Octopus-inspired adhesive skins for intelligent and rapidly switchable underwater adhesion.

The article discusses bio-inspired nervous system detects objects and couples controllable adhesives with intricately embedded sensing, processing, and control to manipulate underwater objects and autonomously triggers the switchable adhesives. Topics discussed include fabrication and characterization of switchable adhesive, the compliance of the adhesive elements through stalk shape variation by changing the stalk angle, and efficiency of switchable adhesion under nonideal conditions.
