Shoe Charger Uses Kinetic Energy To Power Cellphones
A small nanogenerator device relies on the wearer's movements to charge gadgets on the go.
Designer Soledad Martin has developed a conceptual cellphone charger that attaches to the user’s shoe and uses its kinetic energy to power cellphones or other small gadgets. The device is a nanogenerator system and captures the kinetic energy produced while walking or running in that shoe and converts it into electric energy. When the phone needs to be charged, the user can simply attach a USB cable connecting the charger in the shoe to the phone and power it on the go.
