Different configurations change the adhesive effect of the silicone material, whose surface has been given a mushroom-like structure. The adhesion is best when bent concave (right).

A research team has succeeded in boosting the adhesive effect of a silicone material significantly inspired by the structure of beetle feet. In addition, they found out that the adhesiveness of the structured material changes drastically, if it is bent to varying degrees. Their results could be interesting for the development of tiny robots and gripping devices.
Geckos, spiders and beetles have shown us how to do it: thanks to special adhesive elements on their feet, they can easily run along ceilings or walls...
