Controlling the oxidation and wettability of liquid metal via femtosecond laser for high-resolution flexible electronics.Liquid metal-based electronic devices are attracting increasing attention owing to their excellent flexibility and high conductivity.  Herein, the wettability and adhesion of liquid metal are controlled by combining the stirring method, femtosecond laser microfabrication, and sacrificial layer assistant.  The wetting area is limited to a micro-pattern by a femtosecond laser and sacrificial layer.
