Gecko Feet Inspire Sticky Tape

michael posted more than 10 years ago | from the move-over-duct-tape dept.

Technology 187

Makarand writes "Geckos have the remarkable ability to climb the most smooth surfaces and hang from glass ceilings with a single toe. Their feet are covered with millions of nanoscopic keratin hairs that can exert an intermolecular force - called van der Waals force - producing an adhesive effect on surfaces they walk on. Researchers at Carnegie Mellon have been able to mimic the adhesive ability of Gecko feet with a synthetic material that could find applications in new types of vehicle tires or allowing robots to climb walls. The material is made by using a mould created by a lithographic process and consists of a flexibile and strong substrate covered with 100 million nanoscopic hair each centimetre square. It might take several more years before Gecko tape is made commercially available to the wanna-be Spiderman, but he will have to thank the Gecko for that, not the spider."

Attention Michael Sims (-1, Offtopic)

Michael's a Jerk! (668185) | more than 10 years ago | (#6094164)

After months of reading your rantings without comment and having
finally stated my objections to you and your childish responses over
this last week, I permanently close further discourse with the
following:

Michael Sims, it is my firm belief that you are a dangerously demented
individual with definite dictatorial traits. You are irrational,
abusive, and intolerant of any views other than your own and insist
that only you know who each of us are better than we know ourselves.
I believe you to be psychologically unstable and a sociopath to the
extreme.

I would not be surprised to see you on the evening news or Americas
Most Wanted. You may have some technical skill and even be able to
hold a rational discussion now and then, but these are exceptions to
your character rather than the rule. You should be committed.

That said, your rantings are the stuff trolls are made of, your
opinions carry no weight, and your posts shall be kill filed. I
apologize to all who have had to read his diatribes and my recent
responses to them. We are all the dumber for having experienced Mr.
Sims.

When you multiply a radius of a 3D object by 10, you get 100 times bigger area with 1000 times bigger volume and mass.

Gecko can climb walls and ceilings because it is so small that ratio between touching area and mass is quite large. Humans would need to have huge hands to achieve same kind of ratio.

Tire design is not as easy, Gecko tires would most likely stick to dirt, not the road. It would be like braking on ball bearings.

So how much "sticky tape" can one have to certain weights/newtons?

Will a tyre foot print be enough for cars or do we need a football pitch size sticky tape?

Can 2 tonne car going at 100kph stick round any corner ? And will we then need tilting cars, like the tgv and bullet trains ?

Aug 2002... "Researchers have created two prototype glues after confirming that geckos owe their amazing ability to scamper across ceilings and cling to polished glass solely to many thousands of tiny, spatula-tipped split hairs on their toes.hese bond weakly with the molecules in any surface on which the lizards run.

The scientists, based at the University of California at Berkeley, cast two sets of imitation gecko toe hairs. Their mould was a microfilter with which biologists usually remove bacteria from solutions. They then tipped the hairs with silicon rubber or polyester.

In the lab, both materials adhered as well to most surfaces as the natural wall-crawlers. "

Peeling (2, Interesting)

Inflatable Hippo (202606) | more than 10 years ago | (#6094306)

The act of peeling tape is to apply a large force to a small area of the tape, overcomming the adhesion locally.

A Gecko may well use the same trick.

Consider this experiment: Paint your hand and plant it flat on a piece of paper. Lift your hand and the paper comes too.

Try it again but this time peel your hand away palm first then fingers then finger tips. The paper stays on the table.

This is how Spider Man does it, rent the DVD and use slow motion - It's True!

While I have not studied the domestic gecho, I can already see an application releasing existing things we have from postit notes (you can't really clean them) to velcro. Not to speak of velvet padding based on the gecho material to help anchor something in the event of earthquake... this fall under the catagory of cool beans.

Presently, with the exception of that 3m postit stuff, the only thing we have close to a reuseable adheasive that I know about is spray glue. Per the instructions on the can you apply, let dry, and it in theory stays sticky. As long as you don't mind running the risk of having green goo stuck to places. Double stick tape is also a current product i've used to mount stuff with the intent of having it removable. It's only a soso solution.

I'd be hip to a gecho solution.

Sco has been reported as using the "sticky gecko patent grabber", for those unfamilar this loveable little creature spends it's life climing up stacks of patents and attaches it self to the one you wish to lay a claim to. This was inspired by Kat in RedDwarf, "This is mine, that is mine, this is all mine".

IBM in responce has employed the use of their teenage ninga mutent ninga lawyers(TM) but presently have no defence for the sticky gecko rectroactive claim. "You try to pry it off and it just gets stuck to you, and suddenly you are the property of SCO".

SCO's defence of their use of this creature has been, "This is mine, that is mine, this is all mine".

At present, the IP of the sticky gecko patent grabber is in dispute, those critical have been known to say, "this is a really stupid idea", but strangly enough the case seems to hold some water as no one ever thought patent the idea of stealing other people's work.

What about the mighty H-bond? (1)

aelvin (265451) | more than 10 years ago | (#6094422)

Hmmm. Hydrogen bonds are an order of magnitude stronger [humboldt.edu] than van der Waals IM bonds. One practical effect of the strength of H-bonds is that water is liquid instead of gas at room temperature.

I wonder if anyone is working on an H-bond version of this stuff. Presumably, you could use 1/30th the material. Makes me wonder if you could space it out more and make it easier to peel off.

Anyone know if there are critters that use H-bonds for the same function a Gecko uses dipole-dipole stickies? If not, any ideas why? Do H-bonds just not work for this purpose, or are they selected against for some reason?

Re:What about the mighty H-bond? (0, Informative)

AlecC (512609) | more than 10 years ago | (#6094527)

H-bonds don-t work for this purpose. H-bonds only bond H to H, so unless the surface you want to climb has been treated in some way to cover it wil dangling Hs, there is nothing for you to bond to. Van der Waals force works between any two reasonably flat surfaces - and any surface is flat on a small enough scale, which is what this tape is exploiting.

Re:What about the mighty H-bond? (5, Informative)

simong_oz (321118) | more than 10 years ago | (#6094752)

sorry, but you're wrong. Hydrogen bonds are a special form of van der Waals 'bonding' which happen to be much, much stronger (as the original poster pointed out) and so they get a special name. A hydrogen bond is usually considered to be when a hydrogen atom is bonded to either N (itrogen), O (xygen) or F (luorine). F is a bit of a special case since it is so electronegative that it forms a much stronger polarisation than either O or N and it forms very, very reactcive bonds - it's why hydrofluoric acid (HF) is so dangerous.

H-bonds do not bond H to H, they cause a (part of) a bond to become polarised (the electrons are effectively dragged away from the H atom), creating a very strong van der Waals force.

Van der Waals force works between any two reasonably flat surfaces

van der Waals forces work between [bonded] atoms. A surface just has a larger area so you get more bonds in "action", hence a larger force of adhesion.

and any surface is flat on a small enough scale, which is what this tape is exploiting.

no, completely wrong - the smaller the scale, the rougher the surface. That's why surface roughness (Ra, Rs, cla) measurements are all standardised to a certain length .

The gecko exploits the fact that it has a high surface contact area to mass ratio (look at the size of the pads on the feet to it's body size).

Re:What about the mighty H-bond? (1)

I guess I should clarify that - the hydrogen bond is the (strong) van der Waals force that forms between the two separate molecules.

eg. in water, you get H--O--H...0--H2 where the "..." represents the hydrogen bond and "--" represents a covalent bond.

H-bonds can only occur between substances with hydrogen in and even then its only in special cases. They occur in compounds where hydrogen is bonded to either oxygen, nitrogen or flourine. This kind of limits what u can stick to.

In the future nerds, geeks, and dweebs of all variety will swear not by the power of duct tape to fix all problems, but gecko tape.

Greptile... (4, Interesting)

jpellino (202698) | more than 10 years ago | (#6094557)

3M make a tape called 'Greptile" that Pearl Izumi made into a set of matching handlebar tape and cycling glove. Each has lots of microscopic protrusions that make the things stick like crazy to each other - not sure how microscopic, but the ads always had EM photos of the surface. 3M also sells the raw tape. Reviews are great, but it never really caught on. For most cyclists, increased padding is prolly preferred over increased grip - you can always squeeze harder.

Nanoscopic?? (2, Insightful)

dreamchaser (49529) | more than 10 years ago | (#6094562)

Why do people have to make up new words when the term 'microscopic' is what we are really talking about. Anything that you can't see with the naked eye is microscopic...Smacks of 'hey let's throw in some high tech sounding buzzword so it looks even cooler than it is' to me.

Not that it isn't cool. It is. I want my Spider Man gloves!

Covert Ops (2, Funny)

mothrathegreat (542532) | more than 10 years ago | (#6094603)

I wonder how long the CIA and secret services around the world have been climbing around air vents planting bugs and so on using this stuff.

CRASH!!! ..... FREEZE ...... [frenzied submit clicking] .... BANG!

In all seriousness though this could be cool for so many things, walking about in zero g (not as much fun, I know) , professional thieves will love it (they're probably stealing some now). The list just goes on.

I>several more years before Gecko tape is made commercially available

The stuff already grows naturally on Geckos. Who wants to start a joint venture Gecko farm with me!

Where is the outcry over this shameless THEFT of the gecko's intellectual property??

As a CMU grad, I can say that none of us really needed help getting our hands sticky. Oops, did I say that out loud? I guess that's what happens when you go to a school that had a 70/30 ratio (I heard it may be better now) and was right down the street from Pitt. Mmmmmm...sticky hands...*drooling*

Interview (1)

Placido (209939) | more than 10 years ago | (#6095192)

I heard an interview with the scientist this morning on BBC Radio 4. The news reader asked him 3 or 4 times what were the potential uses for the tape. Every single time the scientist shot off at a tangent talking about the science and properties of the tape. "blah blah you can wipe dirt off blah blah blah it's dry blah blah blah" At the end of the 3-4 minute interview he still hadn't answered the question. The news reader laughed and said something along the lines of "you never answered the question. Next on the news is ...".

It won't work for tyres.
By the very nature of car tyres, they wear.
I would say that the nanoscopic hairs would have been broken down by the third or fourth revolution of the tyre.
