Fig. S8 Restoration of a damaged circuit. (a) Schematic diagram showing the process of the liquid metal soft robot reaching the damaged part and repairing it. (b) Optical image during the actuation and repairing operation: (b1) shows the deployment of the droplet, (b2-b5) show movement of the droplet to the damaged part of the circuit, (b6 and b8) show further deployment of liquid metal robots. (b7 and b9) Actuation of the additional droplets to the damaged circuit. (b10) Repaired circuit and (b11) magnification of the repaired part of the circuit. Light up of the LED signifies a closed circuit.
