The present invention relates to a triboelectric energy generating device, and more particularly, to a multiphase triboelectric energy generating device capable of generating polyphase electricity by friction.

Unlike conventional solar cells, wind power, fuel cells, etc., triboelectric energy power plants have a new concept of eco-friendly technology that can extract the mechanical energy of consumptions generated from human vibrations and human vibrations infinitely It corresponds to the energy generation element. The energy conversion method using the electrostatic induction phenomenon is considered to be a new technology leading to a breakthrough of technology through convergence with nanotechnology, which can be made compact and lightweight with high conversion efficiency, and is evaluated as a technology having a large ripple effect on the application field have.

Conventional triboelectric energy generation devices that harvest energy using electrostatic induction phenomenon generate triboelectricity due to potential difference due to displacement difference caused by electrostatic induction phenomenon generated from friction material. As a result, the triboelectricity that occurs is generated and disappears for a short period of microseconds in the form of alternating current (AC), and therefore there is a time difference until friction occurs again. Therefore, the use of such triboelectricity can not continuously drive the electric or electronic devices, and even when the generated triboelectricity is stored in the charger, the storage efficiency is lowered.

However, if the conductive material is conductive, the plurality of electrodes 1100a, 1100b, and 1100c , 1100d, ... 1100n are not limited to the materials listed above.

The friction member 1200 may frictionally contact the plurality of electrodes 1100a, 1100b, 1100c, 1100d, ... 1100n and the friction member 1200 may include a plurality of electrodes 1100a, 1100b, 1100c, 1100d, ... 1100n And a portion of the other one of the electrodes adjacent to each other.

The multiphase frictional electric energy generating device 3000 according to another embodiment of the present invention may be configured such that the first substrate 3100 and the third substrate 3700 rotate at the same time or the second substrate 3400 can rotate Such rotation may cause friction. Such friction may cause polyphase triboelectricity.

Referring to FIG. 9, a third substrate 3700 of a polyphase triboelectric energy generating device 3000 is stacked to laminate a polyphase triboelectric energy generating device 3000 according to another embodiment of the present invention The multiphase triboelectric energy generating device 3000 having the laminated structure can be constructed by using the first substrate 3100 of the other polyphase triboelectric energy generating device 3000, have. Further, a polyphase friction electric energy generating device 3000 having a laminated structure may be constructed by stacking polyphase friction electric energy generating devices 3000 according to another embodiment of the present invention.

10 is a graph showing the triboelectricity of a polyphase friction electric energy generating device according to an embodiment of the present invention.

Referring to FIG. 10, it can be seen that as the phase of the generated triboelectricity increases, the phase difference between the triboelectric currents generated decreases. Therefore, in order to continuously generate polyphase triboelectricity, the number of electrodes used in the polyphase triboelectric energy generating device according to the embodiment of the present invention is increased and the number of friction members is also increased corresponding to the increase in the number of electrodes desirable.
