole. "Power Insole" won second place in Colorado's 2013 second healthy and sustainable lifestyle design competition. This insole retails for $140.
