Harvesting Wind Energy

Abstract

Wind energy is a very common mechanical energy in nature. Harvesting wind energy has been an important approach for large scale power supply. The traditional method is to use the turbine driven electromagnetic generator. In this chapter, we present some new approaches for harvesting wind energy using TENGs. Two typical rotational structure TENGs have been introduced based on the lateral sliding mode. The flutter-driven structure TENG based on contact-separation mode as driven by the turbulence from air flow is presented. These researches broaden the applications of TENG towards self-powered wind-driven systems in the wild environments.
