"Interior Wood 100%." Soon, the label could be with our computers, tablets and mobile phones. Or at least they pretend that researchers at the University of Wisconsin-Madison, in collaboration with the Department of Agriculture US Forest Products Laboratory, have developed a prototype integrated circuit made almost entirely of this material.

As they explain in the journal Nature Communications, the US experts have built with cellulose nanofibers based on a chip, part of the greater proportion of raw materials is usually carried.

And what are the cellulose nanofibers? "If you take a big tree and you reduce your individual fibers, the most common result of this operation is the conventional paper. But if you break it down to the nanometer scale, you get a flexible, transparent and very robust material: the role of cellulose nanofibers, "said Cai Zhiyong, project leader.

Furthermore, once treated with resin to prevent moisture absorption, these tiny fibers are biodegradable, sustainable and heat resistant. In contrast, chips that are manufactured today typically incorporate gallium arsenide, a potentially toxic compound.
