Sensitivity‐Adjustable Flexible Conductors Based on Liquid Metals via Magnetic Printing

Abstract The ability to shape and pattern conductors has been indispensable for manufacturing functional devices. Herein, a series of patterned liquid metals–based flexible electronics are fabricated via magnetic printing. The combination of highly conductive liquid metals and flexible photosensitive resins endows the as‐prepared devices with excellent electrical and mechanical properties, such as high electric conductivity (8 × 10 ⁴ S m ⁻¹ ), low detection hysteresis, good durability, and environmental stability. What's more, strain‐insensitive flexible electronics can be achieved by designing the structure of liquid metal‐based conductors, and the resistance is only increased 0.13 Ω at 100% strain. Therefore, the as‐prepared liquid metals‐based flexible electronics have promising applications in stretchable conductors.
