Provided is a novel actuator that can easily achieve movement with multiple degrees of freedom. An actuator includes a flexible electrode, a first base electrode disposed to face the flexible electrode on the Y-axis and provided with a first insulating layer on an opposite face, a second base electrode disposed to face the flexible electrode on the X-axis and provided with a second insulating layer on an opposite face, and a first output member and a second output member adapted to be displaced according to deformation of the flexible electrode. A first space is formed between the first insulating layer and the flexible electrode, in which the flexible electrode deforms toward the first insulating layer by an applied voltage. A second space is formed between the second insulating layer and the flexible electrode, in which the flexible electrode deforms toward the second insulating layer by an applied voltage.

The disclosure relates to a drive means for non-resonant linear and/or rotary positioning of an object, comprising at least two piezoelectric or electrostrictive actuator groups, where-in a first actuator group moves a first runner portion relative to a stationary base of the drive means according to the principle of an inertia drive, and by means of the second actuator group a second runner portion is moved relative to the first runner portion with a limited range of movement in the high-resolution scan mode, wherein a common electrical control signal is applied to the first and second actuator groups.

Exemplary practice of the present invention provides a magnetostrictive actuator characterized by linear force output and uniform magnetic biasing. A center bias magnet combined with a flux transfer tube produces a uniform magnetic bias down the length of a magnetostrictive component. Depending on the inventive embodiment, the magnetostrictive component may include one magnetostrictive element or a pair of collinear magnetostrictive elements. A center bias magnet, in combination with a flux transfer tube, drives magnetic flux through the magnetostrictive component (e.g., a series of magnetostrictive rods) in opposite directions, while surrounding drive coils apply flux in the same direction through the magnetostrictive component. The net response is substantially linear with respect to the drive coil current. The flux transfer tube applies distributed magnetic flux to the magnetostrictive component at a rate that ensures uniform magnetic flux density down the length of the magnetostrictive component.
