Abstract
Nowadays, people are increasingly interested in how to collect clean energy from nature more effectively. As an emerging harvest, triboelectric nanogenerators (TENGs) can collect a wide range of clean energy from nature. However, the energy generated by TENG can not be used directly for driving various miniature electronics. In this study, we have designed a triboelectric nanogenerator for wind energy harvesting, which consists of two simple generator sets. In addition, a power management circuit based on this triboelectric nanogenerator has been designed, which consists of a rectifier section, an electronic switch section, and a filter section. Among them, the most important part is the electronic switch section, and the electronic switch is based on triode characteristics. The experiment shows that the output voltage has been to stabilize at 3.89V when the triboelectric nanogenerator structure is in operation, and it can sustainably drive the LED in a stable working condition.
