Abstract: | A new method of fabricating PZT/potymer composites with 2-2 connectivity is described. This fabrication technique offers significant advantages over conventional dice-and-fill fabrication methods, and the composites exhibit the high electromechanical coupling expected from conventional PZT/polymer composites. In this method, thin (≤20μm) sintered PZT plates and sheets of a thermoplastic polymer film (≤6 μm) are bonded together via thermal processing. A technique for sintering thin, flat PZT plates from tape cast materials was developed to provide the necessary PZT plates. The resulting composite blocks were cut to required dimensions, electroded, and poled. Electromechanical properties were measured to evaluate the composites. |
