Computer engineers have created electronic microchips that can repair themselves, restoring conductivity when power is cut by a crack in the chip's body. The self-healing circuits work by being intertwined with microcapsules filled with liquid metal. When a crack to the body of the chip cuts power, the microcapsules also crack, releasing the metal inside and restoring the chip's conductivity. The capsules contain eutectic gallium-indiuma metallic material chosen for its high conductivity and low melting point.
