Artificial protective skins are widely used in artificial intelligence robots, such as humanoid robots, mobile manipulation robots, and automatic probe robots, but their safety in use, especially flame retardancy, is rarely considered. As many artificial skins are designed for use in flammable or even explosive environments, flammability is a significant concern. Herein, a flame-retardant silk/graphene nanoionotronic (SGNI) skin is developed by using a rationally designed high-throughput electro-blown spinning technique, with a more efficient production efficiency than electrospinning. These flame retardant SGNI skins combine the advantages of nanofibrous and ionotronic materials, and they are sustainable, conductive, highly porous, mechanically robust, highly stretchable, self-adhesive, and humidity- and temperature-sensitive. These merits support the assembly of SGNI skins into a fire alarm system, with real-time alarm (response in 2 s) to mobile phones, clouds, and a central control system. The concept that combines a flame retardant and fire alarm material into an intelligent skin may provide potential solutions toward the design of protective skins for robotics and human–machine interactions.

用于多功能消防和报警的电吹纺丝/石墨烯纳米离子皮肤

人工防护皮肤广泛应用于人工智能机器人，如仿人机器人、移动操控机器人、自动探测机器人等，但其使用安全性，尤其是阻燃性鲜有考虑。由于许多人造皮肤设计用于易燃甚至爆炸性环境，因此易燃性是一个重要问题。在此，采用合理设计的高通量电喷纺丝技术开发了一种阻燃丝/石墨烯纳米离子电子（SGNI）皮肤，其生产效率比静电纺丝更高效。这些阻燃 SGNI 表皮结合了纳米纤维和离子电子材料的优点，它们具有可持续性、导电性、高度多孔性、机械强度、高度可拉伸、自粘、湿度和温度敏感性。这些优点支持将 SGNI 皮肤组装成火灾报警系统，对手机、云和中央控制系统进行实时报警（2 秒响应）。将阻燃剂和火警材料结合到智能皮肤中的概念可能为机器人和人机交互保护皮肤的设计提供潜在的解决方案。
