Abstract：Aiming at the problems of high starting speed and low output performance of traditional self-powered sensing devic-es for harvesting wind energy,a self-powered sensing device engineered is proposed for low start-up wind speeds.This device not only supplies power to sensors but also detects wind speed in the natural environment.Utilizing the bidirectional rotation structure,the device successfully achieves a low wind speed start-up of 3 m/s,and the output power reaches 23.2 mW when the wind speed is 5 m/s,which can supply power to the temperature and humidity sensor and display it in real time on the computer.At the same time,the output signal of the triboelectric sensing unit is transmitted to the data terminal to display the wind speed in real time.The test results show that the harvester has high output performance and good wind speed detection sensitivity,and it shows good appli-cation prospects in the field of sustainable monitoring of the Internet of Things.
