Triboelectric nanogenerators (TENGs) typically have very low outputs in terms of root-mean-square (RMS) values as the outputs are in the form of short duration pulses. In order to overcome this limitation, here we introduce multi-phase rotation-type TENGs (MP-TENGs). The rotator of the MP-TENGs consists of alternating components of PTFE and mono cast nylon, whereas the stator consists of PTFE with multiple back electrodes. Each electrode produces an output of the same frequency and amplitude, but of different regularly shifted phases. Consequently, the outputs from all the electrodes are full-wave rectified and superimposed, and the total output of the MP-TENGs is almost constant direct current (DC), unlike typical TENGs, with much higher RMS values. A 5-phase TENG has produced 380 V, 3.6 mA m⁻², and 4.9 W m⁻², and the current crest factor is dramatically decreased to 1.26. Finally, due to the almost constant DC output, the MP-TENGs successfully operate electronic devices and charge a battery.

通过新型非对称设计为摩擦式纳米发电机提供可持续的直流电†

摩擦电纳米发电机（TENG）通常在均方根（RMS）值方面具有非常低的输出，因为输出是以短持续时间脉冲的形式出现的。为了克服此限制，在这里我们介绍多相旋转型TENG（MP-TENG）。MP-TENG的转子由PTFE和单铸尼龙交替组成，而定子由具有多个背面电极的PTFE组成。每个电极产生的输出具有相同的频率和幅度，但具有不同的规则移相。因此，所有电极的输出均经过全波整流和叠加，与典型的TENG不同，MP-TENG的总输出几乎是恒定的直流电（DC），而RMS值要高得多。5相TENG已产生380 V，3.6 mA m ^-2和4.9 W m^-2，并且当前波峰因数急剧降低至1.26。最后，由于DC输出几乎恒定，MP-TENG成功地操作了电子设备并为电池充电。
