METHOD FOR MANUFACTURING A PIEZOELECTRIC FILM CAPABLE OF CONTROLLING THE THICKNESS OF A PIEZOELECTRIC FILM TO BE CORRESPONDED TO A PIEZOELECTRIC CHARACTERISTIC ACCORDING TO THE VARIATION OF A THICKNESS

摘要

PURPOSE: A method for manufacturing a piezoelectric film is provided to determine the thickness of a piezoelectric film without a separate condition by including a stopper with a constant height on a heating-press.;CONSTITUTION: The piezoelectric material of a pellet shape is fused on the heat plate of the heating press which is heated by processing temperature(S1). The piezoelectric material is pressurized with processing pressure through the compression plate of the heating press(S3). The piezoelectric material heated and pressured is naturally frozen through the heating press(S5). An electrode is coated in the top and the lower part of the polymer film manufactured(S7). A certain voltage is applied to the polymer film in which the electrode is coated in the top and lower part(S9).;COPYRIGHT KIPO 2012
