For purposes of explanation, various descriptions are set forth herein to provide an understanding of the present invention. It is evident, however, that such embodiments may be practiced without these specific details. In other instances, well-known structures and devices are shown in block diagram form in order to facilitate describing the embodiments.

The following description provides a simplified description of one or more embodiments in order to provide a basic understanding of embodiments of the invention. This section is not a comprehensive overview of all possible embodiments and is not intended to identify key elements or to cover the scope of all embodiments of all elements. Its sole purpose is to present the concept of one or more embodiments in a simplified form as a prelude to the more detailed description that is presented later.

FIG. 1 is a diagram of a hybrid power generation apparatus capable of generating triboelectric energy and electromagnetic energy according to an embodiment of the present invention. Referring to FIG.

1, a hybrid electric power generating apparatus capable of generating triboelectric energy and electromagnetic energy according to an embodiment of the present invention includes a first electrode 12; A first triboelectrifying layer (10) disposed on the first electrode; A second frictional electrifiable body layer disposed opposite to the first frictional electrifiable body layer and capable of repeating contact and noncontact states with the first frictional electrifiable body layer and having a charging property opposite to that of the first frictional electrifiable body layer A charging layer (20); A second electrode (22) disposed on the second tribo charging body layer; A high permeability material layer (30) disposed on the second electrode; A coil 40; And a magnet (50) disposed away from the coil.

The first electrode 12 and the second electrode 22 may be any of those available as electrodes, and there is no particular limitation to such electrodes.

The first tribo charging body layer 10 and the second tribo charging body layer 20 are disposed so as to be opposed to each other and arranged so as to be able to repeat contact and noncontact states with each other. 1, the portion including the second triboelectrifier layer 20 is shown as being in the A position, but it is moved to the B position (indicated by the dotted line) so that the first triboelectrifier layer 10 and the second triboelectrifier layer (20) can contact each other. In FIG. 1, the portion including the second triboelectrifier layer 20 is shown as movable to a position between A-B-C, and this movement can generate electromagnetic energy as described below.

1, a portion including the second triboelectrifier layer 20 is moved and a portion including the first triboelectrifier layer 10 is shown as being fixed, but the present invention is not limited thereto. However, in order to generate electromagnetic energy, it is preferable that a portion including the high permeability material layer 30 moves.

On the other hand, the first and second tribo charging body layers 10 and 20 should be made of different materials. In this case, preferably, the two charging layers are made of materials having different charging characteristics. The fact that the charging characteristics are different from each other means that the charging characteristics are arranged at different positions on the triboelectric series, and the larger the difference in the charging characteristics, the larger the triboelectricity can be generated.

A layer of high permeability material 30 is disposed on the second electrode 22. The high permeability material layer may be a material having high permeability, and generally means a ferromagnetic material having a high permeability. As such a high permeability material, Si-Fe, Co-Fe, Ni-Fe, ferrite and the like can be used.

In the present invention, as the second friction layer 20, to which the high permeability material layer 30 is attached, moves to the same position as the ABC, a change in the magnetic field distribution occurs due to the movement of the high permeability material, The magnetic field is changed, that is, the magnetic flux is changed to generate electromagnetic energy.

The coil 40 is not limited to a specific material, and it is common to use a material having high conductivity such as Cu. The coil is the first electrode in the hybrid device of the present invention; The first triboelectrify body layer; The second triboelectrifier layer; The second electrode; And are arranged side by side along the high permeability material layer. That is, as shown in FIG. 1, the coil 40 is connected to the first electrode; The first triboelectrify body layer; The second triboelectrifier layer; The second electrode; And the magnetic permeability due to the movement of the high permeability material layer 30 can be changed by being arranged along the high permeability material layer.

In order to increase the change of magnetic flux, the first electrode; The first triboelectrify body layer; The second triboelectrifier layer; The second electrode; And the high permeability material layer is disposed so as to pass through the coil. That is, as the high permeability material layer moves while passing through the coil along the longitudinal direction of the coil, the change of the magnetic flux is greatest, and high electromagnetic energy can be obtained.

The magnet 50 is disposed apart from the coil 40, and there is no particular limitation on the magnet 50.

Hereinafter, the principles of the triboelectric energy generation and the principle of electromagnetic energy generation of the hybrid power generation apparatus according to one embodiment of the present invention will be described.

FIG. 3 is a view for explaining the principle of generation of triboelectric energy in a hybrid power generation apparatus capable of generating triboelectric energy and electromagnetic energy according to an embodiment of the present invention.

As shown in FIG. 3, the upper plate and the lower plate come into contact with each other due to external application of force or the like, and are opposite to each other due to the relative permittivity difference. For convenience, the top plate is labeled as (+) and the bottom plate as (-).

Then, when the plate and the lower plate are in non-contact with each other, a charge is moved to maintain the balance due to the potential difference between the two plates, thereby causing current to flow. As the charge moves and becomes electrically balanced, the flow of charge no longer occurs.

If a force is externally applied in this state, the current flows again in the same manner as described above.

4 is a view for explaining the principle of generating electromagnetic energy in a hybrid power generation apparatus capable of generating triboelectric power and electromagnetic energy according to an embodiment of the present invention.

Assuming that the initial state is the same as the leftmost part of FIG. 4, the description will start. When external force is applied, the gap between the upper plate and the lower plate becomes narrower, and when the external force is applied in the opposite direction, the gap between the upper plate and the lower plate becomes wider. The direction of the force can be varied and this description is exemplary. As the upper plate in which the high permeability material is located moves by the external force, the magnetic field formed from the magnet is changed by the high permeability material, and the magnetic flux density passing through the coil is changed by the deformation of the magnetic field distribution.

The electromagnetic energy flows in accordance with the change in the amount of the magnetic field (magnetic flux) passing through the coil, thereby obtaining the electromagnetic energy. That is, electromagnetic energy is harvested using the change in magnetic flux caused by a material having a high magnetic permeability.

In summary, triboelectricity is generated as the first triboelectrify layer shifts from the contact state to the non-contact state, and a change in magnetic flux is generated as the high permeability material layer is connected to the first triboelectric layer, Energy is generated.

The energy storage unit 63 may further include a lead portion 61 connected to the first electrode and the second electrode to collect the triboelectric energy generated by the friction, . A rectifier diode 62 may be connected between the lead portion 61 and the energy storing portion 63.

The energy storage unit 73 may further include a lead portion 71 connected to both ends of the coil 40 to collect the electromagnetic energy generated by the change of the magnetic flux and the lead portion 71 may be connected to the energy storage portion 73 A rectifying diode 72 may be connected between the lead portion 71 and the energy storing portion 73. [

The lead-out portion includes an electrode, and an energy storage portion such as a battery is electrically connected to the lead-out portion. A rectifier diode (not shown) may be connected between the lead portion and the energy storage portion. A load may be connected to the drawer, thereby directly lighting the bulb. The diode serves as a rectifying diode to allow a current to flow only in one direction, thereby preventing current from flowing in reverse and discharging the capacitor or the like.

Figure 2 is a diagram of a hybrid power generation system capable of triboelectric and electromagnetic energy generation in accordance with a further embodiment of the present invention. The difference between the embodiment of FIG. 2 and the embodiment of FIG. 1 is that in the case of FIG. 2, there is no separate electrode in the second triboelectrifier layer and the second triboelectrifier layer is made of a material having a conductive material, And serves as a two-electrode. 1 except that the second triboelectrifiable body layer serves as the second electrode. Therefore, only the difference from the embodiment of FIG. 1 will be described by omitting the duplicate description.

In the embodiment of FIG. 2, the second triboelectrifying body layer is made of a material having electrical conductivity and being different in charging property from the first triboelectrifying body layer, and performs the role of the second electrode itself at the same time. Therefore, in the embodiment of FIG. 2, the lead-out portion is connected to the first electrode and the second friction layer entire layer.

As shown in FIG. 5, it was confirmed that the triboelectric energy was outputted according to the change of the contact state between the entire first friction pad and the entire second friction pad.

As shown in FIG. 6, it was confirmed that the change of the magnetic field occurred due to the movement of the high permeability material. From this, it was confirmed that the electromagnetic energy was generated by the change of the magnetic flux.
