Boffins have developed a #biodegradable semiconductor chip made almost entirely of wood in an effort to alleviate the environmental burden of electronic devices.
Technicians from the University of Wisconsin-Madison, in collaboration with the Department of Agriculture Forest Products Laboratory (FPL), have demonstrated the feasibility of replacing the substrate of a computer chip with cellulose nanofibril (CNF), a flexible, biodegradable material made from wood.
In the abstract to the article, titled High-performance green flexible electronics based on biodegradable cellulose nanofibril paper, and published in Nature Communications, the researchers claim to “report high-performance flexible microwave and digital electronics that consume the smallest amount of potentially toxic materials on biobased, biodegradable and flexible cellulose nanofibril papers”.
