Abstract

Deformable triboelectric nanogenerators (TENGs) show great promise for wearables and human–machine interfaces, but limited output and friction losses constrain their practical application. Here, we present a highly efficient untethered carbon-based non-contact hybrid nanogenerator that combines triboelectric and electromagnetic (EM) induction to convert biomechanical and ambient EM-waste energy into available electricity while enabling self-powered non-contact sensing. It uses graphite-like powder to capture and transport tribo-charges, and graphite-like textiles as tribo-charge reservoirs and stretchable conductors for EM induction. Notably, the use of recycled cotton fabric as a starting material underscores a sustainable and eco-friendly approach to material sourcing. The synergistic designs significantly enhance triboelectricity output (288 V, ± 1.23 μA, 4 Hz) and extend tribo-charge retention time beyond 10,000 min, achieving EM-induced electrification ( ± 15 V, ± 2.4 μA, 60 Hz). Even in non-contact condition, outputs remain 186.5 V (triboelectricity) and ± 9 V (EM waste) at a 1-mm distance, effectively enabling the powering of electronic devices. To the best of our knowledge, this is the first reported non-contact stretchable nanogenerator that can simultaneously harvest both energy types. Moreover, the performance and tribo-charge retention time are superior to those of reported carbon (graphene, graphene oxide, C₆₀)-functionalized non-contact TENGs. Last, a multiplexing self-powered touchless gesture-sensing system is demonstrated. These advancements hold significant potential for real-world applications, such as energy-efficient wearables for health monitoring, touchless human-machine interfaces in robotics, and sustainable self-powered sensors for environmental monitoring, offering efficient material and structural strategies for hybrid energy harvesting and sensing in next-generation devices.

协同设计的碳基混合非接触摩擦电-电磁纳米发电机，具有超长电荷保留，用于可穿戴和环境电磁废物能量收集和自供电传感

可变形摩擦电纳米发电机（TENGs）在可穿戴设备和人机界面方面显示出巨大的前景，但有限的输出和摩擦损失限制了它们的实际应用。在这里，我们提出了一种高效的无系缚碳基非接触式混合纳米发电机，它结合了摩擦电和电磁（EM）感应，将生物力学和环境EM废物能量转化为可用电能，同时实现自供电非接触式传感。它使用类石墨粉末捕获和传输摩擦电荷，并使用类石墨纺织品作为摩擦电荷储存器和可拉伸导体用于电磁感应。值得注意的是，使用再生棉织物作为起始材料，强调了材料采购的可持续和环保方法。协同设计显著提高摩擦电输出(288 V,± 1.23μA, 4 Hz)和扩展tribo-charge保留时间超出10000 分钟,实现EM-induced电气化( ± 15 V,± 2.4μA, 60 Hz)。即使在非接触状态下，在1mm距离内输出仍保持186.5 V（摩擦电）和± 9 V（电磁损耗），有效地为电子设备供电。据我们所知，这是第一个可以同时收集两种能量的非接触式可拉伸纳米发电机。此外，该材料的性能和摩擦电荷保留时间优于已有报道的碳（石墨烯、氧化石墨烯、C60）功能化的非接触式teng材料。最后，演示了一种多路自供电的非接触式手势传感系统。这些进步在实际应用中具有巨大的潜力，例如用于健康监测的节能可穿戴设备，机器人中的非接触式人机界面，以及用于环境监测的可持续自供电传感器，为下一代设备的混合能量收集和传感提供高效的材料和结构策略。
