Abstract
In this paper, an efficient wind energy harvester (WEH) which simultaneously possesses both the advantages of simple structure and easy manufacture is designed. Proved by the simulation results, the WEH with air outlet at the top side not only effectively increases the rotational speed of the turbine but also obviously enhances the rotation stability of the blades, which eventually turn to improve the output performance of the device. According to experimental analysis, when the wind speed is 15 m/s, the proposed WEH can generate maximum output power of 40.7 mW, with corresponding power density of 0.3 mW/cm3. Last but not least, integrated with a switch-controlled circuit module and a low-powered angle sensor module, a self-powered wireless sensor node (WSN) is successfully established.
