With the fast development of modern industry, energy shortage has become an important problem that restricts the further development of the human society. Conventional wind harvesters based on the electromagnetic effect have been created as one of the most important ways for harvesting wind energy. Recently, TENGs based on the cooperation of the triboelectric effect and the electrostatic induction have been used to harvest wind energy. Figure 2.25 shows the comparison between two wind harvesters, focusing on the mechanism, characteristics, and disadvantages [78]. Compared to conventional wind harvesters, TENGs can be considered as current sources with a large internal resistance, leading to characteristics of high voltage and low current. In addition, WD‐TENGs possess many advantages such as low cost, high efficiency, and easy fabrication, providing them the potential to be utilized as self‐powered electronics.
