EXPERIMENTAL STUDY OF AN OMNI-DIRECTIONAL WIND FLUTTERING ENERGY HARVESTER

Wind energy harvesters based on fluttering are a valuable and efficient alternative to traditional wind turbines. The optimized drive trains of traditional wind turbines have significantly shorter life expectancy and higher fabrication costs compared to harvesting systems based on fluttering. This article presents an analysis of a novel windbelt type energy harvester designed to harvest low-speed and changing direction winds. This experimental study explores the optimal ribbon tension, length and coil position of the wind-to-vibration converter, to obtain the maximum vibration acceleration.
