New ‘Superglue’ Could Seal the Deal for Stretchable Batteries, Soft Robots

Scientists have begun using a new, quick-drying adhesive to fuse hard-to-bond materials like elastics and hydrogels (cushiony building materials used in everything from medicine to robotics) without having to worry about the bonding agent becoming brittle and breaking or taking a long time to set. The strong, stretchy adhesive, which is made of cyanoacrylate (the main ingredient in Super Glue) plus an organic compound, sets within seconds. This breakthrough benefits scientists building soft robots, electronics, and medical devices, including a stretchable patch that would allow water-soluble drugs to be delivered directly to the body.
