The upper voltage distribution module (a-100) is provided with a first upper insulating layer (a-111) stacked on the upper basic electrode (a-10) and a first upper side stacked on the first upper insulating layer (a-111). The second upper side insulating layer a-112 stacked on the electrodes a-121, the first upper side additional electrode a-121, and the second upper side stacked on the second upper insulating layer a-112. It may include the electrodes (a-122). The lower voltage distribution module (b-200) is provided with a first lower insulating layer (b-211) stacked on the lower basic electrode (b-20) and a first lower side stacked on the first lower insulating layer (b-211). The second lower side addition layer stacked on the electrode (b-221), the second lower side insulating layer (b-212) stacked on the first lower side additional electrode (b-221) It may include an electrode (b-222).

When the pressure P is applied to the energy harvesting element 1 in a specific direction, the dielectric material inside the piezoelectric body c-31 is polarized in a specific direction so that the upper side (a, the upper base electrode a-10 and the upper side) are polarized. The potential is induced to the electrodes of the voltage distribution module (a-100) and the lower side (b, the lower basic electrode (b-20) and the lower voltage distribution module (b-200)). Specifically, when a piezoelectric phenomenon occurs, + potential is induced to the upper base electrode a-10, and-potential is induced to the lower base electrode b-20, the potential induced to the upper base electrode a-10 is induced. According to the polarity (+), the first insulating layer (a-111) causes polarization, and the potential (+) and the opposite potential (-) of the upper base electrode (a-10) are the first upper additional electrode (a). -121). Similarly, due to polarization of the second upper insulating layer (a-112), the potential (-) and the opposite potential (+) of the first upper additional electrode (a-121) are opposite to the second upper additional electrode (a-122).

Similarly, according to the polarity of the potential induced in the lower base electrode b-20, the first insulating layer b-211 causes polarization, and is opposite to the potential (-) of the lower base electrode b-20. The potential (+) is induced to the first lower additional electrode b-221. Similarly, due to polarization of the second lower insulating layer b-212, the potential (+) and the opposite potential (−) of the first lower additional electrode b-221 are opposite to the second lower additional electrode b-222.

Accordingly, the first current Ia1 is oriented in one direction along the pair of first upper and lower lead lines a-310 and b-310 connected to the upper basic electrode a-10 and the lower basic electrode b-20. Flows in the opposite direction along a pair of second upper and lower lead lines a-320 and b-320 connected to the first upper additional electrode a-121 and the first lower additional electrode b-221.

The third current Ia3 flows in one direction along (). When the pressure P applied to the piezoelectric power generator 1 disappears, the first current Ia1, the second current Ia2, and the third current Ia3 flow in the direction when the pressure P is present.

The first current Ia1 flowing along the first upper lead line a-310 and the first lower lead line b-310 is a conventional energy harvesting without the voltage distribution modules a-100 and b-200. It outputs a voltage slightly lower than the current Io generated in the element 2. The second current Ia2 flowing along the second upper lead line a-320 and the second lower lead line b-320 outputs a voltage whose voltage is slightly lower than the first current I a1. The third current Ia3 flowing along the third upper lead line a-330 and the third lower lead line b-330 outputs a voltage whose voltage is slightly lower than the second current Ia2. When a piezoelectric phenomenon generating the same energy occurs, it induces a potential difference to the base electrodes a-10 and b-20 and the first additional electrodes a-121 of the voltage distribution modules a-100 and b-200. This is because energy is distributed to induce a potential difference between the b-221 and the second additional electrodes a-122 and b-222.

At this time, when passing through the rectifier 410 having the same reference voltage, the amount of electrical energy passing through the rectifier 411 connected to the first upper lead line (a-310) and the first lower lead line (b-310). (Ep1), the amount of electrical energy Ep2 and the third upper lead line (a-) passing through the rectifier 412 connected to the second upper lead line (a-320) and the second lower lead line (b-320). 330 and the amount Ep3 of the electric energy passing through the rectifier 413 connected to the third lower leader line b-330, the electric energy passing through the rectifier in the piezoelectric power generator 2 without the voltage distribution structure. Is greater than the amount Ep (Ep1 + Ep2 + Ep3> Ep). Since the electrical energy output at a voltage higher than the reference voltage of the rectifier 410 is distributed and output to the electrodes of the voltage distribution modules a-100 and b-200, the amount of electrical energy output at a voltage lower than the reference voltage increases. Finally, the amount of electrical energy passing through the rectifier 410 increases.

Therefore, when the same external pressure (P) is injected into the piezoelectric power generator to generate a piezoelectric phenomenon, the amount of electrical energy that can be obtained in the energy harvesting device (1) having a voltage distribution structure according to an embodiment of the present invention (Ep1 + Ep2 + Ep3) is more than the amount of electrical energy (Ep) that can be obtained in a piezoelectric generator (2) without a voltage distribution structure.

When the frictional charge occurs, the upper base electrode (a-10) is charged with +, and when the-potential is induced to the lower base electrode (b-20), the polarity of the potential charged with the upper base electrode (a-10) According to (+), the first insulating layer (a-111) causes polarization, and the potential (+) of the upper base electrode (a-10) and the opposite potential (-) are the first upper additional electrodes (a-121). Is induced. Similarly, due to polarization of the second upper insulating layer (a-112), the potential (-) and the opposite potential (+) of the first upper additional electrode (a-121) are opposite to the second upper additional electrode (a-122). Induced to. Similarly, according to the polarity of the potential induced in the lower base electrode b-20, the first insulating layer b-211 causes polarization, and is opposite to the potential (-) of the lower base electrode b-20. The potential (+) is induced to the first lower additional electrode b-221. Similarly, due to polarization of the second lower insulating layer b-212, the potential (+) and the opposite potential (−) of the first lower additional electrode b-221 are opposite to the second lower additional electrode b-222. Induced to.

The lower base electrode from the upper base electrode a-10 through a pair of first leader lines a-310 and b-310 connected to the upper base electrode a-10 and the lower base electrode b-20, respectively. Current Ib1 (friction electricity) flows in the direction of (b-20). At the same time, the first upper additional electrodes (a-320 and b-320) are connected to the first upper additional electrodes (a-121) and the first lower additional electrodes (b-221), respectively. The current Ib2 flows from the b-221 to the first upper additional electrode a-121. In the same manner, the second upper additional electrode is connected to the second upper additional electrode a-122 and the second lower additional electrode b-222 through a pair of third lead lines a-330 and b-330, respectively. The current Ib3 flows from (a-122) to the second lower additional electrode b-222. On the contrary, the upper side (a, upper base electrode (a-10) and the upper voltage distribution module (a-100) move so that one surface of the upper base electrode (a-10) and the contact (c-32) are released from contact. In this case, the currents Ib1, Ib2, and Ib3 flow in opposite directions when the triboelectric charge is generated.

The voltage magnitude of the current Ib1 flowing along the first leader lines a-310 and b-310 is smaller than the voltage of the current when there is no voltage distribution structure, and the second leader lines a-320 and b-320 The voltage magnitude of the current Ib2 flowing through is smaller than the voltage magnitude of the current Ib1 flowing along the first leader lines a-310 and b-310, and the third leader lines a-330 and b-330. The voltage magnitude of the current Ib3 flowing through) is smaller than the voltage magnitude of the current Ib2 flowing along the second leader lines a-320 and b-320. When the frictional charging with the same energy occurs, the potential difference is formed between the base electrodes a-10 and b-20 and the first additional electrodes a-121, the voltage distribution modules a-100, b-200. This is because energy is distributed to the potential difference between the b-221 and the second additional electrodes a-122 and b-222.

Therefore, as described in the operation of the piezoelectric power generator Gd1 of FIG. 2B, since the power output at a voltage lower than the reference voltage of the rectifying unit 410 increases, frictional charging in the triboelectric power generator is performed by the same contact or friction. When generated, the amount of electrical energy (Ep1 + Ep2 + Ep3) that can be obtained in the energy harvesting device 1 having the voltage distribution structure according to the embodiment of the present invention is a triboelectric power generator having no voltage distribution structure ( It is more than the amount of electrical energy (Ep) that can be obtained in 2).

2d is a view showing the operation of the energy harvesting device 1 having a voltage distribution structure of the liquid friction power generation method according to an embodiment of the present invention.

In the energy harvesting device 1 having the voltage distribution structure according to the embodiment of the present invention shown in FIG. 2D, the power generator is coplanar with the upper base electrode a-10 and the upper base electrode a-10. It includes a lower base electrode (b-20), an upper base electrode (a-10) and a charge electrode (c-33) covering the lower base electrode (b-20) to be spaced apart on the hydrophobic film (d-40) The droplet 60 flows from the upper base electrode (a-10) to the lower base electrode (b-20) or in the opposite direction to the upper base electrode (a-10) and the lower base electrode (b-20). Liquid friction generator (Gd3) for generating electrical energy, the upper voltage distribution module (a-100) is formed on the upper basic electrode (a-10), the lower voltage distribution module (b-20) on the lower basic electrode (b-20) b-200 is formed, the electrical energy generated by the interaction with the charge (c-33) by the movement of the liquid droplet 60 is the upper base electrode (a-10) and the lower base electrode (b-20) And upper part It is distributed to the electrode (a-121, a-122) and the lower electrode portion (b-221, b-222) is output. An insulating material 50 for insulation may be formed between the upper side (a) and the lower side (b). When the liquid droplet 60 is water, in order to facilitate the movement of the droplet, a hydrophobic film d-40 may be further formed on the charger c-33.

In the liquid friction power generator Gd3, when the liquid droplet 60 is located on the upper side a on the charged member c-33, the charging sequence difference between the charged member c-33 and the liquid droplet 60 is different. The liquid droplet 60 is charged by + and one surface of the charged material c-33 is charged by-, and the other surface of the charged material c-33 is charged by + and the charged material c-33 is The upper basic electrode (a-10) in contact with the other surface of is charged with-. In other words, when an electric dipole is expressed as an electric charge distributed in the interior of the electrification c-33, in a disordered state of the electric dipole, between the liquid drop 60 and the electrification c-33 Due to the difference in charging sequence, the -pole of the electric dipole in the electrified body c-30 faces the liquid droplet 60 and the + pole faces the upper base electrode a-10, so that the upper base electrode b- 20) is charged to-.

When liquid friction occurs, when the upper base electrode (a-10) is charged to-, the lower base electrode (b-20) has a relatively + potential, and the lower base electrode (a-10) has a potential of being charged to the upper base electrode (a-10). According to the polarity (−), the first insulating layer (a-111) causes polarization, and the potential (−) of the upper base electrode (a-10) and the opposite potential (+) are the first upper additional electrodes (a-). 121). Similarly, due to polarization of the second upper insulating layer (a-112), the potential (+) and the opposite potential (-) of the first upper additional electrode (a-121) are opposite to the second upper additional electrode (a-122). Induced to. Similarly, depending on the polarity of the potential induced in the lower base electrode b-20, the first insulating layer b-211 causes polarization and is opposite to the potential (+) of the lower base electrode b-20. The potential (−) is induced to the first lower additional electrode b-221. Similarly, due to the polarization of the second lower insulating layer b-212, the potential (−) and the opposite potential (+) of the first lower additional electrode b-221 are opposite to the second lower additional electrode b-222. Induced to.

The upper base electrode from the lower base electrode b-20 through a pair of first leader lines a-310 and b-310 connected to the upper base electrode a-10 and the lower base electrode b-20, respectively. The current Ic1 flows in (a-10). At the same time, the first upper additional electrodes (a-320 and b-320) are connected to the first upper additional electrodes (a-121) and the first lower additional electrodes (b-221), respectively. The current Ic2 flows from the a-121 to the first lower additional electrode b-221. The second lower additional electrodes b-through the pair of third leader lines a-330 and b-330 respectively connected to the second upper additional electrodes a-122 and the second lower additional electrodes b-222. The current Ic3 flows to the second upper additional electrodes a-122 from 222. When the liquid droplet 60 moves to the lower side b, currents Ic1, Ic2, and Ic3 flow in the opposite directions when the liquid droplet 60 is on the upper side a.

The voltage magnitude of the current Ic1 flowing along the first leader lines a-310 and b-310 is smaller than the voltage of the current when there is no voltage distribution structure, and the second leader lines a-320 and b-320. The voltage magnitude of the current Ic2 flowing through is smaller than the voltage magnitude of the current Ic1 flowing along the first leader lines a-310 and b-310, and the third leader lines a-330 and b-330. The voltage magnitude of the current Ic3 flowing through) is smaller than the voltage magnitude of the current Ic2 flowing along the second leader lines a-320 and b-320. This is because when the same liquid droplet 60 comes into contact with the charging material c-33 to generate electric energy, it induces a potential difference to the base electrodes a-10 and b-20, and the voltage distribution module a-100, This is because energy is distributed to induce a potential difference between the first additional electrodes a-121 and b-221 and the second additional electrodes a-122 and b-222 of the b-200.

Therefore, as described in the operation of the piezoelectric power generator Gd1 of FIG. 2B, since the power output at a voltage lower than the reference voltage of the rectifying unit 410 increases, frictional charging in the triboelectric power generator is performed by the same contact or friction. When generated, the amount of electrical energy (Ep1 + Ep2 + Ep3) that can be obtained from the energy harvesting device 1 having the voltage distribution structure according to the embodiment of the present invention is in a liquid friction power generator without a voltage distribution structure. More than the amount of electrical energy (Ep) that can be obtained.

3 is a diagram illustrating an energy harvesting device 1 having a voltage distribution structure having different areas of electrodes according to an embodiment of the present invention.

As shown in FIG. 3, the energy harvesting device 1 having the voltage distribution structure according to the embodiment of the present invention has an area of an electrode located farther than an area of an electrode located closer to the generator Gd. It can be formed large.

The upper base electrode (a-10) and the lower base electrode (b-20) closest to the generator Gd where electric energy is generated by pressure application, contact friction, or liquid friction are formed with the smallest area, and Next, the first upper additional electrodes (a-121) and the first lower additional electrodes (b-221) to be stacked are formed larger than the areas of the base electrodes (a-10 and b-20), and the next stacked additional electrodes The second upper additional electrodes a-122 and the second lower additional electrodes b-222 may be larger than the areas of the first additional electrodes a-121 and b-121. That is, the area of the electrode closest to the generator Gd may be the smallest, and the area of the electrode farthest from the generator Gd may be the largest. In addition, the areas of the pair of electrodes in the corresponding order may be formed identically. For example, the areas of the upper base electrode a-10 and the lower base electrode b-20 are the same, and the areas of the first upper additional electrode a-121 and the first lower additional electrode b-221 are the same. This can be formed identically.

In the electrode close to the generator Gd, a potential difference generated by piezoelectric phenomenon, triboelectric charging or liquid friction is strongly formed, and as the distance from the generator Gd increases, the influence of the electric field or polarization decreases. Therefore, the electrode area close to the generator Gd is made small, and the electrode areas are sequentially enlarged in the direction away from the generator Gd, so that the potential difference induced by the pair of electrodes positioned near the generator Gd and The potential difference induced in the pair of electrodes far from the generator Gd can be formed uniformly, and the voltages of the currents Id1, Id2, and Id3 outputted by the plurality of lead lines can be made uniform.

As shown in FIG. 2A, when the area of the electrode is the same, the voltage of the current Ia1 outputted to the first upper lead line a-310 and the first lower lead line b-310 is the highest and is the third. Since the voltage of the current Ia3 outputted to the upper leader line a-330 and the third lower leader line b-330 is the lowest, the amount of electric energy passing through the rectifying unit 410 (Ep1> Ep3) is unbalanced. .

However, as shown in FIG. 3, when the electrode areas are sequentially enlarged in the direction away from the power generator Gd, the first upper leader line a-310 and the first lower leader line b-310 are formed. Currents Id1 and Id2 output to the second upper leader line a-320 and the second lower leader line b-320, the third upper leader line a-330, and the third lower leader line b-330. The voltage of Id3 may be equalized and the amount of electrical energy passing through the rectifier 410 may be equalized (Ep1 = Ep2 = Ep3) to further increase the amount of electrical energy that can be stored in the storage device 400. The equalization of the output voltage according to the change of the electrode area may be equally applied to the piezoelectric, triboelectric charging, or liquid friction method of FIG. 2B, 2C, or 2D.
