Decomposed computer chip made of wood

US scientists have successfully built a new semiconductor chip made from wood that can be biodegradable.

Substitute substrates, or nanofibril cellulose (CNF) support , flexible materials made from wood. It has smooth surface and good thermal expansion. The results show that chip performance is comparable to that of existing chips.

"Wood is a natural hygroscopic material and can expand." With an epoxy coating on the surface of the CNF, we tackled two issues: moisture and surface smoothness , "said Zhiyong. Cai said.

Most mobile electronics are made from non-renewable, non-renewable and potentially toxic materials. The worrying issue today is that consumers are constantly releasing them when they switch to new devices. Researchers at the University of Wisconsin-Madison and the US Department of Agriculture hope that biodegradable semiconductor technology will solve this problem.

" Most of the material in the chip has a supporting role: we only use less than a few micrometers for the rest, and now the chip is as safe as fertilizer, you can put it in the woods and Mushrooms will destroy it, "said Science World Report quoted Zhenqiang Jack, a member of the expert group.

Biodegradable chips will have a positive impact on the environment. However, it takes a long time for new chips to be widely adopted.
