Underwater glove puts octopus’ abilities on the hand of humans
Humans aren’t naturally equipped to thrive underwater. There are critical times when this becomes a liability. Rescue divers, underwater archeologists, bridge engineers, and salvage crews all use their hands to extract people and objects from water, and some of those removals suffer damage if subjected to an iron grip. Researchers at Virginia Tech working to solve this problem have developed an octopus-inspired glove capable of securely gripping objects underwater. They call it: Octa-glove.
