Stretchable conductors are a class of electronics characterized by their signifi cant deformability and have emerged as essential

components for the next generation of electronic devices. However, signifi cant conductivity reduction under stretching

poses a limitation for their application across various fi elds. Liquid metals, as conductors possessing both high electrical

conductivity and fl uidity, provide an ideal solution to this challenge, facilitating the development of stretchable conductors

with enhanced electrical stability. The present review, aiming at providing guidance and stimulating research enthusiasm

for future research, delivers a comprehensive overview of the design, fabrication, and applications of liquid metal-based

stretchable conductors (LMSCs). First, the prevalent fabrication methods for constructing LMSCs are presented, followed

by a discussion on the key performances of LMSCs, wherein the principles vital for achieving high electrical stability are

thoroughly discussed. Then, several representative applications of LMSCs are illustrated. Finally, this review makes a brief

discussion on the current challenges and future development of LMSCs.
