Given the intensifying scarcity of non-renewable energy sources,wind power is garnering importance across various fields.However,the prevalent wind power generation technologies have different problems,such as small output and low conversion effiiciency.Hence,in this study,we propose a high-performance hybrid wind energy generator with a bidirectional acceleration structure.Based on a reversing gear,the magnet-coil rotor pair moves in a circular motion at equal speeds and in opposite directions,resulting in twice the output performance of a conventional generator and improving the conversion efficiency up to 38.4％.The optimized wind turbine structure and the soft contact of the triboelectric material allow the generator to start functioning at low wind speeds of 3 m/s.Simultaneously,it can detect wind speeds ranging from 3 to 15 m/s with a linearity of up to 0.997.At a wind speed of 6 m/s,the generator's output power reaches 165.76 mW,which can transmit the data of the light sensor to a computer via Bluetooth for real-time display and also power small electronic devices such as thermo-hygrometers,which demonstrates a wide range of applications in the field of sustainable monitoring.
