Abstract

The invention provides a friction nanometer generator with an elastic structure. The friction nanometer generator comprises an elastic bases, a plurality of generating units and a mass block, wherein the elastic base is an s-shaped and bent multi-layer folding structure; two layers of adjacent bases are mutually connected to form a V-shaped or U-shaped sunken structure; a generating unit comprises a first friction unit and a second friction unit in face to face, and the first friction unit and the second friction unit are respectively arranged on two layers of adjacent bases; the mass block vibrations up and down under the vibration energy effect; the first friction unit and the second friction unit are mutually contacted and separated under the effect of the elastic base; and an electric signal is generated between the electrode of the first friction unit and the electrode of the second friction unit. The parallel connection of multiple generator units are realized on a support structure of the elastic substrate, and the optimal output frequency range of the generator is adjusted by adjusting the mass block, and the environment vibration energy can be converted into electric energy in the low frequency range of 3-30 hz.

Description

technical field [0001] The invention relates to the field of energy conversion, in particular to a friction nanogenerator which collects environmental vibration energy in a wide frequency range. Background technique [0002] In recent years, wireless sensor networks have developed rapidly and are widely used in the fields of environment, safety, process control and health monitoring, improving the utilization efficiency of resources and realizing the intelligence of natural environment and engineering control. However, a large number of wireless sensor nodes also brings some urgent problems, especially the demand for energy. With the development of science and technology, although the performance of battery technology has been greatly improved, it still cannot keep up with the growth rate of energy demand of wireless sensors. As a kind of mechanical energy ubiquitous in the natural environment, vibration energy is less restricted by external conditions and convenient to col...
