Multifunctional self-healing liquid metal hydrogel developed for human-computer interaction

Recently, researchers from the Hefei Institutes of Physical Science (HFIPS) of the Chinese Academy of Sciences, led by Prof. Tian Xingyou and Prof. Zhang Xian, along with associate Prof. Yang Yanyu from the College of Materials Science and Engineering at Zhengzhou University, used gallium indium alloy (EGaIn) to initiate the polymerization and serve as flexible fillers to construct liquid metal/polyvinyl alcohol(PVA)/P(AAm-co-SMA) double network hydrogel.
