Computer chip made of wood works as well as the one in your phone
Biodegradable, wood-based computer chips can perform just as well as chips commonly used for wireless communication, according to new research.
The inventors argue that the new chips could help address the global problem of rapidly accumulating electronic waste, some of which contains potentially toxic materials. The results also show that a transparent, wood-derived material called nanocellulose paper is an attractive alternative to plastic as a surface for flexible electronics.
In conventional chip manufacturing, electronic components like transistors are made on the surface of a rigid wafer made of a semiconducting material such as silicon. Researchers at the University of Wisconsin, led by Zhenqiang (Jack) Ma, a professor of electrical and computer engineering, made the electronic components in a similar way but then used a rubber stamp to lift them from the wafer and transfer them to a new surface made of nanocellulose. This reduced the amount of semiconducting material used by a factor of up to 5,000, without sacrificing performance. Read more...
