Abstract
A method for making a piezoelectric actuator comprises coating at least one of a first surface and a second surface of a piezoelectric element with a polyimide adhesive. The piezoelectric element is then heated to dry the adhesive. Afterwards, the piezoelectric element is inserted between a first metallic layer and a second metallic layer to form an assembly. The assembly is placed in a press. While the assembly is in the press, the polyimide adhesive is cured at a curing temperature which does not depole the piezoelectric element, thereby bonding the piezoelectric element between the first metallic layer and the second metallic layer.
