![]() It could also snag a delicate, Jell-O-like bead of hydrogel. The glove was able to latch onto a toy car, a spoon and a bowl. This allows wearers to pick items up without even closing their hands.īartlett and his colleagues used the glove to pick up various objects underwater. ![]() Sensors on the glove activate suction at its fingertips whenever it approaches an object. The octopus-inspired suckers on a new wetsuit glove can comfortably pick up varied objects, from a metal toy car to a squishy hydrogel bead. When the sensor nears an object, it switches the sucker on that finger to sticky mode. That causes the sucker to pop off surfaces.Įach finger also has a Tic Tac–sized sensor that detects nearby surfaces. Pumping air into the sucker inflates the cap. Pulling air out of the sucker draws its cap into a bowl shape that sticks to surfaces like a suction cup. That cone is capped with a thin, stretchy rubber sheet. His team described the new glove online July 13 in Science Advances.Įach of the glove’s suckers is a cone of rubber about as big as a raspberry. ![]() He’s a mechanical engineer at Virginia Tech in Blacksburg. could be good for marine biology,” says Michael Bartlett. “Being able to grasp things underwater could be good for search and rescue. These suckers let the wearer grab slick objects underwater without having to squeeze tight. Each of its fingertips is outfitted with a sucker inspired by those on the arms of an octopus. For all its deftness, the human hand is not good at gripping slippery things. ![]()
