Problems solved by technology

On the one hand, due to the deposition of metal, the production cost of this generator is relatively high; on the other hand, the thickness of the friction material must be within a certain range.
These limiting factors have greatly hindered the popularization and application of triboelectric nanogenerators.

Embodiment 1

[0117] Example 1: Preparation of triboelectric nanogenerator

[0118] Use a laser to cut two plexiglass plates with a length of 3cm × width 3cm × thickness 1.59mm, deposit a layer of Al on the back of the polyolefin electret sheet with the same area as an electrode layer, and lead it out through a wire and pass through a monitoring element and then ground , and then stick it on a plexiglass plate to expose the polyolefin surface; stick a piece of Al foil on another plexiglass plate so that the Al foil is opposite to the polyolefin surface. The contact and separation between the Al foil and the polyolefin surface is controlled by external force, and the monitoring element displays an electrical signal output. Figure 18 -a is the open circuit voltage diagram, Figure 18 -b is the short-circuit current density signal.

Abstract

The present invention discloses a friction nanometer generator, a generating set and a power generation method. The generator comprises a first frictional layer, an electrode layer attached to the lower surface of the first frictional layer and a second frictional layer, at least parts of the surfaces of the first and second frictional layers can be contacted and separated under the effects of external forces, at the same time, the electrode layer and a first equipotential source output the electric signals. The friction nanometer generator of the present invention only has one electrode layer, and has the characteristics of low cost, high efficiency, simple structure, etc. In an optimized scheme, an electret is used as a frictional layer, thereby improving the output efficiency of the electric signals substantially, and realizing the situation for the first time that the single small-size contact and separation type friction nanometer generator lightens the LED lamps.

Description

technical field [0001] The invention relates to a generator, in particular to a friction nanometer generator, a generator set and a power generation method. 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 limiting factors have greatly hindered the popularization and application of triboelectric nanogen...
