With growing interest in artificial intelligence and the Internet of Things, self‐powered electronics have gained considerable attention. In this investigation, a wind‐driven hybrid nanogenerator system comprising a poly( l ‐lactic acid)‐based piezoelectric nanogenerator and a poly(tetrafluoroethylene) electret‐based triboelectric nanogenerator (E‐TENG) is proposed. At a wind speed of 5.1 m s −1 , the open‐circuit voltage ( V oc ) and short‐circuit current ( I sc ) of the hybrid nanogenerator (NG) reach ≈ 140 V and 16 µ A, respectively. The maximum output power of the hybrid NG reaches ≈ 0.49 mW with a matching resistance of 8 M Ω , which is 22% larger than the output power of the E‐TENG. The hybrid NG can charge a lithium battery to 2.9 V in 8 h. Furthermore, the charged battery can be employed to drive an IR remote controlled light‐emitting diode lamp and turn the lamp on and off. In addition, it can be combined with a Bluetooth low energy (BLE) temperature sensor to form a self‐powered BLE temperature detection system. The hybrid NG shows great promise in self‐powered environmental monitoring and detection applications.
