Versatile Liquid Metal Composite Inks for Printable, Durable, and Ultra‐Stretchable Electronics (Small 41/2025)

Ultra-Stretchable Electronics A printable, self-sintering liquid metal composite ink enables the fabrication of ultra-stretchable and durable electrodes on flexible substrates. Through ambient-condition deposition, the ink forms crack-free, conductive patterns without post-processing. Demonstrated as stretchable metamaterial absorbers, these structures exhibit tunable electromagnetic responses via mechanical deformation, offering a scalable route toward next-generation wearable and reconfigurable electronics.
