I guess you're going to make some soon? make sure the wax is almost perfectly flat before cutting the grooves... which should definitely be done by a machine 🤔 if you're able to get those ridges longer, it should be able to stick to rougher surfaces, since they can comply a lot better.

Jason Doust 8 ヶ月前

I had my equivalent of a Disney moment in my garden a few weeks ago when a gecko landed on the back of my hand. Having the real thing walk across my skin was remarkable. I swear that I could feel the pads of its feet moulding to the profile of my skin and this video kind of confirms that experience. (Beautiful little shimmering speckled beasty!) I let it down gently onto a tussock grass and it went on its way. Biomimetics has much to teach us.

I've always thought that wander walls forces are very weak. I knew that it acted between the atomic sheets of graphite and holds the entire thing together but after seeing this video I think completely different about this amazing force which could handle sheer strength. Imagine how much strong it would be if we were to replicate it exactly like that of a gecko has!

Just for clarification all forces between partial charged atoms are called van der waals forces what he is specifically referring to is called London dispersion forces

are there a limit to how much you can use each piece of gecko adhesive? do the small structures degrade overtime so its not as sticky anymore?

Great work you're doing. Nature is so inspiring and we have so much to learn. Question: did you do tests, how your product works/doesn't work on anti-stick (Lotus inspired) materials? Keep up the good work :)

Tobi 8 ヶ月前

Would it be possible to cover a pipe with the material so that it could be used instead of tire profile. I think it would create way more friction/traction than any slick tire would in good conditions. The pipe would just have to be long enough to have enough contact points… please try and tell me how it went, would be super cool

I assume it's not currently available as a commercial product, but I might have a non-robotics use for it.. is there a way to get some to experiment? This is just amazing.

Zachary O'Hare 8 ヶ月前

Amazing. Definitely want to see some climbing- but definitely as equally interested in real commercial uses- there's definitely applications in emergency self rescue type stuff- but what about something like picking up a car or a windshield? I love the idea of conveyers/sprag type deals. This is neat stuff. even just as a tape to stick to itself in a strip- in theory it could be used to wrap things, and then be released by a brief pulsed torsional shock.

It is incredibly fascinating that nature somehow figures all this out and utilizes it perfectly

VoltisArt 4 ヶ月前

All those branches in the microscope shot of the gecko pads are very similar to how nature figures things out. In the case of nature, most of the branches don't work, but a few do, resulting in evolution and natural selection. (Multiple sources say about 99% of species go extinct.) A "working" branch doesn't mean the _best_ selection, it just means the one that got to make babies and pass its DNA forward, making at least one more branch. Geckos are a very weird and very cool group of branches.

Makes sense to me. Evolution had quite a long time patch the bugs

Dan 4 ヶ月前

A few problems with the theory of evolution. 1. Gaps in the Fossil Record: The fossil record provides valuable evidence for the history of life on Earth. However, there are gaps in the fossil record where transitional forms between different species or major groups are missing. This has led to questions and debates about the completeness of the fossil record and the extent of transitional fossils. 2. Origin of Complex Structures: The origin of complex structures and organs in organisms, such as the eye or the bacterial flagellum, has been a topic of discussion. Critics argue that the step-by-step evolution of such complex structures through natural selection and gradual modifications may pose challenges. 3. Irreducible Complexity: The concept of irreducible complexity, proposed by biochemist Michael Behe, suggests that certain biological systems are so intricately designed that their components are interdependent, making it unlikely for them to have evolved in a stepwise manner. However, this argument has been challenged by evolutionary biologists who argue that complex structures can evolve through incremental changes, with intermediate stages serving different functions. 4. Origin of Life: The theory of evolution focuses on the diversity and adaptation of life forms once life has originated. The question of how life originated from non-living matter, known as abiogenesis, is a separate field of study. While there are various hypotheses and ongoing research in this area, the exact mechanisms of abiogenesis are still not fully understood. 5. Genetic and Epigenetic Factors: Advances in genetics and epigenetics have provided new insights into the complexity of gene regulation and hereditary mechanisms. Some argue that these factors challenge certain aspects of traditional evolutionary theory, raising questions about the role of non-genetic inheritance, epigenetic modifications, and the interplay between genes and the environment in evolution.

That is so cool. I'd imagine eventually you could culture a big sheet of gecko foot skin cells in a life support medium and just separate sheet after sheet of the keratin(?) they deposit to get the real deal, or replicate the same molecular pathways using enzymes in solution inside like a collagen framework without needing real cells at all. Gecko feet make the stuff just fine, I'm sure before too long we can do whatever they're doing to get it.

I love this (and geckoes and insects with such surfaces under their feet). Incidentally, as well as under their feet, at least some geckoes have such a patch under the original tail (not the regenerated tail after losing the first one, having regrown the lost tail, they simply have to carry the new tail once it has re-grown).

Pop quiz: Do polar N2O and nonpolar CO2 liquids mix under a pressure chamber even though they have similar densities? If not, what would happen when you tried to make both liquids supercritical in the same chamber? If one were to be very rich and irradiate one of the molecules, N2O, with neutrons, would the density of enriched N2O be greater than normal CO2? Just a few thoughts.

Tharxis 7 ヶ月前

I've seen that kinda phenomenon with a certain type of plant that grows in the wild. It's probably got the same structure as the artificial gecko skin. When you brush your finger against its blade, it's going to stick and sting like it's got little sharp edges all along its area, but if you brush along, you don't feel anything. I think it's pretty similar.

Maeve Smith 7 ヶ月前

Those are cool in their own right! They actually use microscopic barb like structures that grow in one direction, so that when you slide your hand or fingers along it in the same direction they grow, it feels slick and smooth with no resistance, but in the opposite direction every one of those barbs is digging in and causing that pain. No Van Der Waals forces to speak of, but it's a really interesting mechanism all the same!

This reminds me of the phone book mythbusters episode where it took two tanks to pull two phone books apart that had their pages interwoven with each other. If I recall, the physics behind that is just simple friction, though I guess it would be the same forces applied here? It's not like the phone book pages were electrostatically charged, so I assume the force holding them together were also Van Der Waal.

I'd love some work gloves with this. As a machinist, holding on to metal parts with normal rubber gloves is incredibly tricky if there's any oil on the part or the gloves. I imagine making this stuff is still incredibly expensive though

V Tushar 7 ヶ月前

Well that wouldnt work prolly if it had oil on the surface cuz it relies on vander walls force i.e. attraction between the atom of the gecko to the atoms at the surface of the hammer. So oil will basically be sliding and it might as well get stuck in between the ridges destroying the gecko tape

Alejandro Escalera 8 ヶ月前

Hello Derek, I have an idea for a video. In chemistry, I learned that in redox reactions, electrons transfer, but it was never quite explained how or why exactly they do it. I would love a video about this process, which I found out is explained using quantum mechanics. That way, I might finally understand how the electrochemical potential table forms and why different organisms are an-/aerobic on a deeper level. If you (not Derek) read this and also wonder how this works, I would appreciate if you could give this comment a push so that Derek sees it. Thanks, keep up the good work, and greetings from Switzerland. Alejandro

The applications for this in the trad climbing community could be great. In trad climbing, gear is placed in cracks and faults in the rock to catch a potential fall, but this isn't really possible currently on flatter surfaces with less cracks for gear placement. With this it could be possible to place gear on a flat surface, let it sit there while the climber climbs, and catch their fall if they do. It would completely open up a whole world of harder trad climbs that haven't been possible due to lack of gear placements for protection.

Would a shoe bottom with this make doing the moonwalk easier? Would it be like flubber for sprints or long jumps? The single direction friction seems like it could make an interesting advantage in sport footwear.

Nicholas P 6 ヶ月前

Hoping someone can shine some light on a question. Ignoring the fact that the gecko skin works in one direction only (being a benefit of the gecko skin), with that being said would the artificial gecko skin if it was made flat (like glass) would it stay permanently fixed to glass once applied since there would be maximum contact between the two surfaces?

I feel like this would be relatively easy to make with the right setup. Even a desktop cnc fitted with an incredibly high quality blade should be able to produce this surface directly on the "part". It would require a lot of custom toolpath work, but that shouldn't be too difficult. Or to make a mold, some sort of thermoplastic could be held at a temperature that keeps it soft for cutting, then cooled to have a more durable surface. Wish I had more time to work on this. It would be a fun project.

Great video Derek! I have a question though, if you mentioned earlier that if you invert the Apple over then the sticky pad let's the Apple go.

I wonder if they could use the Nano 3D printer to make smaller legs on the gecko skin. Supposedly, the printer can create parts around 500 nanometers, though the materials the Karlsruhe Institute are currently printing in may not be viable, it could be worthwhile having both labs work together on the project. Could be a significant improvement on the wax mold method and could be more reliable to 3D print than to use a razor. [edit] If they 3D print the mold, not 3D print with liquid silicone.

@Enorazza Right? I'm so curious how much better is the gecko than the artificial version, considering we seem to be able to fill the same surface area. Is it something like 80% as good, 95% as good? What if it were like half as good as the gecko? Crazy to think of the possibilities were that the case and we just need to iterate on the processes

seasong 8 ヶ月前

Very cool, what materials are you working on now?

Enorazza 8 ヶ月前

@Sean Kane as they say in the video, what they can do is a very raw bad approx of what a gecko can. I would say they do not more than a mere 5-10% (i am being optimistic) and so, the possibilities are HUGE. We need to learn how to build something purely from a DNA.. like a cell does. Crispr is great to modify DNA, but to have a sheet of "gecko foot" made from the Gecko DNA (and then even improving it!) is pure science fiction nowadays. Having this capability will open the "God door" with unimaginable possibilities. We are so so far from that (50 years?)

about 30 years ago I kept a gecko in my house to control the ever-encroaching insect population. I was simply amazed at how the creature would run on walls and ceilings as if gravity simply wasn't a thing. It never had to pull its foot up like it was suction cupped, and it never left any residue behind. I would try to study it whenever I could get close, but it was a mean SOB and would try to bite me. I was completely interested in how the thing worked, so I did some research. Imagine my surprise when I discovered that, at the time, the answer was - no one knows how they work.

Great video Derek! I have a question though, when performing all those heavy tasks like pulling the car, how was the material able to handle those force because the material itself is made up of silicone right? Which I know is tensile, but not that much! So how did it withstand those forces?

Ethan Alexander 8 ヶ月前

I’m guessing that the backing material used provides added structural support. Some polymer films can have tensile strengths of 1,000s+ of psi! (I’ve seen some up to 20,000 psi!) However it’s also worth mentioning that towing a car across smooth flat ground may only require as little as 100 lbs of force since you only need enough force to overcome the initial rolling resistance

@Major Motoko Its not meant to be pulling weight , its real use case is in robotic arms to handle delicate items where weight is not an issue and can not use conventional robotic arms because pressure exerted by conventional arms will damage the delicate items

This is incredible. But I wonder how quickly it accumulates dust/dirt, as these would surely prevent the shear induced vdv force from being large. Eg the guy climbing a building with it, I would be very concerned with deterioration. And what happens to the material when it is wet, or soap added to clean it. Fascinating.

I hope one day this technology is adapted as plasters/medical tape. My newborn requires an NG tube for feeding and we have to tape it to his cheek, but he is allergic to adhesive and we are now in a battle over managing his poor skin degrading. It makes me happy to think how future families in similar situations could benefit from this concept.

I recommend looking for hypoallergenic tape if you haven't already, many people who are sensitive to adhesive find it to be a life saver.

This stuff is super cool. I think in the near future there will be robots climbing buildings faster than a human can run horizontally using this stuff. This needs to be worked on more, I could see this being the future of heavy machinery too.

This seems very similar to how the gloves of mission impossible work, where Ethan scales the glass building. Except where that glove fails if the battery fails, this doesn't. Physics is so cool 😃

Would be cool to make a racecar tire out of this. I guess it would not go in reverse, and it would have to be on a smooth road. But it would have great grip while going forward right? Like a dragster type deal

Looking at the structure of Gecko feet reminds me of the structure of some mushrooms. I wonder if there would be a way to engineer a fungus that would grow in a pattern similar to gecko feet to get the more sophisticated design?

Jraqn 7 ヶ月前

this is very similar to an idea I had for a stem project in elementary school. The project was to come up with an idea for an invention based on some adaptation an animal had and how it could be used in real life applications. My idea was a set of gloves and socks that had the properties of gecko feet, where anyone wearing them could climb any surface. It’s very cool to see that that idea is actually a real thing :)

Well that’s a kinda dumb thing to say especially as a science teacher they were also saying we would never go to the moon, fly, or breathe underwater. I guess that’s why he was a high school teacher and not a professor

Could use a laser CNC router to mass produce those cuts maybe.. imagine placing the cuts on a bendy piece of aluminum or any other bendable metal like Nitinol that would allow the material to bend enough .. you could use it to grab cargo ships. Or latch onto objects in space without having to drill into an asteroid.

They need to make the peeks ring shaped then put a small lever in the middle in the back like conventional suction cups use and just have it life slightly so the suction forces all the peaks flat then it could use the same lever to push a bubble into the middle causing a chain reaction to release. Or use a small new attic bit of suction and pressure in place of the center lever.

Wow i remember when i was younger, my family didn't have cable so i was stuck watching local TV. One of my favorite shows was on PBS kids called Wild Kratts. These 2 guys taught you all about animals but one of my favorites was the Gecko. The guys in this show had Gecko-inspired suits which i always wanted to be real. This is really making my childhood dreams come true

Great Material and great video! What I don't get is: why always use pulling cars around as a benchmark? It's not like a lot of force is needed to move a wheeled object horizontally.

Aysha Munazza 5 ヶ月前

The video was so informative , the se facts never even occurred in my mind before , how simple things in nature work ..................................👍👏👏 Just had a small doubt , gravity also plays a part in this equation like due to gravity the material gets the initial action . in the case where it was used in the space station i understand with the help of a motor the material gets the initial action , but why would it still work when the motor is turned of , floating around the object could go the opposite way . (Are multiple pieces used in particular directions to keep it firm ? )

Also I think it would have been good to see a timelapse of how long dods the tape really hold. I'm pretty sure eventually as enough time passes, there will be small changes and the force energy will change to some other energy form. For example if a gecko is dead, surely it wont be holding on forever.
