The future of Spider-man suit

clipped from news.bbc.co.uk

A “Spider-man” suit that enables its wearer to scale vertical walls like the comic and movie superhero could one day be a reality, according to a study.

Natural technology used by spiders and geckos could help a human climb the side of a building or hang upside down from a roof, the analysis suggests.

Both spiders and geckos possess tiny “hairs” that allow them to stick to surfaces.

Professor Nicola Pugno, from the Polytechnic of Turin, Italy, has calculated how sufficient stickiness could be generated in the same way to support an adult human’s body weight.

The Turin-based researcher proposes that carbon nanotubes could be used as an artificial alternative to the gecko’s hairs.

Firstly, and most obviously, it must be able to demonstrate strong adhesive properties. Secondly, the suit must be able to detach easily from a surface after it has stuck. Thirdly, the suit must, to some degree, be able to clean itself.
