Soft and stretchable conductors with high electrical conductivity and tissue-like mechanical properties are crucial for both on-skin and implantable electronic devices. Liquid metal-based conductors hold great promise due to their metallic conductivity and minimal stiffness. However, the surface oxidation of liquid metal particles in polymeric matrices poses a challenge in forming a continuous pathway for highly conductive elastic composites. Researchers at the Pennsylvania State University reported a printable composite material based on liquid metal and conducting polymer that undergoes a self-assembly process, achieving high conductivity in the bottom surface while maintaining an insulated top surface, high stretchability, and a modulus akin to human skin tissue. They applied the material to fabricate skin-interfaced strain sensors and electromyogram sensors through 3D printing… read more. Open Access TECHNICAL ARTICLEÂ
