Researchers In Switzerland Get Electricity From Wood

fahrbot-bot shares a report from Electrek: Researchers at ETH Zurich and Empa have chemically modified wood and made it more compressible, turning it into a mini-generator. When compressed, it generates an electrical voltage. Such wood could serve as a biosensor or as a building material that harvests energy. Ingo Burgert and his team at public research university ETH Zurich and Swiss federal laboratory Empa have proven that wood is much more than just a building material. Their research enhances the properties of wood in order to use it for new applications. For instance, they have already developed high-strength, water-repellent, and magnetizable wood. Now, together with the Empa research group led by Francis Schwarze, the team has used one chemical and one biological process to generate electrical voltage from a type of wood sponge. In doing so, they amplify what is known as the "piezoelectric effect" of wood. The findings appear in the journal Science Advances.
