Problems solved by technology

A large amount of power consumption makes it difficult for these existing tracking systems to be widely used in the future energy crisis. The development of a self-driven tracking system is fundamentally the key to solving the long-term and stable work of these devices

Embodiment 1

[0118] Example 1: Preparation of surrounded single-electrode triboelectric nanogenerator

[0119] A plexiglass plate with a length of 3 cm x a width of 3 cm x a thickness of 1.59 mm was cut by a laser as the second supporting element, and a piece of Al foil was used to cover the plexiglass plate. A piece of nylon film with a length of 7 cm × width of 3 cm × a thickness of 25 μm and a piece of polyimide with a length of 7 cm × width of 3 cm × thickness of 127 μm were pasted together with adhesive tape. The surface of the nylon faces the Al foil, and its two ends are symmetrically fixed on the upper and lower surfaces of the plexiglass with adhesive tape to form an elastic cavity (see Figure 15 ). Connect the Al foil with a copper wire, and connect it to a resistor, and the other end of the resistor is grounded. Due to the good elasticity of the polyimide film, it can be ensured that the nylon film and the Al foil are completely separated without pressure. When compressed, t...

[0120] Example 2: Preparation of a single-electrode tribogenerator

[0121]A plexiglass plate with a length of 10 cm x a width of 10 cm x a thickness of 1.59 mm was cut by laser as the second supporting element, and a Cu film of 10 cm x 2 cm x 0.5 mm was prepared on the mirror-symmetrical parts of its upper and lower surfaces. Take another two polystyrene sheets of 10cm×3cm×1mm as the friction layer, and fix the two ends of each piece symmetrically on the upper and lower surfaces of the plexiglass, so that the polystyrene sheet is bent to form a cavity, and the polystyrene A vinyl sheet is overlaid right on top of the Cu film. Each Cu film is connected by a wire and a resistor grounded at one end to form a generator set with 2 generators, the structure of which is the same as Figure 11 The illustrated embodiment is similar. Due to the high elasticity of polystyrene, it can be ensured that the polystyrene flakes and Cu film are completely separated without pressure. When co...

[0123] Example 3: Preparation of a single-electrode triboelectric generator tracking device

[0124] Make 16 friction generators of the same size according to the method of Example 1, and arrange them in a matrix of 4×4, the circuit connection of the whole generating set is as follows Figure 17 -a shown. The difference from Example 1 is that the first component is aluminum foil, and the second component is a polytetrafluoroethylene plate. When the object moves in the tracking system, the contact between the object and the friction generator will cause the compression of the generator, thereby outputting an electrical signal. Through the collection of these signals, the detection of the moving path of the object can be realized. The system directly uses the friction generator as a trigger sensor, does not require external power supply, can effectively save energy, and can work stably for a long time. Figure 17 -b is a real photo of the tracking system made. When we compre...

Abstract

Disclosed are a surrounding-type single-electrode frictional nanometer generator, a power generation method and a tracking device. The single-electrode frictional generator is formed according to the principle that polymer materials and metal materials have different frictional electricity properties, and a tracking system based on the generator is produced. The tracking system is an array matrix formed by a plurality of generator units; when an object moves on the tracking system, pressure acts on the generator to cause contact between two layers of frictional electricity materials of the generator, and electric signals are output to the outside; when the object leaves the generator, the two layers of frictional electricity materials constituting the generator are separated from each other due to the action of elastic materials, and the electric signals are also output to the outside. The tracking system based on the frictional generator can track moving paths of some objects, and has the advantages of low cost, automatic drive, simple structure and the like.

Description

technical field [0001] The invention relates to a frictional nanometer generator, in particular to an enclosed single-electrode frictional nanometer generator, a generator set, a power generation method and a tracking device based on the generator. Background technique [0002] The working principle of the triboelectric nanogenerator is based on the mutual contact and separation between two materials with different triboelectric properties to generate electricity. However, all triboelectric nanogenerators currently reported require two electrode layers, at least one of which needs to be formed by depositing conductive metal on the surface of the tribofilm material, and the external electrical energy is realized through these two electrode layers. output. On the one hand, the deposition of metals in this kind of generator leads to high manufacturing cost of the device, and on the other hand, the thickness of the friction material must be within a certain range. These limiti...
