Abstract
Official abstract text for this publication.
The present invention relates to a piezoelectric device of a multi-layered structure on which first electrodes and second electrodes are sequentially stacked on a piezoelectric polymer and single surfaces or both surfaces of piezoelectric polymer. In accordance with the present invention, the vibration response characteristics of the piezoelectric polymer can be improved by using the graphene or the composite thereof as a surface electrode material to the piezoelectric polymer; and, there are effects that the response characteristics of the piezoelectric device are excellent and the reliability thereof is excellent by forming a second electrode having an excellent conductivity and a protection electrode thereof.
