Intelligent human–machine interfaces (HMIs) integrated wearable electronics are essential to promote the Internet of Things (IoT). Herein, a curcumin‐assisted electroless deposition technology is developed for the first time to achieve stretchable strain sensing yarns (SSSYs) with high conductivity (0.2 Ω cm⁻¹) and ultralight weight (1.5 mg cm⁻¹). The isotropically deposited structural yarns can bear high uniaxial elongation (>>1100%) and still retain low resistivity after 5000 continuous stretching–releasing cycles under 50% strain. Apart from the high flexibility enabled by helical loaded structure, a precise strain sensing function can be facilitated under external forces with metal‐coated conductive layers. Based on the mechanics analysis, the strain sensing responses are scaled with the dependences on structural variables and show good agreements with the experimental results. The application of interfacial enhanced yarns as wearable logic HMIs to remotely control the robotic hand and manipulate the color switching of light on the basis of gesture recognition is demonstrated. It is hoped that the SSSYs strategy can shed an extra light in future HMIs development and incoming IoT and artificial intelligence technologies.

姜黄素辅助 ELD 超弹性纱线用于可穿戴人机界面纺织品

智能人机界面（HMI）集成可穿戴电子产品对于推动物联网（IoT）至关重要。在此，首次开发了姜黄素辅助化学沉积技术，以实现具有高电导率（0.2 Ω cm ^-1）和超轻重量（1.5 mg cm ^-1）的可拉伸应变传感纱线（SSSY）。各向同性沉积的结构纱可以承受高单轴伸长率（>>1100%），并且在50%应变下连续拉伸-释放循环5000次后仍保持低电阻率。除了螺旋加载结构带来的高灵活性之外，金属涂层导电层还可以在外力作用下实现精确的应变传感功能。基于力学分析，应变传感响应与结构变量的依赖性成比例，并且与实验结果表现出良好的一致性。演示了界面增强纱线作为可穿戴逻辑HMI的应用，以远程控制机械手并基于手势识别操纵光的颜色切换。希望 SSSY 战略能够为未来的 HMI 开发以及即将到来的物联网和人工智能技术提供额外的启示。
