Embodiment 1

[0025] The embodiment of the present invention discloses a power generation unit, such as figure 1 As shown, it includes: a base ball cavity 1, an elastic ball 2, a first electrode 31 and a second electrode 32; the first electrode 31 and the second electrode 32 are arranged oppositely and placed on the inner wall of the base ball cavity 1; The ball 2 is placed in the cavity 1 of the base ball.

[0026] It should be understood that the embodiment of the present invention mainly utilizes triboelectrification (that is, when two objects are in contact with each other, the surface of one object loses or acquires electric charges, and the other object obtains or loses an equal amount of electric charges) and electrostatic induction Principle, the power generation method that converts tiny vibration energy in the environment into electric energy, its main advantages are high output voltage and low production cost (ordinary electrification materials are enough). Especially compared w...

[0029] Based on the above technical solution, the power generation units are arranged in layers to greatly improve the overall power generation effect.

[0030] In order to further optimize the above-mentioned technical scheme, such as figure 2 As shown, the first electrode 31 is connected to the first electrode 31 of the adjacent power generation unit, while the second electrode 32 is connected to the second electrode 32 of the adjacent power generation unit.

[0031] In order to further optimize the above-...

Embodiment 3

[0033] The embodiment of the invention discloses a monitoring sensor, which includes a periodic cavity structure-based friction power generation device and an oscilloscope; the oscilloscope is respectively connected to the two poles of the friction power generation device.

[0034] Based on the three-dimensional periodic arrangement of the power generation units in the power generation device, the overall power generation system forms a passband and bandgap structure. The passband structure can be used to detect waves in a certain frequency range. The specific frequency range of the wave is based on the basis of the power generation unit. The size of the spherical cavity; the bandgap structure can prevent the propagation of waves in a certain frequency range, and the specific frequency range of the wave is also determined according to the size of the base spherical cavity of the power generation unit; the frequency of the wave is detected by an oscilloscope or other detection de...

Description

technical field [0001] The invention relates to the technical field of power generation, and more specifically relates to a friction power generation unit based on a periodic cavity structure, a power generation device, a monitoring sensor and an expandable platform. Background technique [0002] The existing methods of collecting vibration energy include the traditional piezoelectric type and the newly emerging power generation technology based on the principle of friction electrification in recent years. [0003] The principle of the piezoelectric energy harvester is that the vibration of the piezoelectric structure drives the vibration of the piezoelectric structure to generate polarized charges for power generation. It has the advantages of high energy density, simple structure, easy processing and production, and miniaturization and integration. However, its main disadvantages are Resonance of the structure is required to have a large energy output, and the output volta...
