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.

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 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.

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.

@andrewgraham821 Před měsícem
Have just come across this site - excellent. As an industrial minerals specialist (geochemistry background) I have worked with a lot of clay minerals. Clays minerals are extremely fine grained and have a huge surface area compared to their thickness and exhibit Van der Waal forces. It is one of the reasons they can have an irreducible water content (can wet them but not fully dry them out) because the water molecules get "locked" onto the clay surface via Van der Waal forces. Aside from intense heat there have been some interesting technologies based on applying a small electrical current / pulse to disrupt the Van der Waal forces and enable water to be driven off the surface. Be interesting to see whether you could flatten out the saw tooth pattern by using an electrical pulse and reverse the same way?

@VoltisArt Před 9 měsíci
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.

@dan9521 Před 9 měsíci
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.

Greatly appreciated
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

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 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.

@dnmurphy48 Před rokem
That is so sad. Is there no hypoallogenic adhesive that could help?
@descai10 Před rokem
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.
Try Hypoallergenic band aid

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

What if you use it for tires will they be more grippy and safe or will the just not be able to move
@DeusExNihilo Před rokem
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
@vtushar6597 Před rokem
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
@vishwadewan8546 Před 9 měsíci
If it gets dirty then its holes will gets filled and it won't work? How to clean it if its holes got filled with something like clay?
@sharifsharifzadeh Před 9 měsíci
Amazing! Have you tried it on your skin? I'm curious.
@theZ3r0CooL Před rokem
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.

@tharxis3803 Před rokem
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.
@maevesmith948 Před rokem
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!

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.
@darwinlim4837 Před rokem
Does this resemble surface tension? Since liquid tries to fill those gap creating full contact to the object. Also liquid doesn't have strong physical formation like solid that's why it doesn't hold that much.
@itaylori Před rokem
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.

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

@@fvictor77 My teacher was a woman and she has a PhD in Biology and Physics. She's definitely smarter than you because, if you read this correctly, you'd understand her point is exactly the same as the professor in the video, and you also would have noticed I referred to her as a woman, not a man. What a way to make a fool of yourself for everyone who can read this.

@@DarkAngelEU oh she’s a woman. My bad not tryna trigger y’all. But why was she a high school teacher… spend all that on a PHD that obviously means she’s not that great. not claiming to be smarter just that a real scientist would ever call something like that impossible. We’re just not there yet. Did you have a crush on her?

I watched this video for a school exam assignment. I found it very interesting to see what the researchers have achieved after studying geckos and how this can be turned into a kind of tape that can carry a lot of things or even a robot that can pull a car.
