Also: EGaIn, gallium-indium, Galinstan
Some gallium alloys are liquid at room temperature yet conduct like metal, so they can make stretchy wires and soft electronics.
Readiness: lab lab studies · prototype demonstrated objects · commercial products or buildings in real use · review summaries of other studies.
Dickey and colleagues showed eutectic gallium-indium forms a thin skin that lets the liquid hold shapes in tiny channels.
Built / tested: stretchable wires
