Nanogenerator: Nanotechnology Risk Assessment

A nanogenerator is a device that utilizes the semiconducting and piezoelectric properties of zinc oxide nanowires. These piezoelectric nanowires are used in the conversion of mechanical energy into electrical energy. The nanogenerator produces an electric flow that is continuous from ultrasonic waves. The electric flow that a single nanowire produces can even go up to four watts per centimeter. A nanogenerator benefits from the semiconducting and piezoelectric characteristics of zinc oxide nanostructures which are able to produce micro electric charges when the nanostructures are flexed.
