Abstract
A device (100) for the excitation of a fiber (150) comprises a first piezo bender actuator (110) and a second piezo bender actuator (120). The device (100) also comprises a connection part (130) which is arranged between the first piezo bender actuator (110) and the second piezo bender actuator (120). The device (100) also comprises a movable fiber (150) which is mounted to the connection part (130).
Claims24
A device for the excitation of a fiber-shaped element, which comprises:
- a first piezo bender actuator,
- a second piezo bender actuator,
- a connection part, which is arranged between the first piezo bender actuator and the second piezo bender actuator, and
- a movable fiber-shaped element, which is mounted to the connection part;
- wherein the first and second piezo bender actuators each are planar, in a resting position, and wherein the first and second piezo bender actuators are co-planar in a direction that is perpendicular to a direction of a bending of the first and second piezo bender actuators.
A method for exciting a fiber-shaped element which extends away from a connection part which is arranged between a first piezo bender actuator and a second piezo bender actuator, wherein the first and second piezo bender actuators each planar, in a resting position, and wherein the first and second piezo bender actuators are co-planar in a direction that is perpendicular to a direction of a bending of the first and second piezo bender actuators, the method comprising:
- controlling the first piezo bender actuator with a first signal form, and
- controlling the second piezo bender actuator with a second signal form.
A system which comprises:
- an elongate first housing,
- an elongate second housing which extends at least in a section along the first housing,
- a high-frequency antenna which is arranged in the first housing, and
- a device arranged in the second housing, the device comprising:
- a first piezo bender actuator,
- a second piezo bender actuator,
- a connection part, which is arranged between the first piezo bender actuator and the second piezo bender actuator, and
- a movable fiber-shaped element, which is mounted to the connection part.
