Thanks so much to Derek and team for visiting our lab! This was a great video on our gecko-inspired adhesives, and the best explanation yet of Van der Waals 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-kp1ie Год назад

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

@VoltisArt Год назад

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.

@wontonschannel 11 месяцев назад

@dan9521 11 месяцев назад

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.

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.

We tend to see scientific and technological advancement as something that is bound to happen and that we are 100% entitled to. Although it's like it's almost impossible to slow its pace down now 'cause many hands are on deck, these things have always been done by people like ourselves and they actually take time. It's just that successful ones are easy to spot than thousand of the unknown, failed procedures leading to successful ones.

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.

I love how the technique they use for manufacturing this stuff is dead simple on a small scale. Their machine is quite large for the precission, so that's definitely where it gets to an impressive level of engineering, but if you wanted a few millimeters of the stuff, sub-micron precission is super easy to obtain at that level with enough gearing! This gives a lot of hope for the availability of this stuff. I'm sure people will also revolutionize the way it's manufactured to increase the effectiveness, but for this method; basically dead easy and awesome!

@owns9414 Год назад

Yes, Derek. I do want to see you climb something using gecko socks. One question, regardless of how strong the grip is, the material it's made of has to be strong enough to with stand the weight of what it's pulling doesn't it? So what are those strips made of that can withstand the weight of a car between just 4 of them?

@MrAlexlarson99 Год назад

Keep in mind the idea that the tape is “pulling” the weight of car is a little misleading. It’s not like the tape needs to hold the weight of a 3000lb sedan. All you need to do to pull a car on flat ground is to overcome the rolling resistance of the car while it is in neutral. For a 3000lbs sedan that might be something like 50-100lbs. This is an amount of force humans can easily provide hence why you’ll see people pushing their car when stuck or out of gas.

@thewhitefalcon8539 Год назад

@Skinflaps_Meatslapper Год назад

You could do the same thing with regular duct tape, since there's not a lot of force involved, but the op provides a valid point. If one were to use this for lifting any meaningful amount of weight, the material will need to be far stronger.

I have been working on similar projects for about a year and a half now mainly to stick things to other things in the pharmaceutical industry, so that we don’t use adhesive. My solution to making the exact copy of a gecko feet is to actually use silicone to mold a negative of actual gecko feet. And then a copy and edit paste until you have a surface that is large enough that you can create a metallic mold. Because there is no solution to making something that small other than nature itself. For example, bacteria have tiny, small little hairs that we could never manufacture, but we could copy it off of a bacteria.
