Abstract
It is meaningful to research the Triboelectric Nanogenerators (TENG), which can create electricity anywhere and anytime. There are many researches on the structures and materials of TENG to explain the phenomenon that the maximum voltage is stable and the current is increasing. The output voltage of the TENG is high about 180–400 V, and the output current is small about 39 μA, which the electronic devices directly integration of TENG with Li-ion batteries will result in huge energy loss due to the ultrahigh TENG impedance. A novel interface circuit with the high-voltage buck regulator for TENG is introduced firstly in this paper. The interface circuit can transfer the output signal of the TENG into the signal fit to a lithium ion battery. Through the circuit of the buck regulator, the average output voltage is about 4.0 V and the average output current is about 1.12 mA. Further, the reliability and availability for the lithium ion battery and the circuit are discussed. The interface circuit is simulated using the Cadence software and verified through PCB experiment. The buck regulator can achieve 75% efficiency for the High-Voltage TENG. This will lead to a research hot and industrialization applications.

Summary
There are three modes of the TENG: Vertical Contact-Separation mode, In-plane Sliding mode, and Rotation Mode[9]. The maximum output voltage is about 300 V and the output current is low to about 80 μ A17,18. The maximum output voltage is about 400 V and the output current is about 50 μ A19,20. The maximum output power is about 8 mW. The output voltage of TENG is very high, which is easy to destroy some electronic devices, most notably CMOS-integrated circuits and some MOSFET transistors. The lithium ion battery is chosen to store the power of the TENG, whose nominal voltage is 3.6 V23. The lithium ion battery, without overcharging protection, maybe caused an explosion when is overcharged
