Hi-tech wooden flooring can turn footsteps into electricity

Swiss scientists develop prototype nanogenerator' that produces renewable energy when trodden on

Scientists have developed technology that can turn footsteps into electricity.

By tapping into an unexpected energy source, wooden flooring, researchers from Switzerland have developed an energy-harvesting device that uses wood with a combination of a silicone coating and embedded nanocrystals to produce enough energy to power LED lightbulbs and small electronics.
