Abstract

PURPOSE:To maintain high piezo-electric characteristics without no influence to the essential qualities of thermoplastic resion and to utilize macromolecular piezoelectric material at its maximum by forming an Al evaporation pole in its thickness 0.05 to 1.0mu on the both side of a flexible film type macromolecular piezoelectric material.
