Scientists Figure Out How To Scale Walls Like Spider-Man
If you’re a big Spider-Man fan, you’re going to love this: A team of researchers at Stanford has developed a way to scale glass walls using pads that attach to a person’s hands.
It’s kind of like the webbed wonder, but a little less slick than this:
The team is part of Stanford’s Biomimetics and Dexterous Manipulation Laboratory, a research group that previously created vertically climbing robots. The inspiration behind the design was not actually Spider-Man, but the gecko, which is able to climb up a variety of surfaces using what are known as van der Waals forces.
To replicate these electric forces, the Stanford team created hexagon-shaped pads about the size of pingpong paddles. They then covered them in tiny tiles made from polydimethylsiloxane — a silicon material commonly found in water-repellant coatings. The material itself isn’t actually sticky like tape or glue.
Like a gecko’s toes, the tiles have tiny nanofibers that make the pads strong enough to cling to glass surfaces. Flexible springs behind the tiles help to distribute the weight.
