Triboelectric nanogenerators (TENGs) converting mechanical energy into electrical energy have received much attention because of their huge potential applications for supplying power to electronic devices. Improving the performance of TENGs has become a research hot point because of their output limited current. In this paper, we propose a flexible single-electrode triboelectric nanogenerator based on porous Na₂CO₃/polydimethylsiloxane (PDMS) structure to enhance the triboelectric performance for nanogenerators. To compare their output performance, NaCl and sugar are normally used as sacrificial template for triboelectric nanogenerator. As an experimental result, the nanogenerator based on porous Na₂CO₃/PDMS structure obtains the open-circuit voltage of 125 V and maximum output current of 100 μA, which are higher than that generated by NaCl/PDMS and sugar/PDMS TENGs. And the generated electric energy of Na₂CO₃/PDMS TENG could instantaneously power 42 commercial light-emitting diodes without any energy storage devices. This developed porous Na₂CO₃/PDMS TENG could open a new application field for self-powered personal electronics because of its flexibility, simple manufacturing process, and the ability to harvest mechanical energy from human motions.

基于多孔Na ₂ CO ₃ /聚二甲基硅氧烷薄膜的柔性单电极摩擦电纳米发生器和人体运动传感器

将机械能转换为电能的摩擦电纳米发电机（TENGs）备受关注，因为它们在为电子设备供电方面具有巨大的潜力。由于其输出电流有限，提高TENG的性能已成为研究的热点。在本文中，我们提出了一种基于多孔Na ₂ CO ₃ /聚二甲基硅氧烷（PDMS）结构的柔性单电极摩擦电纳米发电机，以增强纳米发电机的摩擦电性能。为了比较它们的输出性能，通常将NaCl和糖用作摩擦电纳米发电机的牺牲模板。作为实验结果，基于多孔Na ₂ CO ₃的纳米发生器/ PDMS结构获得的开路电压为125 V，最大输出电流为100μA，高于NaCl / PDMS和制糖/ PDMS TENG产生的开路电压。Na ₂ CO ₃ / PDMS TENG产生的电能可以立即为42个商用发光二极管供电，而无需任何储能装置。这种开发的多孔Na ₂ CO ₃ / PDMS TENG由于其灵活性，简单的制造过程以及从人体运动中获取机械能的能力，可以为自供电个人电子设备打开一个新的应用领域。
