Embodiment Construction
[0024] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0025] like figure 1 and figure 2 As shown, an acoustic energy collector based on an embroidered stretch structure includes a triboelectric nanogenerator. The triboelectric nanogenerator includes a first electrode, a second electrode and a friction layer, and the friction layer is a FEP (Fluorinated ethylenepropylene) film 107 . The FEP film 107 is disposed between the first electrode and the second electrode, and both the first ele...

The present invention proposes an acoustic energy collector based on an embroidered stretch structure, which is used to solve the technical problems of low output performance, complex structure and high cost of the existing sound energy capture frictional nanogenerator. The present invention includes a frictional nanogenerator. The triboelectric nanogenerator includes a first electrode, a second electrode and a FEP film, the FEP film is arranged between the first electrode and the second electrode, and the first electrode and the second electrode are both supported by an embroidery stretcher assembly. Inspired by the embroidery tensioner of traditional Chinese embroidery equipment, the present invention uses the embroidery tensioner structure to tighten the two electrodes of the friction nanogenerator, which is exquisite in design, simple in structure, strong in portability, low in cost, and has excellent electrical output performance. Better capture of sound energy, very suitable for places with high noise such as airports, subway passages, construction sites, etc., very suitable for complex external environments in people's daily life, and can be arranged on a large scale and in multiple regions.
Description
technical field [0001] The present invention relates to the technical field of nanometer power generation, in particular to an acoustic energy collector based on an embroidered stretch structure. Background technique [0002] With the reduction of fossil fuels and the increasingly serious environmental pollution problems, the energy crisis is facing great challenges, and people are eager to find new, green and clean energy to replace fossil fuels. As one of the green energy in nature, sound energy is abundant, clean and widely distributed, and is an ideal green energy. Triboelectric nanogenerators utilize the coupling of triboelectricity and electrostatic induction to convert mechanical energy in the environment into electrical energy to power small electronic devices and IoT nodes. However, due to the low efficiency of sound energy harvesting, a variety of acoustic energy harvesting techniques have been tried in recent years to capture sound energy. Traditional sound ener...
