2025年1月16日早上，学院卓越论坛第20期于南岭校区机械材料馆529成功举办。英国诺桑比亚大学Ben Bin Xu教授做了题为“Graphene Oxide Aerogel Metamaterials for Ultra-robust Directional Sensing at Human-machine Interfaces”的学术报告。论坛由学院吴文征教授主持，学院教师和研究生40余人参加了论坛。
报告中，Ben Bin Xu教授讲解了石墨烯气凝胶的近期研究现状，石墨烯气凝胶具有高度有序的微结构和导电网络，因此在为未来的人机界面开发高性能压力传感器方面大有可为。然而，石墨烯气凝胶应用的瓶颈在于其固有的坚硬蜂窝状结构导致应变感应范围有限。通过简单的加热/冷冻后交联策略，在横截面平面上将微结构从蜂窝状重新配置为屈曲结构，首次实现了具有屈曲网络的各向异性交联壳聚糖和还原氧化石墨烯（CCS-rGO）气凝胶超材料。重构后的CCS-rGO气凝胶显示出超弹性和非凡的耐久性。气凝胶超材料传感器经组装和演示后，可用于监测人体运动、控制机器人手，甚至集成到柔性电子键盘中播放音乐。CCS-rGO所具有的功能可为未来的人机界面开辟广阔的应用前景。
