Scaling buildings like Spiderman could be a reality, scientists claim

They have already created a new textile inspired by geckos which has been
tested successfully on a small robot that can scale smooth surfaces such as
glass and metal.

Technicians have struggled over the last 10 years to create an artificial
version strong enough for a vertical climb to be attempted successfully.
However, researchers at Stanford University, California, have created a
rubber-like material covered with thousands of tiny polymer fibres to
imitate the gecko’s hairs. These hairs, which are called setae, are ten
times thinner than a human hair.

Geckos’ ability to defy gravity is due to microscopic hairs on their toes,
increasing the surface area, which creates a “one-way adhesive”. A
sticky bond is created with each step but that bond can be broken by
movement in the other direction.

Scientists are now on the way to making a version of the material that “would
allow humans to climb with gecko adhesive.”
