Abstract :
Theory and practice for wind generators based on piezoelectric polymers are reviewed. The basic piezoelectric equations are applied to bimorphs set into mechanical oscillation by the wind. The importance of incorporating mechanical and electrical resonance into the design is emphasized. The design and performance of two rotating generators are described, and performance is compared with theory. Design improvements are proposed, and future prospects are evaluated
