"A Laminated Gravity-Driven Liquid Metal-Doped Hydrogel of Unparalleled" by Qingtian Zhang, Hongda Lu et al.
Conductive hydrogels have been promising candidates for wearable and flexible electronics due to their high flexibility and biocompatibility. However, the previously reported hydrogels with conductivity over 1000 S m−1 usually have poor mechanical properties including low tensile stress (<5 >MPa) and toughness (<2 MJ>m−3). Here, a liquid metal-doped polyvinyl alcohol (PVA-LM) hydrogel is presented, which simultaneously combines ultra-high conductivity (maximum of 217 895 S m−1)...
