The Capture of Electricity With a Shoe

Human beings are not very effective. When we walk, we lose about 20 watts of energy per second. Instead of converting calories in the lifting or moving forward, which in turn most of them in the heat dissipates quickly. While my colleagues and I had a way of collecting waste from the energy of human movement and to about 10 watts of electricity. Lets to find out about The capture of electricity with a shoe.

Electric Slide Liquid moves between the bladders. As it does, the flow is converted into electricity. 

 

Our device is based on a physical phenomenon called electrowetting: If the voltage is applied to certain fluids, the fluid moves. This means that they convert electrical energy (current) into mechanical energy (moving fluid). We have reversed the process, forcing fluid to move the electrodes. The shoe has two flexible plastic bladders, one on the heel and one at the toe. The bladder is filled with a mixture of oil and water and connected by a thin coil. Passage through the heel, which also compresses the bladder, and several milliliters of travel through the tube of fluid in the bladder in front. Enter the finger, and the process is reversed.

The tube is covered with a thin electrode layer and the liquid slides back and forth, loading the electrowetting electrodes reversed. A small battery stores energy and this energy can be accessed via a micro-USB port on the heel of the shoe. He also invented a way that the Wi-Fi to transfer the power of shoes to the battery of mobile phone. Military and police would like to have a steady supply of energy, but I suspect most people would not be happy to deal with son attached to his shoes.
