Would you call me a dirty hippie and tell me to get real? How about if Zhenqiang (Jack) Ma, a professor of electrical and computer engineering at the University of Wisconsin, told you?

According to MIT Technology Review, Ma and his colleagues have indeed made such a chip:

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 two recent demonstrations, Ma and his colleagues showed they can use nanocellulose as the support layer for radio frequency circuits that…
