摘要：
A suspension assembly includes a load beam, a mount plate, first and second piezoelectric microactuators, and a flex circuit segment. The first piezoelectric microactuator is electrically non-conductively attached to the load beam and the mount plate. The first piezoelectric microactuator includes a first piezoelectric element, a first top electrode, and a first bottom electrode. The second piezoelectric microactuator is electrically non-conductively attached to the load beam and the mount plate. The second piezoelectric microactuator includes a second piezoelectric element, a second top electrode, and a second bottom electrode. The flex circuit segment is disposed folded about the first and second piezoelectric microactuators. The flex circuit segment is in electrical communication with the first top electrode, the first bottom electrode, the second top electrode, and the second bottom electrode.
