FLEXIBLE PIEZOELECTRIC ELEMENT AND ITS MANUFACTURING METHOD |
摘要 |
<p>PROBLEM TO BE SOLVED: To solve the problem where this type of conventional piezoelectric elements requires a complex manufacturing process and the piezoelectric element with a large area can not be manufactured easily. SOLUTION: Since the flexible piezoelectric element has a compound piezoelectric sheet 4 where a plurality of flat-plate-shaped piezoelectric ceramics 1 are arranged in macromolecular base materials 2a and 2b, and electrodes 3a and 3b that are arranged on both the surfaces of the compound piezoelectric sheet 4 while the macromolecular base materials are arranged between the flat-plate- shaped piezoelectric ceramics 1 and one of the electrodes, the piezoelectric element can be manufactured by such a simple manufacturing method as the press method. Also, the area of the element can be increased easily.</p> |
