Problems solved by technology

The external force generated by vibration does not have this characteristic, so there is no nanogenerator that absorbs vibration energy through sliding friction.

Embodiment

[0068]A sheet-like polyimide (Kapton) film is used as the first friction layer 11 , and a layer of copper film is deposited on its surface as the first electrode 21 to form a composite sheet of the friction layer and the electrode. By folding the film, the composite sheet is formed into a tooth-shaped first friction unit and fixed on the base made of copper-plated polymethyl methacrylate (PMMA) plate, so that the Kapton film becomes the core of the first friction unit. Outer surface; the first electrode is located at the center of each tooth structure after extrusion molding, and its fixed end that is in contact with the copper-plated side of the PMMA substrate is connected to the copper conductive thin layer with each other, thus completing the first component preparation. The second component is prepared in the same way, the only difference is that the second friction layer 21 and the second electrode 22 use the same material—aluminum foil. Therefore, it is only necessary t...

Abstract

The invention discloses a friction nanometer power generator with a gear shaping structure. The power generator mainly comprises two friction components which are connected through an elastic component, wherein at least one component is of the gear shaping structure which is formed by arranging a plurality of friction units; the gear shaping structure can form a tight occluding state with a friction unit on the other component; under the action of the elastic components, the relative position between the two components can be periodically changed by external force, so that a friction power generation process is promoted, and an electrical signal can be output outwards by the power generator. Effective extraction of vibration energy by sliding friction is realized for the first time through cooperation between the two friction units and the elastic components; meanwhile, through the occluding between first friction units and second friction units matched with the first friction units which are distributed in a gear shaping state, the area of sliding friction is increased, and the electricity output performance of the power generator is improved.

Description

technical field [0001] The invention belongs to the field of friction nanometer generators, in particular to a friction nanometer generator with a slotting structure. Background technique [0002] Since Professor Wang Zhonglin invented the first nanogenerator in 2006, nanogenerators have attracted widespread attention due to their characteristics of self-driving, small size, and effective collection of tiny mechanical energy. Revolutionary changes have been brought about in areas such as tiny energy harvesting. [0003] Nanogenerators are divided into two types: piezoelectric and electrostatic. Electrostatic nanogenerators are also called frictional nanogenerators. According to the contact mode of their friction surfaces, they are divided into contact-separation frictional nanogenerators and Sliding triboelectric nanogenerator. Among them, contact-separation friction nanogenerators are mainly used to absorb vibration energy and output electrical signals. The structure of ...
