Abstract
Triboelectric nanogenerators (TENGs) based on the composite of polystyrene (PS) and silver nanowires (Ag-nWs) have been investigated. With open-circuit voltage, short-circuit current and power density of ∼200 V, ∼15 μA and ∼395 mW/m2 respectively in the contact separation mode, these TENGs exhibit highly reliable performance. To harvest the wind energy, a novel hook-shape geometry of the top fluttering electrode is demonstrated which is constructed using light-weight rectangular aluminum foil and is fixed at both ends. With PS:Ag-nW composite film, the hook-shaped-electrode TENG (HSE-TENG) provided an average VOC of 15 V, ISC of 0.75 μA and a power density of 18.33 mW/m2 at a wind speed of 5.5 m/s. Under high outdoor temperature and humidity levels, HSE-TENG demonstrated a high degree of response stability. In addition, the proposed TENG is affixed on the top surface of a moving vehicle, where it has been demonstrated to scavenge the energy from the experienced wind force. This study indicates that material strategies and device design approaches can be amalgamated to achieve high performance and operational robustness together for a specific application regime.
