Wind energy harvester using piezoelectric materials

Abstract

Wireless sensor networks play a very important role in environmental monitoring, structural health monitoring, smart city construction, smart grid, and ecological agriculture. The wireless sensor nodes powered by a battery have a limited service life and need periodic maintenance due to the limitation of battery capacity. Fortunately, the development of environmental energy harvesting technology provides an effective way to eliminate the needs and the replacement of the batteries. Among the environmental stray energy, wind energy is rich, almost endless, widely distributed, and clean. Due to the advantages of simple structure, miniaturization, and high power density, wind energy harvesters using piezoelectric materials (PWEHs) have attracted much attention. By the ways of principal exploration, structure design, and performance optimization, great and steady progress has been made in the research of PWEH. This Review is focused on the review of PWEHs. After introducing the basic principle of PWEHs, the structural performance and research status of PWEHs based on different mechanisms, such as a rotating turbine, vortex-induced vibration, flutter, and galloping, are analyzed and summarized. Finally, the development trend of PWEHs has been prospected.

“…[38][39][40] Therefore, making piezoelectric wind energy harvesters based on piezoelectric materials has gained great interest. [41][42][43][44] Kan et al [45] designed a piezoelectric wind energy harvester indirectly excited by magnetic field coupling, which obtained a maximum output power of 4.73 mW at a load resistance of 1000 kΩ and a wind speed of 24 m s À1 . Li et al [46] proposed a piezoelectric hybrid onboard energy harvester to recover wind and vibration energy generated during driving for the self-powering of onboard microsensors.…”

“…These factors severely limit the widespread adoption of wind-energy harvesting. [10] Alternatively, by replacing wind turbines with piezoelectric transducers, [11] piezoelectric effect-based wind-energy harvesters [12,13] demonstrate a promising approach to realizing compact wind turbines with piezoelectric transducers.
