Octopus suckers inspire new water-resistant adhesive patch

The suckers of an octopus have inspired the creation of a new adhesive patch that can stick to wet and dry surfaces. After studying the anatomy of an octopus' tentacle, the scientists made a patch created from flexible sheets of rubber covered in artificial suction cups. The sticky patches could one day be used to create wound dressings that can easily be taken on and off and may even inspire a generation of Spiderman-style robots that can scale walls, according to researchers. After studying the anatomy of an octopus' tentacle, the scientists made a patch created from flexible sheets of rubber covered in tiny holes. To create the adhesive, the scientists concentrated on recreating a dome-shaped bulge found at the bottom of the octopus' suction patch.
