Abstract
A suspension comprises a load beam having a leading portion and a trailing portion, a gimbal sheet mounted to the leading portion and forming a first pad, a second pad, and a displacement lever assembly including at least a first lever arm having a first end adjacent and connected to the first pad and a second end opposite the first end and connected to the second pad. The displacement lever assembly is configured to translate a linear displacement of the first pad to a differing displacement of the second pad. The suspension comprises a piezoelectric element attached to the first pad and extending across the second pad.
