Abstract:
1. An aerodynamic vibration power-generation device, comprising: at least a brace; and at least a blade, with at least one side attached to said brace, being an aerodynamic vibration element, having at least a piezoelectric transducer embedded inside said blade with areas of said blade extending directly above and below said piezoelectric transducer; said embedded piezoelectric transducer further having related circuitry electrically connected to a load unit; wherein when airflow passes along two sides of said blade, a difference between air speed on two surfaces of said blade generates a pressure difference, and continuously changing air speed generates a continuous pressure difference to cause said blade to deform and vibrate, which makes said embedded piezoelectric transducer deform and vibrate to generate electric current.
