Abstract
A light beam scanner may include a polymeric material and a soft magnetic material.
Claims11
A method for actuating a mechanical device comprising:
- applying a magnetic field in a first direction;
- inducing a magnetization constrained by shape anisotropy in a second direction along an axis of a soft magnetic material responsive to the magnetic field in the first direction;
- inducing a first mechanical motion as a result of an interaction between the magnetic field applied in the first direction and the induced magnetization of the soft magnetic material in the second direction;
- applying a magnetic field in a third direction opposite the first direction;
- inducing a magnetization constrained by shape anisotropy in a fourth direction opposite the second direction along an axis of a soft magnetic material responsive to the magnetic field in the third direction;
- and
- inducing a second mechanical motion opposite the direction of the first mechanical motion as a result of an interaction between the magnetic field applied in the third direction and the induced magnetization of the soft magnetic material in the fourth direction.

A light beam scanner comprising:
- a mounting structure;
- an epoxy-fiberglass substrate coupled to the mounting structure and configured to periodically oscillate in a bending motion around at least one axis of rotation;
- a first magnetic actuator portion coupled to the mounting structure;
- and
- a second magnetic actuator portion coupled to the epoxy-fiberglass substrate wherein the first and second magnetic actuator portions are operable to cooperate to actuate periodic oscillation of the epoxy-fiberglass substrate.
