Scientists Developing Commercially Viable Synthetic Gecko 122

Posted by Zonk
from the better-than-synthetic-llama dept.
Gordon from Seattle writes to mention a CNN article about a new way to hang out. A British aerospace team is working on a super-sticky substance they're calling "Synthetic Gecko". It mimics the hairs on a gecko's foot, and may eventually be developed as a reusable adhesive. From the article: "Each of the microscopic setae on a gecko's foot has a mushroom shaped cap on the end, less than one-thousandth of a millimeter across. This ensures that the gecko's foot is in very close contact with the surface beneath. The cumulative attractive force, called van der Waals force, of these setae allows the lizard to scurry up walls and ceilings, and even hang from polished glass surfaces. In 2003 scientists at the University of Manchester produced a one centimeter patch of 'gecko tape,' but neither the University of Manchester nor University of California teams managed to produce the material in a greater quantity, unlike Haq and Sargent, who have already tested areas larger than 10 centimeters-squared."

    Every surface outside of a clean room is coated with dust. Unless there is some cleaning mechanism, this will clog with dust and become non-sticky. Geckos probably lick their feet clean every once in a while, or have some other bio-mechanism to decontaminate their feet. How will this syntha-gecko sticky pad keep clean?
  • Wasn't one of the problems with the "gecko tape" that it was "too" sticky?
    That is; _everything_ sticks to it, thus all the dust/dirt/hair/etc. would make the tape unusable in a short time.

    Obviously, real geckos don't have this problem. You don't see them walking around with sticks, dirt and sand stuck to their feet, so how do they solve that?
    • by Anonymous Coward
      Geckoes continually "shed" the hair on their feet, and regrow new hairs. So any hairs that do happen to get extremely dirty are naturally discarded after some time, and replaced with newly-grown clean hairs.

        I doubt it would work any better on ice. The surface of ice (unless it is extremely cold) is always a thin layer of liquid water due to surface tension properties of the unattached hydrogen bonds. But since this is an exercise in surface characteristics it would be an interesting experiment to try. What if gecko feet reduce the monolayer of liquid?

        Having good adherence to sand is also not very useful since you just cover the tire with loose sand. But perhaps good adherence to a clean road might help, th

          Gecko feet would probably capillary "drink of" and absorb at least some part of that thin layer of water, like a brush or a mop does. Anyway, although at present certainly much more expensive, even if it wouldn't be much better, I am sure it wouldn't be any worse either, compared to common tire rubber.
          • by homer_ca (144738)
            Modern winter tires do that already. The top layer of the tire has microscopic pores to wick away the water from the ice. It wears quickly on pavement though, so this construction is only used in dedicated winter tires.

    As the subject states, Ive had some cycling gloves with matching bar tape for several years now with similar tech... 3M makes the stuff called Greptile, thats basically a material with a bunch of tiny hair like things on one side. When used with a similar material on whatever you want to grip, its almost like having velcro, but being able to let go with out having to pull it apart. It was designed along the same lines as well, hence the name:

    Greptile [3m.com]

    Worked pretty well, and even improved the grip between the gloves and stuff that didn't have the material on it. Only problem was the haird tend to wear out/fall off over time, so now those gloves have a few bald spots where the rubberish material has worn through and they aren't nearly as grippy

        It doesn't scale? I've pulled geckos off walls and stuff (even when they die of old age/etc they still stay stuck), and they sure stick pretty well, so given the surface area of a fair number of gecko feet, I'm not sure why that wouldn't hold up a human - at least a not too obese one (an obese tummy might get in the way of wall crawling too ;) ).

          It might not scale for other reasons, but it DEFINITELY doesn't scale for the same reason any surface effect doesn't scale.

          We're going to make something 10x as long (which assumes a ~20 cm Gecko to get to man-sized, which I think is generous.)

          So the surface area of the giant-gecko feet are 100x bigger. (10^2 - because you have length and width) But the Gecko ways 1000x as much (lenght, width, depth) So for a 10x scaling factor in length, you have 10x more mass PER surface area - in other words you stick

            So a pad area of 15mm x 15mm can hold about 2kg. So a pad area of 10cm x 10cm ( 4" x 4") should be able to hold about 90 to 100kg (200-220 pounds). Attaching four pads each of that area to a human doesn't seem like a big problem, and should provide a fair safety margin.

            That's of course assuming the synthetic gecko pad performs as well as the tokay's.
