Scientists Invent Electronics That Dissolve In the Body 69

Posted by samzenpus
from the going-going-gone dept.
An anonymous reader writes in with a story about some new electronics that are designed to melt in your body not in your hand. "Scientists have created ultra-thin electronic devices that can 'melt away' in the body once their job is done. A new study published in the journal Science, details how scientists have created a tiny, fully functional electronic device capable of vanishing within their environment, like in the body or in water, once they are no longer needed or useful. There are already implants that dispense drugs or provide electrical stimulation but they do not dissolve. The latest creation is an early step in a technology that may benefit not only medicine, like enabling the development of medical implants that don't need to be surgically removed or the risk of long-term side effects, but also electronic waste disposal."

    I predict the first practical use of these devices will be for surveillance.

        Yes, but only by aliens, not government organisations.

        Then how can you predict it?

      A device that delivers drugs and then melts away to leave no evidence?

      The second practical use will certainly be assassination.

      I predict that the *same* dissolvable device that retails for $1200 in the US will retail for a tenth of that in Canada, Europe, Australia, etc.

      • by Anonymous Coward

        Actually, that's partially canceled out -- it's an electronic device, so instead of $120, it'll be priced at 120EUR.

          Or instead of $US0.99 it'll be $AU1.29, despite the AU dollar being worth more than the US dollar.
          • The AUD/USD parity is only in the last year or so (and just wait, I am sure the USD will get cheaper later...) However, that is not the whole story. I don't know if it is the case in AU -- but I know it is for many items in places like Canada... sometimes those price differences have to do with tariffs and such, so you might check if your government is pocketing the difference in MSRP.
            • Yes, I was just reading an article about some people who were caught smuggling cheese from the US to Canada, because Milk Boards in Canada keep prices high to make sure milk processors can get all the profit for milk while ensuring actual milk producers still can barely make a living.

            • AU charge 10% tax on most items.
    • Don't mind the miserable pessimists here on Slashdot. I think the medicinal breakthroughs will have more of an impact on humanity than all of the shady applications for this innovation combined.

      Oh Slashdot, news for luddites, as always. Just once I'd like to see a story about a new technology in which there isn't an immediate upmodded post about how it's so scary and awful.

      Tell me, how does the dissolvability of this new tech make it ideal for surveillance? Are you one of those tin foil nutcases who thinks the US is implanting tracking devices in people? If so, why do they want those devices (which are already so well hidden that they've never been found) to dissolve? If not, how exactly are they going to surreptitiously get these scary tracking devices into people?

      • by jmerlin (1010641)
        Well electronics tend to show up in medical scans. If a device dissolves, however, and is then excreted, it doesn't. Just a thought.
      • Whatever, you doubter. They're going to embed it in tinfoil, so it disolves through our skin when we put it on our heads. Duh.

        We need open source tin mines!! Of course if the government weren't stopping us we'd already have flying cars.

        Clearing evidence of surveillance? For sidestepping the need for warrants.

      I was thinking the same thing. Even with medical implants, electronic waste disposal is a problem because of the materials used, not the fact that they need to be removed. Even a more literal reading of TFS implies that our bodies will just absorb mercury, gold, silicon, lead, and so on from these new implants. (Awkward.)
      • by artor3 (1344997)

        Presumably the new implants wouldn't be made of lead and mercury and such. According to the fine article, they contain silicon, magnesium, and oxygen, all of which are naturally found in the body and play a positive role. Silicon is the only questionable one, since the human body normally only has around a gram of the stuff, but if the circuits are sufficiently tiny, they won't make much difference.

    When part of the device dissolves before the rest of it, will it malfunction? Especially if its one of these devices that provide electrical stimulation.

    Toddlers have been doing this for decades

  • Dissolving electronics will have unpredictable, and non-reproducible failure conditions. Can you imagine designing a medical device in such a way that any random part of your circuit could be randomly destroyed and yet fail in a graceful manner? It seems there's enough difficulty as it is with non-dissolving electronics.
