The innovators: how tiny amounts of wind energy could light up Africa

The plastic sheets have slivers of bendable filaments that stand up and are moved by gusts of air. The filaments, which are encased in plastic, work using the piezoelectric effect – the ability of some materials to generate a charge in response to pressure. In this case, when the filaments are moved by gusts of wind, tiny pieces of energy are created. For her prototype, Slingsby used a flexible film of polyvinylidene fluoride. “They have the ability to transform strain or bending energy into electrical energy,” Slingsby said.
