A method for promoting an electric output of a piezoelectric/conductive hybrid polymer is provided. The method includes forming a piezoelectric/conductive hybrid polymer by mixing poly(vinylidene fluoride-trifluoroethylene) (PVDF-TrFE) and poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) so as to increase an output current and an output power of the piezoelectric/conductive hybrid polymer; and changing a surface structure of the piezoelectric/conductive hybrid polymer by a nano-imprint process for promoting a piezoelectricity of the piezoelectric/conductive hybrid polymer. As a result, an output voltage, the output current and the output power of the piezoelectric/conductive hybrid polymer are increased.
