A diagram illustrating how the self-healing circuit works
Scientists are creating self-healing electronics, that use liquid metal to instantly restore conductivity to cracked circuits
A hard material is impregnated with microcapsules that burst when the material cracks, releasing a stored liquid that hardens on contact with the air, thus repairing the crack ... it’s a system that we’ve recently seen used in a number of applications, including self-healing concrete and polymers. Now, a research team from the University of Illinois is applying it to electronics. They have already created a system that automatically restores conductivity to a cracked circuit in just a fraction of a second.
