Gallium-Based Liquid Metal Flexible Electronics Prepared by Solid–Liquid Phase Transition

A facile fabrication method of pure gallium-based flexible electronics has been developed by using the solid–liquid phase transition at ambient temperature, effectively broadening the application of traditional processing techniques in these stretchable devices. The key point of this work is to make ductile Ga-based liquid metal wires, which exhibit superior mechanical properties with a tensile strength of 30 MPa and a break strain higher than 10
