Transparent Transistors Printed On Paper
MTorrice writes "To make light-weight, inexpensive electronics using renewable materials, scientists have turned to a technology that is almost 2,000 years old: paper. Researchers fabricated organic transistors on a transparent, exceptionally smooth type of paper called nanopaper. This material has cellulose fibers that are only 10 nm in diameter. The nanopaper transistors are about 84% transparent, and their performance decreases only slightly when bent."
It will be nice when we could print designs once made for fpga.

This is confusing. Is it green or is it transparent? Maybe it's a light green. Just make up your mind.
Why is Snark Required?
Moron. I'm pretty sure your only interest is in rolling paper.
If it keeps joints from "canoeing" I'm all for this transparent transistors rolling paper technology.
Be seeing you...
That is certainly a lot more modern, than silicone, which is about 14 billion years old.
Could we skip this bullshit? This nanopaper most certainly don't have too much in common with the paper made 2000 years ago.
Real life is overrated.
. . . do you end up with a raging fire . . . ?

It is futile to resistor.
Seriously, why don't we just go ahead and print with gasoline.
Paper burns pretty easily and I'd hate to see a processor printed on paper trying to render a 3d scene.
I'm guessing a lot less would start a fire.
How about peel and stick sheet of transistors so it could be transferred to something a bit less volatile.

And while the nanopaper may be biodegradable, I am wondering about the carbon nanotubes they are printing on top (as conductors). While the toxicity of carbon nanotubes is still being studied, there are good indications that they might behave similar to asbestos fibres. So not something you would necessarily want to throw on your compost heap.
Free, as in your money being freed from the confines of your account.
Apparently (from TFA) the purpose for printing on a transparent substrate has to do with creating light-emitting display technology (from cheap, renewable resources, with a low recycling impact). So, probably much less transistor-dense than your great balls of fire GPU.

They'll need different Unicode characters to go from TTL to CMOS. Using those, they can build FPGAs.
Yes. Thank you for all coming today. I have here, in my hand, a new type of transistor that I have printed on this ORDINARY piece of paper. ... ... ... ...
What?
Of course you cant see them - they're transparent.
Do they work? Of course they do, and Jimmy here has a nice computer simulation of the process.
No, of course we can't demonstrate on the real thing, we still have to work out the interconnects and external interface, but trust me - they're on here.
Yes, I have printed what is essentially invisible transistors on this paper, and it will change the world. I just need a few million dollars in funding to help me work out some of the critical issues.
Is it just my observation, or are there way too many stupid people in the world?
Really, bendable and transparent? I want my transistors fast and low power. It's just becoming silly.
Looks like we'll be watching and trying not to hear poor renditions of happy birthday in the not too distant future.
A fool throws a stone into a well and a thousand sages can not remove it.
Why do these renewable fanatics (not neccessarily these scientists, maybe the journos reporting this) always pick on the wrong things to renew. Looking around things that are manufactured - and discarded - the weight of transistors cannot constitute even 0.0001% of it all.
Why don't the greenies pick on something like the fact that many people rip out and replace their bathrooms and kitchens and general furniture every five years.
Unfortunately, making things "renewable", and hence compromising their robustness and lifetime, leads into a downward spiral in which people have to replace things frequently, leading to even more waste of material and energy, notwithstanding their "renewabilty". A transistor made of paper - who the heck is going to sit there at the end of its life and pick off the paper to recycle it? I think that even the up-country Chinese 8-year-olds who normally do this work will draw the line at that.
Moron. I'm pretty sure your only interest is in rolling paper.
How do you keep the paper cool?
If the paper is nearly transparent, then could you have a 3D display?
Now we can see electrons diffusing along the mesa, falling into holes and being swept away by an avalanche!
are now a step closer..
It's actually pretty hard to make paper burn with just heat. Unless you add a flame (An ongoing reaction.) your average GPU will melt long before the paper ignites.
There are of course plenty of different type of papers. For example the paper used in surge resistant capacitors is pretty durable.
