Abstract

The machine uses a flowing medium, e.g. air to convert energy directly into electrical energy by the piezoelectric effect via two piezoelectric slabs. These are made of polyvinylfluoride and laid one on the other and are connected together. As the arrangement, so formed, bends, one slab stretches and generates a voltage in one direction, and a slab that contracts and generates a voltage of opposite polarity, such that when the arrangement is exposed to the flowing medium and is made to vibrate, electrical energy can be obtained.

Description

WindbaumWind tree

bekannt ist die Nutzung der windenergie durch rotierende Wandler ( Propeller, Windräder u.ä ) an die ein elektrischer Generator angeschlossen wird.The use of wind energy by rotating converters is known ( Propellers, wind turbines, etc.) to which an electric generator is connected.

Nachteilig ist der mechanische Aufwand für die drehenden Teile und daß das Landschaftbild beeinflußt wird.The mechanical effort for the rotating parts and is disadvantageous that the landscape is influenced.

Erfindungsgemäß soll dieser nachteil vermieden werden, indem die Windenergie durch blätterähnliche,piezoelektrisch arbeitende Wandler aus neuartigen Kunststoffen genutzt wird.According to the invention, this disadvantage is to be avoided by the wind energy through sheet-like, piezoelectrically working transducers made of novel plastics is being used.
