Triboelectric nanogenerators with the function of harvesting human motion energy have attracted wide attention. Here, we demonstrate a shared-electrode and nested-tube structure triboelectric nanogenerator (SNTN) for harvesting human motion energy. The design of the SNTN employs flexible silicone rubber as the negative friction material and Ni-coated polyester conductive textile as the positive friction material and the electrode material. The entire structure consists of an inner triboelectric unit and an outer triboelectric unit. The inner triboelectric unit is formed by a hollow inner tube and a hollow middle tube, while the hollow middle tube and a hollow outer tube constitute the outer triboelectric unit. The hollow middle tube is used as the shared tube, and the electrode in the middle tube is used as the shared electrode of the two triboelectric units. Our research demonstrates that the output performance of the SNTN was improved significantly compared with a single triboelectric unit due to the cooperation of the two triboelectric units. When the SNTN is pressed by 300 N external force, output open-circuit voltage of 180 V and output short-circuit current of 8.5 μA can be obtained. The output electrical energy can light up 31 light-emitting diodes (LEDs) connected serially (displaying "XZTC") and can drive a digital clock after rectifying storage, which shows application prospects in the field of illuminating devices and portable electronics.
具有收集人体运动能量功能的摩擦纳米发电机引起了广泛关注。在此，我们展示了一种用于收集人体运动能量的共电极嵌套管式摩擦纳米发电机（SNTN）。SNTN的设计采用柔性硅橡胶作为负摩擦材料，镀镍聚酯导电织物作为正摩擦材料和电极材料。整个结构由一个内部摩擦电单元和一个外部摩擦电单元组成。内部摩擦电单元由空心内管和空心中间管组成，而空心中间管和空心外管构成外部摩擦电单元。空心中间管用作共享管，中间管中的电极用作两个摩擦电单元的共享电极。我们的研究表明，由于两个摩擦电单元的协同作用，SNTN的输出性能与单个摩擦电单元相比有显著提高。当SNTN受到300 N的外力挤压时，可获得180 V的输出开路电压和8.5 μA的输出短路电流。输出电能可点亮31个串联连接的发光二极管（显示“XZTC”），并在经过整流存储后驱动一个数字时钟，这表明其在照明设备和便携式电子产品领域具有应用前景。
