Problems solved by technology

[0006]In addition, for triboelectric flexible materials, thin films with a thickness of microns are often used. In the previous contact-separation design, the thin film was directly exposed on the surface of the structure. In the external environment, it is easy to suffer from wear, tear and pollution, resulting in poor durability

Abstract

The invention designs a push-type friction nanometer generator capable of improving low-frequency output. Under low-frequency small-load push excitation of the device, through a structural design, the amplitude and frequency of an output voltage and current of the friction nanometer generator device are remarkably improved, meanwhile, key parts of the device are effectively protected structurally, the service life of the device is prolonged, and the thickness of the insulating spacer is properly designed so that the deformation of the spring steel sheet and the positive electricity conducting plate can be limited in a reasonable range, the damage of the conducting plate caused by overlarge deformation is avoided, and the service life of the device is prolonged; and generation of electric signals is based on the principle of triboelectrification and electrostatic induction, positive electricity materials and negative electricity materials are wide in selection, the overall structure is simple and labor-saving, and the production cost is low.

Description

technical field [0001] The invention belongs to the technical field of new energy power generation, and relates to a press-type friction nanometer generator for improving low-frequency output. Background technique [0002] When two different materials are in contact, their surfaces can generate positive and negative charges on the surface of the material due to different contact electrification effects. When the two materials are separated, an induced potential difference will be generated on the back electrode of the material. When the load is connected, The induced potential difference will generate a driving current, and the above is the basic principle of the triboelectric nanogenerator. This technology can provide energy for low-power electronic devices, and overcomes the shortcomings of frequent replacement and heavy pollution caused by traditional chemical batteries as energy sources. It is a key link that needs to be developed and improved in the field of the Interne...
