A hybrid‐fiber nanogenerator comprising a ZnO nanowire array, PVDF polymer and two electrodes is presented. Depending on the bending or spreading action of the human arm, at an angle of ∼90°, the hybrid fiber reaches electrical outputs of ∼0.1 V and ∼10 nA cm −2 . The unique structure of the hybrid fiber may inspire future research in wearable energy‐harvesting technology.
