Patent ID: 8520327

Claim:
A piezoelectric inertia driver for optical adjustment, comprising: a rigid body portion having a first piezoelectric member mount surface and a bottom surface; a continuous and flexible resilient member having a first end which includes a second piezoelectric member mount surface, a drive surface portion having a drive surface, the drive surface extending furthest from the bottom surface allowing the drive surface to engage a surface of a body to be driven, an axially rigid portion disposed between and secured to the drive surface portion and the first end, an S-shaped resilient portion extending from the from the drive surface portion, the S-shaped portion having a first bend under the drive surface portion towards the first end portion and a second bend redirecting the S-shaped portion towards a second end portion, and the second end portion being disposed between and secured to the S-shaped resilient portion and the rigid body portion; and a piezoelectric member disposed between and secured to the first and second mount surfaces.
