Current passes through a self-healing circuit.

Led by assistant professor Michael Bartlett, the team’s approach replaces rigid materials and soldered wires currently used in consumer electronics with soft electronic composites and tiny electricity-conducting liquid metal droplets. The result is said to be a soft and stretchy circuit that can sustain ‘numerous damage events’ under load without losing conductivity.
