Walking up the side of buildings like Spiderman could soon be a reality, scientists have claimed. Sticky gloves and shoes are being developed using a material that allows the wearing to stick and climb up walls.
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.
Engineers now want to "scale up" the design for humans as part of a project that has been codenamed Z-Man. 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.
