A piezoelectricity composite material is provided to prevent the rupture of the polymer conductor membrane due to the deformation of polymer and vibration. A piezoelectricity composite material comprises the piezoelectric material layer(110) consisting of the material having piezoelectric characteristic; the conductive layer(120) in which the carbon nanotube and the conductive polymer are mixed. The conductive layer may includes metal nano-particles or other functional polymer. The conductive layer is formed on at least one side of the piezoelectric material layer. |
