CGTN China’s first adaptive hydrogel suction cup mimics octopus for underwater precision

Researchers at the Lanzhou Institute of Chemical Physics in Lanzhou, northwest China’s Gansu Province, have developed China’s first adaptive hydrogel suction cup, drawing inspiration from octopus tentacles. The device uses a specially designed supermolecular hydrogel and micro-channels to achieve gentle yet firm underwater gripping and precise manipulation. This breakthrough addresses challenges in handling delicate objects in complex environments and is expected to advance fields such as deep-sea exploration, advanced manufacturing, and medical robotics.
