By utilizing the wind-induced resonance vibration of a fluorinated ethylene-propylene film between two aluminum foils, the integrated TENGs with dimensions of 2.5 cm × 2.5 cm × 22 cm deliver an output voltage up to 100 V, an output current of 1.6 μA, and a corresponding output power of 0.16 mW under an external load of 100 MΩ, which can be used to directly light up tens of commercial light-emitting diodes. Furthermore, a self-powered wind vector sensor system has been developed based on the rationally designed TENGs, which is capable of detecting the wind direction and speed with a sensitivity of 0.09 μA/(m/s). This work greatly expands the applicability of TENGs as power sources for self-sustained electronics and also self-powered sensor systems for ambient wind detection.entriboelectric nanogenerator; wind energy; self-powered; vector sensor; wind sensor; GENERATOR; ELECTRONICS[SDGs]SDG7journal article10.1021/nn4043157240446522-s2.0-84887009033WOS:000326209100120https://api.elsevier.com/content/abstract/scopus_id/84887009033
