"Even though we initially focused on basic research, eventually, the research that we do should lead to applications in the real world," says Panzarasa. The next step for Panzarasa and his team is to further optimize the nanogenerator with chemical coatings that are more eco-friendly and easier to implement. They also say that wood construction could help mitigate climate change by sequestering CO 2 from the environment throughout the material's lifespan. The researchers say that these features might help promote the use of wood nanogenerators as green energy sources in smart buildings. It's only a matter of engineering."īesides being efficient, sustainable, and scalable, the newly developed nanogenerator also preserves the features that make the wood useful for interior design, including its mechanical robustness and warm colors. Drill pilot holes through the plates and insert 3 1/2 screws into the studs.

Build the front frame for the generator shed from 2×4 lumber. Align the edges flush, drill pilot holes and insert 1 5/8 screws to lock them into place tightly. The functionalization approach is quite simple, and it can be scalable on an industrial level. Attach the 3/4 plywood sheets to the floor of the shed. "Spruce is cheap and available and has favorable mechanical properties. "Our focus was to demonstrate the possibility of modifying wood with relatively environmentally friendly procedures to make it triboelectric," says Panzarasa. They successfully lit up a lightbulb with the prototype when a human adult walked upon it, turning footsteps into electricity. The researchers found that a wood floor prototype with a surface area slightly smaller than a piece of paper can produce enough energy to drive household LED lamps and small electronic devices such as calculators. The device's electricity output was also stable under steady forces for up to 1,500 cycles. Together, the treatments boosted the triboelectric nanogenerator's performance: it generated 80 times more electricity than natural wood. The researchers found that a triboelectric nanogenerator made with radially cut spruce, a common wood for construction in Europe, performed the best. They also tested different types of wood to determine whether certain species or the direction in which wood is cut could influence its triboelectric properties by serving as a better scaffold for the coating. ZIF-8, a hybrid network of metal ions and organic molecules, has a higher tendency to lose electrons. To boost wood's triboelectric properties, the scientists coated one piece of the wood with polydimethylsiloxane (PDMS), a silicone that gains electrons upon contact, while functionalizing the other piece of wood with in-situ-grown nanocrystals called zeolitic imidazolate framework-8 (ZIF-8). "It means that wood has no real tendency to acquire or to lose electrons." This limits the material's ability to generate electricity, "so the challenge is making wood that is able to attract and lose electrons," Panzarasa explains. "Wood is basically triboneutral," says senior author Guido Panzarasa, group leader in the professorship of Wood Materials Science located at Eidgenössische Technische Hochschule (ETH) Zürich and Swiss Federal Laboratories for Materials Science and Technology (Empa) Dübendorf. However, there's one problem with making a nanogenerator out of wood. The electrons can transfer from one object to another, generating electricity. Like a shirt-clinging sock fresh out of the dryer, the wood pieces become electrically charged through periodic contacts and separations when stepped on, a phenomenon called the triboelectric effect. This wonderful advertisement video for an upscale flooring company gives you a good idea of what basics are offered by flooring companies as well as a great way to represent yourself and your business.The team began by transforming wood into a nanogenerator by sandwiching two pieces of functionalized wood between electrodes.

The first step to any successful business is an appropriate and catchy name to represent you. First up was a cube of the material measuring around 1.5 cm (0.6 in) to a side made using the acid bath. Owning your own flooring business can be very lucrative and is always in high demand. Both forms of the spongy wood were tested in the lab as a piezoelectric generator. The flooring company is constantly expanding due to new innovations and designs popping up every day.
