Cyborg Cells Sense Humidity 100

Posted by CmdrTaco from the weird-science dept.
Gadgetizer writes "Mark Peplow over at Nature.com published this story on 'Cellborg Technology' yesterday: "Living bacteria have been incorporated into an electronic circuit to produce a sensitive humidity gauge. The device unites microbe and machine, taking advantage of the properties of both to make for a supersensitive sensor. "As far as we know, this is the first report of using microorganisms to make an electronic device," says Ravi Saraf, a chemist from the University of Nebraska, Lincoln, who developed the 'cellborg' with his student Vikas Berry."

      Well, currently, even the best artificial limbs are a poor substitute for the genuine article. People get artificial limbs because they have lost their natural limbs, and have no other choice -- we do not hate or shun these people any more than we hate or shun people with any other disability. However, if artificial limbs become far superior to natural limbs, people will be able to choose whether they want their (perfectly healthy) natural limbs removed in favor of mechanical ones. At that point you will certainly have fear and loathing between the people who undergo the procedure (the superior beings) and the people who don't (the all-natural people).

      I have a friend who would qualify as a "cyborg". He's hearing-impaired and has a Cochlear Implant [cochlear.com]. Social-wise, it's kind of a mixed bag. On one side of the coin, people in general are fascinated by the prospect of restoring hearing that was lost and the very idea of having a biological implant in his head. On the other side, however, the Deaf community generally shuns them as their equivalent of "tools of Satan."

      I think that you're always going to have people that favor the "natural" over the man-made, even to the point where they're completely separated from society (think about how we talk about the Amish)

      • I'm going to go out on a limb here and say that there is a small minority of deaf people who could have the implant done, but don't and think he is doing the wrong thing.

        On the other hand, probably a pretty good portion of deaf people have been deaf long enough (and through development) that they are not receptive to brain interfaces such as this anymore.

        When you lose your hearing young (or never had it), you lose (or never make) the brain /circuits/ necessary to process that sound enough to make it useful.

        No, I strongly doubt that. In that era, it should be just as easy to produce a removable exoskeleton as it would to fabricate a replacement limb. Imagine having 4 arms, or to have "go-go-gadget" pogo legs.

      Actually, measuring humidity accurately for a reasonable period of time is very difficult - things tend to corrode, gum up, rot or wear out. I can buy a 0.1C temp sensor for 50 cents, a 1% humidity sensor costs $50 and in my test environment (a greenhouse) lasts about 2 years.

    TFA suggests that the device continues to work even after the cells die. This suggests a simple physical response -- these ugly bags of mostly water tend to swell in the presence of humidity. If the device had ceased to function when the bacteria died, then we'd have something.

    In any event, it does suggest an approach to more sensitive humidity detectors using gold-coated hydrophilic particles. Replacing the bacteria with some other polymer capsules could lead to a more repeatable sensor with ultra-high sensitivity.
