Human as an Electric Generator

“The idea is to generate electric energy from the mechanical movements of living beings”. When living beings make mechanical movements, they spend their energy some of which is converted to work. The wasted energy can be converted to electrical energy with the help of nano-generators. The nano generators have a piezo electric crystal (say ZnO) which is made up of nanoparticles. These piezo electric crystals can be placed inside the sole of shoes. When the person walks, pressure is applied on the piezoelectric crystal. When force is applied on a piezo electric crystal (or nano wires), it results in displacement of the charge on its face .This unbalances the charges and creates an electric field that produces a current when the nanowire is connected to a circuit. Each Piezo electric nano wire can produce maximum of 50mv spike. Array of nano wires can be used to produce considerable amount of power. The produced power can be used to power cell phones or some medical equipment, which a person may carry with him. By using this on animals, it can be used to power critter cam’s which allows us to observe the animal neck to neck for a longer time than battery powered critter cams.This could be beneficial to soldiers in the field, who now depend on batteries to power their electrical equipment. As long as the soldiers were moving, they could generate electricity".
