Figure 6. Reconfigurable circuit welding and transient electronics. (a) Schematic showing the circuit connected to the LEDs spelling ‘SZU’. The liquid metal robot serves as a reconfigurable interconnector. The experiment is done in a petri dish filled with a thin layer of water (Movie S5). (b1-b8) Optical images of the actual circuit. The light is turned on or off by the droplet in the center of the control platform. (c1-c8) Schematic diagrams of the circuit corresponding to the photographs in (b1-b8).
