Xerox Claims Printable Electronics Breakthrough

Posted by samzenpus on from the shocker-approved dept.

adeelarshad82 writes "Xerox announced a new silver ink that it's calling a breakthrough in printable electronics, a leading-edge concept that's generated a lot of discussion but few actual products to date. Why? Precisely because of the issues that Xerox claims to have addressed. In concept, printable electronics is just what it sounds like: using a printer, basically an inkjet, to print electronic circuits. If this can be done reliably, electronic devices can be printed for far less than current methods cost. One can also print the devices on a variety of new materials. The possibilities range from printing on flexible plastic, to paper and cardboard, to fabric."

    So, how long till people start downloading designs to print them out at home?

      Well that would be a great system, especially for DIY and prototype circuits. No more etch and hassling with masks. The FA is pretty light on details (which appears to be official Slashdot policy these days) and so I don't understand where the 'components' come from. Do you just glue your IC down to the paper / plastic / textile base or does this create the components de novo (rather unlikely for complicated things like an IC, but conceivable for resistors, caps, etc.)?

      Might change the definition of an 'underwire bra' significantly.

      The article only mentions a reduction in silver ink printing temperature allowing for printing on plastics and cardboard, as well as functioning well in open air without being a clean room environment. That tells me it's primarily a PWB printer, no mention of semiconductors for ICs. Of course, it's possible, with enough resolution, to print a resistor or capacitor. However, I believe this technology will just produce the conductors, allowing you to solder any components (hopefully it is able to be soldered to) needed.

      My question is if they can make multiple layer circuits. This should be pretty easy, just print a layer of insulator on top, with holes for any connections between layers. Also curious what their resolution and tolerances are. Obviously this isn't going to go into high-performance industrial applications any time soon, but if it's possible to make reasonable reliable circuits with tolerances to the mil (0.001"), DIYers will be able to make (and pay for!) circuits they never dreamed of doing before.

    I think it would be great if we can attach an electronic version of a printed document so that we can verify its authenticity using digital signatures.

  3. The death of photography makes it possible by Kupfernigk · · Score: 3, Interesting

    Until the end of the 20th century, a major market for silver was photography. The digital camera and the inkjet printer have slowly destroyed that market and replaced it with digital imaging. Now there's a new use for the silver which, presumably, had digital imaging not come along would have been much more expensive. (Although color photography ends up more or less silver free and there was considerable recycling, there was still a steady consumption of silver, and as the photography market democratised, the amount of silver in use at a given time was steadily increasing.)

  4. Not too much hype in summary by wisebabo · · Score: 4, Interesting

    When I saw the sentence starting "The possibilities..." I mentally filled it in with "are endless".

    I was surprised (and a little gratified) to see the summary actually enumerating some of the possibilities instead of hyping it as is normally done. That's good!

    Lots of stuff costs 70x more than crude oil. What was surprising about that link was that HP ink costs twice as much as human blood.

    I know a guy who used to work at HP. He was an ink chemist, although not personally responsible for the prices you pay ;-) He's a diehard electronics hobbyist, and he's been printing his own boards this way for several years now. I've seen some of his boards, and they seem to be very durable. And this was with an inkjet printer he hacked himself, with home-made ink (he won't tell me what's in it)
