Wind-induced vibration piezoelectric energy collection in ventilation tunnels

Ventilation tunnel wind-induced vibration piezoelectric energy collection MFC as in the ventilation and stores it storage device to provide electrical required by wireless sensor tunnel. According effect of materials, instantaneous accumulated positive negative charges generated at both ends vibrator wind speed are collected. By establishing a model, irregular transient captured stored Available direct current. The harvesting model uses rotation traction force drive vibrate, thereby converting into energy, using store device. Experiments verify that when is 8m/s, maximum output voltage 42.2V, which can meet power supply requirements sensors
