UCSD 3D Prints Self-Healing Devices

A team of engineers at the University of California San Diego have developed a new technology that allows certain items to heal themselves after being cut. A specially formulated ink resulted in 3D printed devices that, when cut into pieces, heal themselves thanks to the magnetic attraction between the pieces, which draws them back together into one component. Potential applications include batteries, electrochemical sensors and wearable, textile-based electrical circuits, which the researchers printed and then tested by cutting them and pulling them apart in wider and wider gaps. Each time, the devices healed themselves. Even when the team damaged them up to nine times in the same location, or in four different locations at once, the devices healed and regained their function, losing only a minimal amount of conductivity.
