Researchers in the US have found a way to power mobile phones using the motion energy caused when walking. They have made a device that can be placed in a shoe and captures the energy of moving micro droplets which is converts in to electrical energy. This is already used in some watches and sensors.
What happens is the device contains liquid droplets which are converted in to electrical current from the movement. The power generated is enough to recharge a phone or laptop but a way to get the energy form the device to the handset had not yet been completely thought out. A possibility is plugging a USB cable in to the shoe or use a wireless transmitter which is more practical.
