ABSTRACT

Gallium-based liquid metals have received widespread attention in the scientific community over the past few years due to their good fluidity, high electrical conductivity and low toxicity, especially for applications of stretchable and wearable electronic devices. At the same time, electronic devices have ever smaller and smaller volumes, their increasing density places higher demands on conductive patterns design. Thus, more advanced ways to manufacture liquid metal nano/micro structures are needed to meet the superior performance of electronic devices. The main reason that gallium-based liquid metal can be patterned is that a stable oxide thin film can be formed on the interface of liquid metal, which changes the rheological and wettability of liquid metal. Due to this oxide film, liquid metal can be fabricated into nano-/ micro-structures via different processing methods including casting, printing and sintering. This review discusses various methods for processing gallium-based liquid metal alloys and their merits, as well as typical applications of this related field of research.
