Highly Reliable Liquid Metal–Solid Metal Contacts with a Corrugated Single‐Walled Carbon Nanotube Diffusion Barrier for Stretchable Electronics

Liquid metals (LMs) are a special case of metals that exist in a liquid at room temperature, making them one of the most attractive conductive materials in stretchable electronics. In many cases, however, the LM attacks other metals in contact with the LM through penetration, embrittlement, and alloying. To address these critical issues, there have been efforts to introduce robust barriers, which can preserve the underlying metals without...
