example 1

[0263] In this example, using an anode and a cathode, oil used as an insulating fluid, and water droplets used as a dielectric body, it was demonstrated whether rotational motion occurs. The materials and methods are as follows:

[0264] (Materials and Methods)

[0265] (about figure 2 )

[0266] Anode: made of tungsten (manufactured by NPS co., LTD.)

[0267] Cathode: made of tungsten (manufactured by NPS co., LTD.)

[0268] Oil: Mineral oil (produced by Nacalai Tesque)

[0269] Water droplet: prepared from phospholipid DOPC (manufactured by Wako Pure Chemical Industries, Ltd.)

[0270] Electrode Arrangement: The anode and cathode were arranged 50 microns apart from each other in the direction parallel to the central axis and in the direction perpendicular to the central axis.

[0271] The way of applying voltage: 100V constant voltage

[0310] (Example 2: Material of Dielectric Body)

[0311] In this example, it was shown that various conditions were tested and the results revealed the following features. Basic experimental techniques were performed according to Example 1.

[0312] (material of dielectric body)

[0313] In this example, it was confirmed that the dielectric body may be of any material, and it was confirmed that, in addition to minute water droplets, movable polyethylene beads, glass beads, etc. also perform similar motions.

[0314] (Example 3: Electrode material)

[0315] In this example, it was shown that various conditions were tested and the results revealed the following characteristics. Basic experimental techniques were performed according to Example 1.

[0316] In this example, confirm that the material of the electrodes is not relevant (only conductivity is required). That is, confirmed by tungsten, tungsten carbide and gold. image 3 is an instance of tungsten, Figure 4 is an example of tungsten carbide, gold has also been confirmed to have a similar effect.

Abstract

Provided is a technique, wherein, in a micro-size, an object can be moved at will without generating a current and transported to retrieve the mechanical work. As a result of earnest consideration, the inventors have found out that a dielectric body can be three-dimensionally transported at will simply by arranging two electrodes for generating an electric field in, for example, a dielectric body of a micro-size or the like in an insulation fluid such as oil, in such a manner that the central axes of the two electrodes are not on the same line, and applying an electric field (for example, constant electric field) thereto, thereby making it possible to retrieve the mechanical work, and have solved the problem.

Description

technical field [0001] The present invention relates to the transport of micron-sized objects and the harvesting of mechanical work through a constant electric field. Background technique [0002] Typically, alternating electric fields are used for oscillatory and periodic motion. In this case, motion is caused by the generation of electric current. [0003] In the micron scale, it is considered difficult to extract work from mechanical motion due to the low Reynolds number representing the magnitude ratio between the inertial and viscous forces of the flow. [0004] Non-Patent Document 1 describes the effect of a constant electric field on water droplets having a diameter of several tens of micrometers in oil. [0005] The micron-scale range, which is the subject of the present invention, is generally also considered to be the low Reynolds number range. In the category of this scale, it is well known that only doing periodic motion on a straight line without direction ca...
