We investigated the importance of architectural asymmetry to improve the output voltage of the triboelectric nanogenerators (TENGs) with polyester/spandex blend 3D spacer fabrics. Different types of TENGs were fabricated by stacking the 3D spacer fabrics, polydimethylsiloxane (PDMS) films, and electrodes with different stack configurations. The 3D spacer fabric TENGs fabricated with higher architectural asymmetry exhibited higher output voltages than those fabricated with lower architectural asymmetry. In particular, the TENG with the PDMS/fabric/fabric configuration exhibited the highest maximum peak-to-peak output voltage among all types. The prominent increase in the TENG output voltage was ascribed to the relatively high architectural asymmetry in the device configuration and the relatively high effective density of triboelectric charges.

我们研究了结构不对称对于提高摩擦纳米发电机 (TENG) 与聚酯/氨纶混纺 3D 间隔织物的输出电压的重要性。通过堆叠 3D 间隔织物、聚二甲基硅氧烷 (PDMS) 薄膜和具有不同堆叠配置的电极来制造不同类型的 TENG。与具有较低结构不对称性的 3D 间隔织物 TENG 相比，具有较高结构不对称性的 3D 间隔织物 TENG 显示出更高的输出电压。特别是，具有 PDMS/织物/织物配置的 TENG 在所有类型中表现出最高的最大峰峰值输出电压。TENG 输出电压的显着增加归因于器件配置中相对较高的结构不对称性和相对较高的摩擦电荷有效密度。
