Gallium steered on laser-induced graphene: circuits that change their shape and their logic.
Programmable continuous electrowetting tunes the electrochemical potential of a gallium-based liquid metal on demand. Under a fixed external field, the metal moves in a direction set by that potential, on a substrate patterned with laser-induced graphene — conductive, and non-wetting to the metal.
Valves that open and close on demand, size-dependent droplet sorting, feedback sensing, self-healing interconnects, fluidic logic gates.
