Transistor made of *electron-ion conducting polymer* mixed with wood:
"The CW is prepared using a two-step strategy of wood delignification followed by wood amalgamation with a mixed electron-ion conducting polymer, poly(3,4-ethylenedioxythiophene)–polystyrene sulfonate (PEDOT:PSS)."
Similar to the "transparent wood!" story that made rounds a while back, where they took the wood out of the wood and replaced it with transparent plastic. Incredibly dishonest.
Would you read a paper on "wood coated transistors" ? :-)
I completely agree that the phrasing of the topic is misleading at best. However, the paper does add to the growing body of work on "organic" electronics. The journey of organic LEDs from concept to product is, to me, an interesting corollary. How much "metal" can you remove from electronics? How many of the elements that make electronics "toxic"? How many of the properties of the underlying organic base can you retain while still having a signal carrying capacity?
As an example;
E-"paper", made from cellulose hosted transistors, that are configured not to "switch" but to change the chemical composition of a "pixel" that changes is light absorption characteristics (and thus its "color" with respect to non-activated pixels.
Clearly a sci-fi "dream" or construction at this point, but understanding how to make cellulose a conductor while retaining the ability to make it into paper is a step toward possible realization of such an idea.
The bottom line for me is that "organic" electronics is one of those black swan type ideas that could really change a lot of things. So I collect papers like this one to track what people with time to research the questions find out. :-)
Yeah, anytime someone applies "delignification" to wood, you're left with rayon (synthetic cotton). Then they added polymers back. So it's like they mixed some plastic and some cotton together and called it wood.
I was suddenly picturing a sleek gamer desktop with unsubtle RGB lighting and acrylic panels highlighting sumptuous walnut veneers on the motherboard, cabling insulated with the smoothest silk, and a delicate aroma of apple pipe tobacco emanating from the heat sink.

For those of you who are not up to speed on your Latin, the Saxon version of this word would be "unwooding".
