METHOD OF MANUFACTURING A MULTI-LAYERED PIEZOELECTRIC ACTUATOR

摘要

Method of manufacturing a piezoelectric actuator. The method includes a pre-cure step in which the adhesive is heated to a temperature below the melting point of the adhesive. A stack is formed having a piezoelectric layer (212) and at least one supporting layer (216, 218) with the pre-cured adhesive (220, 222) therebetween. The stack (300) is then cured to form a bonded laminate. The temperature at which the pre-cure occurs allows for the pre-stress in the piezoelectric layer (212) to be modified without changing the material of the supporting layer (216, 218).
