Embodiment 1

[0056] A preferred embodiment of the present invention provides a wind chime type friction nanogenerator, comprising a packaging cavity 1 and a swing unit arranged in the packaging cavity 1;

[0057] The encapsulation cavity 1 is provided with a vent 101, and an electrode 2 is provided inside, and the electrode 2 includes an electrode layer 201 disposed oppositely on the two inner surfaces of the encapsulation cavity 1;

[0058] The swing unit includes a swing film 3 and a friction film. One end of the swing film 3 is connected to the top of the packaging cavity 1, and the other end is connected to the friction film to drive the friction film to swing. The friction film can be in contact with the electrode layer 2 during the swing process. .

[0059] Further, the friction film is a hollow cylinder friction film 4, the hollow cylinder friction film 4 is a cylinder formed by curling a rectangular film, and the material is a flexible organic polymer film material with friction ne...

Embodiment 2

[0079] In this embodiment, on the basis of Embodiment 1, further, a circular film 401 of PTFE material with a diameter of 2.5 cm is provided at the bottom circle of the hollow cylindrical friction film 4, facing the left side and the left side of the packaging cavity 1. Right.

[0080] Furthermore, the electrode 2 also includes electrode sheets 202 arranged on the other two inner surfaces of the packaging cavity 1, specifically arranged on both sides perpendicular to the axial direction of the hollow cylindrical friction film 4, and the height is the same as that of the circular film (401), etc. High, the electrode sheet 202 is a circular aluminum foil electrode with a diameter of 2.5 cm, located on the left and right sides of the packaging cavity 1, and two are arranged on one side, such as Figure 4 , Figure 5 shown.

[0081] Furthermore, the step 1 also includes sticking a circular film 401 of PTFE material with a diameter of 2.5 cm on the two bottom circles of the hollo...

Abstract

The invention discloses a wind bell type friction nano-generator and a manufacturing method thereof, which belong to the technical field of self-energy supply. The wind bell type friction nano-generator includes a packaging chamber and a swing unit arranged in the packaging chamber. The packaging chamber is provided with an air vent thereon and an electrode therein. The electrode includes electrode layers oppositely arranged on the two inner surfaces of the packaging chamber. The swing unit includes a swing film and a friction film. One end of the swing film is connected with the top of the packaging chamber, and the other end is connected with the friction film to drive the friction film to swing. The friction film can contact the electrode layer during swing. The weak wind energy in theenvironment or the micro energy of human respiratory airflow can be fully converted into electrical signals and output, and the problem that the existing friction nano-generator is limited in usage scenario and cannot collect small wind energy is solved.

Description

technical field [0001] The invention belongs to the technical field of self-supply, relates to the technical fields of energy collection, clean energy and self-supply, in particular to a wind chime type frictional nanometer generator and a manufacturing method thereof. Background technique [0002] Whether it is industrial equipment, household electricity or miniaturized portable electronic equipment, it is inseparable from the supply of electric energy. With the increasingly serious problem of energy shortage, it is urgent to develop new energy harvesting technologies to realize the collection of daily clean energy, such as wind energy, human motion mechanical energy or ocean energy. This kind of clean energy has many advantages such as abundant storage, wide distribution, and huge scale. , but are often ignored. [0003] Existing new energy technologies, such as solar energy and fuel cells, can solve the problem of energy shortage to a certain extent, but solar technology...
