Problems solved by technology

However, the current widely used fixed power charging technology is difficult to meet the demand for charging mobile electronic devices anytime and anywhere
Although the emergence of mobile power sources such as "power bank" has alleviated the above problems to a certain extent, due to the fixed nature of mobile power charging, it is still difficult to completely solve the problem of charging mobile electronic devices anytime and anywhere.

preparation example Construction

[0014] Preparation of the first electrode layer 7: Take the aluminum sheet, chemically etch one end face of the aluminum sheet with hydrochloric acid with a concentration of 7% for 2 minutes, and then use 1H, 1H, 2H, 2H-perfluorodecane with a mass concentration of 0.8wt% The base trichlorosilane-toluene solution was modified at room temperature for 12h, and a self-assembled superhydrophobic polymer layer based on the aluminum matrix was formed on the end face of the aluminum sheet. The contact angle of water droplets on the surface of the superhydrophobic polymer layer could reach 151°. The superhydrophobic polymer layer is the second friction layer 13 . The rest of the aluminum flakes are used as electrodes. That is to say, the first electrode layer 7 serves not only as an electrode layer, but also as a friction layer carrier.

[0015] The second friction layer 13 is arranged face to face with the first friction layer 9 .

[0016] The elastic member 8 adopts a spring, prefe...

Embodiment 1

[0028] Cut an aluminum sheet with a diameter of 50mm and a thickness of 0.3mm, chemically etch and modify with 1H,1H,2H,2H-perfluorodecyltrichlorosilane, and form a self-assembled superhydrophobic layer based on an aluminum matrix on one end of the aluminum sheet. The molecular layer (that is, the second friction layer 13 ) is made into the first electrode layer 7 . Cut an elastic sponge with a diameter of 50mm and a thickness of 3mm, stick the first electrode layer 7 closely on the elastic sponge, and the second friction layer 13 is away from the elastic sponge; then cut the size to be 60mm×60mm×2mm (length, width and thickness) of the acrylic sheet, and reserve a spring connection hole with a diameter of 8mm at the four corners of the acrylic sheet, and then stick the acrylic sheet tightly to the other side of the elastic sponge. Cut a polydimethylsiloxane sheet with a diameter of 50mm and a thickness of 0.03mm, and paint a silver paste with a thickness of 0.1mm on the back ...

Abstract

The invention discloses a mobile phone self-charging system based on a friction nano-generator, which comprises an energy collection unit, a management circuit, an energy storage unit and a USB charging interface connected in sequence, wherein the energy collection unit comprises a first power generation component and a second power generation component which are connected through a plurality of elastic pieces; the first power generation component is composed of a first supporting layer, a first elastic layer and a first electrode layer which are sequentially bonded from top to bottom; the second power generation component is composed of a second supporting layer, a second elastic layer, a second electrode layer and a first friction layer which are sequentially bonded from bottom to top; the first supporting layer and the second supporting layer are connected through a plurality of elastic pieces; and a gap is formed between the first power generation component and the second power generation component. The mobile phone self-charging system has the advantages of simple structure, light weight, low cost, portability and the like. Mechanical energy of a human motion is effectively collected and converted into electric energy, and a mobile phone can be charged anytime and anywhere. And the limitation of power failure and remote mountainous areas on mobile phone charging is brokenthrough.

Description

technical field [0001] The invention belongs to the technical field of nano power generation and its application, and relates to a mobile phone self-charging system based on a friction nano generator. Background technique [0002] Mobile electronic devices such as mobile phones and tablet computers have played an indispensable role in people's lives. However, the currently widely used fixed power charging technology is difficult to meet the demand for charging mobile electronic devices anytime and anywhere. Although the emergence of mobile power sources such as "power bank" has alleviated the above problems to a certain extent, due to the fixed nature of mobile power charging, it is still difficult to completely solve the problem of charging mobile electronic devices anytime and anywhere. Therefore, the development of a new mobile phone self-charging system is an effective way to solve the above problems by converting the ubiquitous mechanical energy in nature into electric...
