Metal melt extrusion in gaseous or vacuum environments is a classical approach for forming wires. However, such extrusions have not been investigated ionic solutions. Here, we use liquid metal (LM) gallium (Ga) and its eutectic alloy with indium (EGaIn) to explore the possibility of electrochemical wires study tuning self-liming oxide layers as coating these formed during process. By controlling surface tension LM immersed an electrolyte, through electrocapillary effect, enable The morphologies thickness are when Ga EGaIn processed neutral basic electrolytes using various voltages. Taking advantage oxides, show that offer tunable composition system investigate related working mechanisms. into patterns automated stage self-healing capability. This work presents unconventional method fabrication wires, offering prospects further research industrial scale-up.
