The First Paper-Based Transistors
Roland Piquepaille found news of research out of Portugal that has resulted in the first paper-based transistors (the original article is less informative than Roland's blog). More precisely, they've made the first field effect transistors (FET) with a paper interstrate layer. According to the research team, such transistors offer the same level of performance as 'state-of-the-art, oxide-based thin film transistors produced on glass or crystalline silicon substrates.' Possible applications include disposable electronics devices, such as paper displays, smart labels, bio-applications or RFID tags. The research will be published in IEEE Electron Device Letters in September.
... smart smokes!
I like to place meaningful quotes in my sig, so people will know that I know what meaningful quotes are.

The paper is for the transistors, not snorting cocaine...
Maybe they could go with paper batteries? Google "paper batteries" for a hundred other links to the same and related stories/technologies.

Now if only they could locate my car keys. I left them near that tree over there, but it's gone too.
There was an article published many years ago in an Australian electronics magazine which described 'printegrated circuits'.
I forget which year it was, but it was the April issue.
Finally, an origrami computer that might be useful!

The INTERSTRATE layer is paper now. In a normal FET, the whole thing has a doped silicon substrate functioning as the grid and body, with a (say) metal oxide semiconductor in between as an insulator (interstrate) (MOSFET). They replaced the MOS with paper. It's still a hunk of silicon.

... I wonder what static electricity will do to these paper FETs.

Great news! This opens a whole new world of applications.
Have you not seen Read Or Die ? The Paper Master is able to do all things.
I'd imagine there's have to be some way of sealing these to prevent moisture and humidity from affecting them. It'd be nice if the sealing compound was biodegradable, too... at least to a lesser extent than the paper. Wax, perhaps?
What they really need to do is use something very common; like, I don't know, sand. That's assuming they can come up with the technology. I know, I know. I'm dreaming.

Great. Now a ream of paper will have RFID in every sheet. How am I going to print all my Revolution flyers?

ok, i confess. i'm brasilian. couldn't resist joking, mod me down at will
What ? Me, worry ?
...our pulpy, robotic overlords...
...this research isn't worth the paper it's printed on.
The same research team also said they would be releasing a CPU (codenamed "Origami") based on these transistors. It's optimised for F@H.
Prediction: American, paper-based computers will be printed on Letter paper, but European computers will use A4 paper, thus leading to worldwide incompatibilities.

This happening to anyone else?
Really, what does "interstrate" mean? The first few hits in google are to the press release.

The first transistors on paper have been published in 2005:

There is also a paper by the same authors, which I can not find right now.

Print smart money,
When will these technologies be home replicable so we can make our own computer hardware?
The next thing you know accountants start shredding their hard-copies and their soft-copies.
Surely the real news is that Roland actually added correct content to an article rather than simply copied some pieces and made an inflammatory, catchy /. submission to get more hits on his "make money fast by blogging" blog?
I think it will take more than one or two decent submission to redeem himself of all the crap submissions that caused all the agitation for the ability to filter posts by submitter and the creation of firefox add-ons specifically for filtering him.
That's what I'm really holding out for. Maybe this will be possible now, with these new paper-based transistors.

If you thought the media corps bitch about piracy.....
Just wait and see what the electronics industry say when they start losing business to people pirating electronic products with their printer.
Of course, as a printer is electronics, even the pirating machines could be pirated!
(No, of course I haven't read the article :) )

Would this be classified as going green? HA!
But soon the paper will analyze the cocaine as you snort it and if it really good maybe make a phone call or two. Hundred dollar bills phoning home when they are in large stacks... Faraday cage wallets will really be needed then...

with disk encryption. Just buy a lighter- burn current memory, pull another DIMM off the pad, insert, you're back in business.
I assumed that underclocking is required because the TP is being used to process a substance which is as "slow as shit."
Paper is an interesting substrate, because it's cheap, but also because it's a renewable resource. It literally grows on trees. It's an interesting development because it's carbon, not a silicon material. It's not even made from plastic, which we have to make from oil. Which means that it could be made from the extra pollution we suck out of the air - the old fashioned way: growing it in the ground.
What will be really interesting is if we can match that innovation by printing organic inks onto the paper to make the rest of the transistors. Carbon based "wires" on the substrate. Preferably grown from plants (or algae - I'm not picky). See if we can't grow our microelectronics, rather than manufacture it, and cut out most of the waste and pollution, while perhaps making fairly durable objects that can be easily recycled into the environment by just burying them in soil. Atop which we grow the next generation.

Just imagine beeing able to build extremely cheap wireless mesh routers and sticking them to every lamp-post in a city. You'd instantly have a completely unregulated network free of lawyers and companies and free to use.
This is actually simmilar to the microcomputer revolution. At first people only thought about putting those into mundane applications like microwave ovens or TV-sets, later people buildt their own computers around those chips, spurring the real revolution. I believe the same will happen here.

Wait a sec. You mean ... this transistors don't require heavily doped regions?
Does this mean we'll have self-destructing documents for secret note passing? Will spies have to worry about getting blown up accidentally like Chief Quimby?

The most serious materials scarcity issue which exists with transistors is not the silicon (of which there is plenty lying around), but rather, the trace metals which are used in the semiconductor doping. These trace metals are engangered and reserves of them will begin to be depleted in as soon as 10 years. Germanium for instance is predicted to become extinct in little as 10 years. The idea of a disposable semiconductor device is very disturbing as all trace metal material needs to be recycled and reused as we cannot afford to throw any of it away, we have finite trace metals to work with and it cannot be wasted like that. THere should be strict fines for throwing any electronic material into the trash due to the fact we will depleate not only trace metals, but iron and copper in only sixty years. We need to start recycling and reusing everything now or we will lead our selves to a dark ages because of our lack of foresight, when we run out of iron and copper and have not recycled and reused what we have already exrracted.

Finally! We can read our e-books on paper. The more expensive versions could even have a paper page for each page of the ebook. What an exciting future awaits!
