Triboelectric nanogenerator (TENG) as a promising energy harvesting technology attracts much attention in recent years. Among others, the contact mode TENG is often given priority by virtue of its reliable robustness and high energy conversion efficiency. However, in most cases, the contact-mode TENG is only suitable for collecting energy from pressure-induced incentives because it requires a compression forces to drive. Here, we propose a rhombic-shaped paper-based triboelectric nanogenerator (RP-TENG) that may operate effectively under tensile conditions together with an enhanced contact force between the tribo-pair induced by the design of pressurizing braces. Mechanical tests were carried out to investigate the output performance of the RP-TENG under the activation of various applied forces. An integrated RP-TENG with four tribo-pairs were fabricated for optimizing the output performance. The novel design facilitates the device to achieve higher energy conversion efficiency and also expand its application circumstances. A theoretical model is developed to establish the correlation between the output voltage of the RP-TENG and the geometric characteristics as well as external excitations. The results suggest an effective strategy of using paper-based rhombic-shape design to enhance contact-mode TENGs and may serve as a guideline for structural and circuit design of this novel TENG devices.

摩擦电纳米发电机（TENG）作为一种有前途的能量收集技术在最近几年引起了很多关注。其中，接触模式TENG经常因其可靠的耐用性和高的能量转换效率而被优先考虑。但是，在大多数情况下，接触模式TENG仅适合于从压力引起的激励中收集能量，因为它需要压缩力来驱动。在这里，我们提出一种菱形的纸基摩擦纳米发电机（RP-TENG），该发电机可以在拉伸条件下有效运行，并且由于压力支撑的设计而在摩擦对之间产生了增强的接触力。进行了机械测试以研究RP-TENG在各种作用力作用下的输出性能。制造了具有四个摩擦对的集成RP-TENG，以优化输出性能。新颖的设计有利于该器件实现更高的能量转换效率，并扩展了其应用环境。建立了理论模型以建立RP-TENG的输出电压与几何特性以及外部激励之间的相关性。结果表明使用纸质菱形设计来增强接触式TENG的有效策略，并且可以作为这种新型TENG器件的结构和电路设计的指南。建立了理论模型以建立RP-TENG的输出电压与几何特性以及外部激励之间的相关性。结果表明使用纸质菱形设计来增强接触式TENG的有效策略，并且可以作为这种新型TENG器件的结构和电路设计的指南。建立了理论模型以建立RP-TENG的输出电压与几何特性以及外部激励之间的相关性。结果表明使用纸质菱形设计来增强接触式TENG的有效策略，并且可以作为这种新型TENG器件的结构和电路设计的指南。
