CONVERTISSEUR D'UNE VARIATION D'ENERGIE A RECUPERER EN UNE DIFFERENCE DE POTENTIELS

摘要

The invention relates to a converter comprising a first transducer that can lengthen inside at least a first deformation zone and simultaneously shrink inside at least a different second deformation zone. Inner faces of second and third electromechanical transducers (42-45) are secured respectively, with no degree of freedom, essentially to the first and second deformation zones of the layer of the first transducer. The third transducer differs from the second transducer by the polarisation of its layer (54) of piezoelectric material in a different direction to the polarisation of the layer of piezoelectric material of the second transducer and/or by the existence of a separation that mechanically and electrically insulates a first electrode of the third transducer from a first electrode of the second transducer located on the same side of the layer of piezoelectric material.
