Device and method for driving magnetic suspension graphene ship to move for long range by using laser

Abstract

The invention discloses a device and a method for driving a magnetic suspension graphene ship to move for a long range by utilizing laser, and belongs to the technical field of light-operated solid motion, and the method comprises the steps of designing a graphene ship, constructing a specific graphene ship motion track by utilizing neodymium iron boron magnets, and utilizing light radiation force to drive the magnetic suspension graphene ship to move for a long range. Due to the momentum difference of gas molecules on the two sides of the sail, the graphene ship obtains pushing force, and therefore the graphene ship is controlled to achieve long-range movement on a specific magnetic track. The device has the advantages of being simple in structure, easy and accurate to control, free of contact, controllable in rotation direction and speed, controllable in long-range movement distance and speed, controllable in movement track and the like, and the graphene ship can be pushed to move in a long range only under the conditions that a light source is provided by laser, a specific track is formed by the neodymium iron boron magnet and certain vacuum degree is needed; the material can be widely applied to the fields of rapid transportation and light energy conversion.

Description

technical field [0001] The invention belongs to the technical field of light-controlled solid motion, and discloses a device and a method for using a laser to drive a long-range motion of a maglev graphene boat. Background technique [0002] Currently, using light to manipulate objects has many advantages, such as being untouchable, remote and pollution-free. Most methods are performed in a liquid environment. The most common way is to rely on the radiation pressure and potential energy of the light itself, such as optical tweezers. However, the forces created by radiation pressure and potential energy are too weak to manipulate objects on the nanometer scale. In order to expand the scale of manipulating objects, another approach that has emerged in recent years is to use the energy generated by the interaction of light with the object to affect the properties of the medium and in turn push the object, such as the photothermophoresis effect, in which the temperature gradie...

Problems solved by technology

[0004] (1) Existing methods for light manipulation of objects often occur in a liquid environment, and the operating environment is single. In addition, these methods can only manipulate micron-scale objects and the manipulation speed is very low

[0005] (2) The existing method of using light to manipulate objects in a gas environment, the drive of light to objects is limited to micron-scale objects and ultra-short-distance manipulation, and it is impossible to achieve long-distance manipulation of centimeter-level objects

[0006] The difficulty in solving the above problems and defects is as follows: 1. Conventional methods for light manipulation of objects often have a single effect on the environment, can only manipulate micron-sized objects, and the manipulation speed is very low

[0007] 2. The existing method of using light to manipulate objects in a gas environment, the drive of light to objects is limited to micron-scale objects and ultra-short-distance manipulation
