Human-machine interfaces (HMIs) enable users to interact with machines, thus playing a significant role in artificial intelligence, virtual reality, and the metaverse. Conventional HMIs are based on bulky and rigid electronic devices, seriously limiting their ductility, damage reconfiguration, and multifunctionality. In terms of replacing conventional HMIs, artificial bionic skins with good ductility, self-reparation, and multisensory ability are promising candidates. Still, they in their present form require innovations in mechanical and sensory properties, especially damage recovery and environmental stability, which seriously affect the service life and result in tons of electric waste. Herein, we present a new type of artificial bionic skin with excellent mechanical performance (>13,000% strain), high environmental stability (-80 to 80 °C), and multiple sensory properties toward strain, stress, temperature, solvent, and bioelectricity. Besides, this new type of artificial bionic skin also exhibits effective reconfiguration ability after damage and recyclability. The as-prepared artificial bionic skin was used as an interactive HMI to collect and distinguish the different sensory stimuli. The electronics assembled by HMI with artificial bionic skin can adhere compliantly on the human body for wireless motion capturing and sensing via Bluetooth, Wi-Fi, and the Internet. With simple programming, complex human motions can be mimicked in real-time by robots.
人机界面（HMIs）使用户能够与机器进行交互，从而在人工智能、虚拟现实和元宇宙中发挥重要作用。传统的人机界面基于笨重且刚性的电子设备，严重限制了它们的延展性、损伤重构能力和多功能性。就取代传统人机界面而言，具有良好延展性、自我修复能力和多感官能力的人工仿生皮肤是很有前景的选择。然而，它们目前的形式需要在机械和感官特性方面进行创新，特别是损伤恢复和环境稳定性，这严重影响了使用寿命并导致大量电子废物。在此，我们展示了一种新型的人工仿生皮肤，它具有优异的机械性能（应变>13000%）、高环境稳定性（-80至80°C）以及对应变、应力、温度、溶剂和生物电的多种感官特性。此外，这种新型人工仿生皮肤在损伤后还表现出有效的重构能力和可回收性。所制备的人工仿生皮肤被用作交互式人机界面，以收集和区分不同的感官刺激。由人机界面与人工仿生皮肤组装而成的电子设备可以柔顺地附着在人体上，通过蓝牙、Wi-Fi和互联网进行无线运动捕捉和传感。通过简单的编程，机器人可以实时模仿复杂的人类动作。
