Octopus-Inspired Self-Adaptive Hydrogel Gripper Capable of Manipulating Ultra-Soft Objects.

ABSTRACT: Octopuses, due to their flexible arms, marvelous adaptability, and powerful suckers, are able to effortlessly grasp and disengage various objects in the marine surrounding without causing devastation. However, manipulating delicate objects such as soft and fragile foods underwater require gentle contact and stable adhesion, which poses a serious challenge to now available soft grippers. Inspired by the sucker infundibulum structure and flexible tentacles of octopus, herein we developed a hydraulically actuated hydrogel soft gripper with adaptive maneuverability by coupling multiple hydrogen bond-mediated supramolecular hydrogels and vat polymerization three-dimensional printing, in which hydrogel bionic sucker is composed of a tunable curvature membrane, a negative pressure cavity, and a p
