In recent years, triboelectric nanogenerators (TENGs) have grasped considerable attentions as sustainable power sources for next-generation electronics. However, far too rare research has been carried out to simultaneously achieve stretchability and transparency in TENGs. Here, we developed a stretchable and transparent TENG based on a Mxene-AgNWs-Mxene-polyurethane nanofibers (MAMP) electrode which exhibits excellent optoelectronic properties with low sheet resistance of 10.1 Ω/sq at the transmittance of 87.6%. Meanwhile, the as-prepared electrode achieves outstanding stretchability and durability with maximum strain of 180%, as well as 42% resistance variation after 1000 stretch-release cycles at 65% strain, which is attributed to the synergistic effect of reinforcement of nanofiber-based scaffold and the improvement of adhesion between conductive network and elastic matrix by Mxene. Furthermore, the stretchable and transparent MAMP-TENG is employed as energy harvester and motion sensor, producing output voltage of 38 V and current density of 1.67 mA/m² just by hand tapping. The integration of sustainable power source and motion sensor with the attributes of stretchable and transparent in one makes it promising for applications in wearable devices and human-machine systems.

近年来，摩擦电纳米发电机（TENGs）作为下一代电子设备的可持续电源受到了广泛的关注。然而，进行太少的研究却无法同时实现TENG的拉伸性和透明性。在这里，我们开发了一种基于Mgene-AgNWs-Mxene-聚氨酯纳米纤维（MAMP）电极的可拉伸透明TENG，该电极具有出色的光电性能，在87.6％的透射率下具有低的10.1Ω/ sq薄层电阻。同时，所制备的电极具有出色的可拉伸性和耐久性，最大应变为180％，在65％应变下经过1000次拉伸释放循环后电阻变化为42％，这归因于增强纳米纤维基支架的协同效应以及Mxene改善了导电网络与弹性基体之间的附着力。此外，可拉伸且透明的MAMP-TENG被用作能量采集器和运动传感器，产生38 V的输出电压和1.67 mA / m的电流密度²只需用手敲击。可持续电源和运动传感器的集成具有可伸缩和透明的特性，使其在可穿戴设备和人机系统中的应用前景广阔。
