Abstract

A challenge for self-powered flexible devices with applications in the field of Internet of Things (IoT) is their fast and cost-effective production, ensuring accurate display and recognition of many motion trajectories for intelligent control. Herein we present a fully self-powered triboelectric sensor made via extrusion-based additive manufacturing (AM), efficiently embedding post-purified long silver nanowires (AgNWs) in thermoplastic elastomer (TPU). The deformable AgNW stretchable electrodes make the stress transfer stable throughout the device, to achieve outstanding self-powering properties. The roughness of the surface is enhanced by sandpaper treatment design, which significantly improves triboelectric features with voltage increases from 4.9 to 16.7 V. The extrusion-made composite sensor enables the development of a highly reliable artificial intelligence (AI) driven motion recognition system, with a detection reliability as high as 97%. This accuracy level according to a scalable manufacturing technique offers a promising approach for future IoT devices focused on advanced action interaction and smart wearable electronics.

采用材料挤压技术制造的自供电柔性超长电极传感器，用于人工智能驱动的精确运动识别

在物联网（IoT）领域应用的自供电柔性设备面临的挑战是其快速和经济高效的生产，确保准确显示和识别许多运动轨迹以进行智能控制。在此，我们提出了一种完全自供电的摩擦电传感器，通过基于挤压的增材制造（AM）制成，有效地将纯化后的长银纳米线（AgNWs）嵌入热塑性弹性体（TPU）中。可变形的AgNW可拉伸电极使整个器件的应力传递稳定，实现出色的自供电性能。砂纸处理设计增强了表面的粗糙度，显著改善了摩擦电特性，电压从4.9 V增加到16.7 V。这种挤压制造的复合传感器能够开发出高度可靠的人工智能（AI）驱动的运动识别系统，检测可靠性高达97%。基于可扩展制造技术的这种精度水平为专注于高级动作交互和智能可穿戴电子产品的未来物联网设备提供了一种有前途的方法。
