DESCRIPTION:In the animal kingdom\, adhesion and friction plays a fundamen
 tal role to secure locomotion on a variety of natural surfaces and is ther
 efore of great importance in e.g. ceiling walk\, prey capturing\, and defe
 nce against predators. Previous comparative experimental studies on biolog
 ical systems showed that their attachment organs are a non-trivial combina
 tion of structural (geometrical) features and material properties\, which 
 allow some animals\, such as insects\, spiders\, geckos to adhere to and t
 o walk on vertical walls and ceiling. During the past two decades\, numero
 us studies have been done in order to understand the physical principles u
 nderlying the performance of those attachment systems\, which are\, of cou
 rse\, also very interesting from the biomimetics point of view. In the pre
 sent seminar the functional principles of biological adhesive systems are 
 discussed as well as the recent progress with artificial bio-inspired surf
 aces.
