Nanogenerator wooden flooring developed by scientists can turn footsteps into electricity. This novel energy-harvesting device uses wood with a combination of a silicone coating and embedded nanocrystals. It can enable people to produce electricity just by walking.
The device is capable of producing enough energy to power LED lightbulbs and small electronics. It is based on sandwiching two pieces of wood between the electrodes. The wood pieces become electrically charged because of the contact and separation of footsteps via a phenomenon called the triboelectric effect. The silicon-coated timbers are capable of generating electricity 80 times more efficiently than the natural wood.
