Detailed Description
To further illustrate the technical means and effects of the present invention adopted to achieve the intended purpose of the invention, the following detailed description is given with reference to the accompanying drawings and preferred embodiments.
The utility model provides a flexible electronic components, this flexible electronic components when guaranteeing the bending performance, can provide better shock resistance for the circuit in the flexible electronic components.
Fig. 1 is a schematic view of a front view structure of a flexible electronic component according to a first embodiment of the present invention, and fig. 2 is a schematic view of a top view structure of the flexible electronic component shown in fig. 1. As shown in fig. 1 and 2, in a first embodiment of the present invention, a flexible electronic component includes a case 10 and a circuit 20 provided in the case 10, a meandering flow channel 30 is formed between the case 10 and the circuit 20, and a non-newtonian fluid 40 is filled in the flow channel 30.
In the present embodiment, since the meandering flow channel 30 is formed between the circuit 20 and the housing 10, and the non-newtonian fluid 40 is filled in the flow channel 30, since the deformation rate of the non-newtonian fluid 40 is in inverse function relationship with the generated reaction force, the larger the impact force applied to the non-newtonian fluid 40, the larger the generated force against the impact, and the non-newtonian fluid 40 assumes a meandering shape due to the presence of the meandering flow channel 30, as shown in fig. 2, in the plane where the flow channel 30 is located, if the flexible electronic component is subjected to the force in the extending direction of the meandering flow channel 30, the non-newtonian fluid 40 is subjected to the pressure applied to the side walls of the flow channel 30 in a plurality of directions due to the presence of the flow channel 30, the resistance of the non-newtonian fluid 40 is low, and the non-newtonian fluid 40 is deformed together with the flow channel 30, and therefore, in this direction, the non-newtonian fluid 40 does not exert, the non-newtonian fluid 40 does not significantly affect the tensile properties of the flexible electronic component in this direction; when the flexible electronic component receives a force perpendicular to the extending direction of the meandering flow channel 30 in the plane of the flow channel 30, the non-newtonian fluid 40 generates a large resistance to the force, and thus the circuit 20 can be protected against an impact on the circuit 20 inside the housing 10 in the extending direction perpendicular to the meandering flow channel 30; when the flexible electronic component receives a force in a direction perpendicular to the plane of the meandering flow channel 30, that is, in the Z direction, the force acts directly on the plane of the flow channel 30, and the non-newtonian fluid 40 also generates a large resistance to the force in the direction, so that the circuit 20 in the housing 10 can be protected in the Z direction. In summary, by arranging the flow channel 30 extending in a meandering manner and filling the non-newtonian fluid 40 in the flow channel 30, the resistance to the applied force can be generated in the plane of the flow channel 30, perpendicular to the extending direction of the flow channel 30 and perpendicular to the plane of the flow channel 30, so as to protect the circuit 20, while the extending direction of the flow channel 30 does not affect the stretching performance of the flexible electronic component, and meanwhile, because the non-newtonian fluid 40 has the flowing performance, the original performance of the circuit 20 is not affected in the slow bending and stretching process, so that the bending performance of the flexible electronic component itself can be ensured. The anisotropic protection mode can be applied to flexible electronic components which need to be stretched and deformed by a relatively large tensile force in one direction and need to protect the circuit 20 in other directions, such as flexible electronic components attached to joints of knees, elbows and the like.
Referring to fig. 1, in the present embodiment, the winding-extending flow channel 30 is disposed between the upper surface of the circuit 20 and the top surface of the housing 10, and/or between the lower surface of the circuit 20 and the bottom surface of the housing 10.
Further, in order to facilitate the arrangement of the flow path 30, in the present embodiment, a gasket layer 11 is further provided in the case 10, the circuit 20 is interposed between the upper and lower gasket layers 11, and the flow path 30 extending in a meandering manner is formed between the gasket layer 11 and the case 10. The middle structure can be manufactured by layering the circuit 20 and the gasket layer 11 in advance, and then assembling and placing the middle structure in the shell 10, which can simplify the manufacturing process.
With reference to fig. 2, in order to make the anisotropy of the flexible electronic component to the applied force more obvious in the present embodiment, the meandering flow channel 30 is in an undulate shape, and the undulated flow channel 30 extends in the same direction, for example, in fig. 2, the undulated flow channel 30 extends in the Y direction, that is, in the extending direction of the flow channel 30, when the applied force is applied, the flow channel 30 may stretch or contract along with the circuit 20, and the non-newtonian fluid 40 in the flow channel 30 may not generate a large resistance. In the X and Z directions, the non-newtonian fluid 40 is more resistant to the applied forces to protect the circuit 20.
In this embodiment, the circuit 20 may be made of a simple metal substance such as gold, silver, copper, platinum, or the like, or a liquid alloy such as gallium indium tin alloy, or an inorganic metal oxide such as ITO, AZO, or the like, or an organic conductive material such as PEDOT, conductive silver paste, structural conductive polymer (PAN \ PE, PPY \ PS), or a carbon-based conductive material such as graphene, carbon nanotube, or the like. The circuit 20 may be formed from the above-described materials by magnetron sputtering, CVD, PVD, 3D printing, and the like. The magnetron sputtering, CVD and PVD are standard semiconductor processes, and have the advantages of accurate preparation process, low cost, batch production and the like, and the 3D printing mode has the advantages of simple process, high reliability and the like.
The case 10 may be injection molded from organic polymers such as PDMS, PET, PE (polyethylene), polypropylene (PP), and Polyimide (PI), or hydrogel materials such as PLA (polylactic acid) and polyacrylamide.
The non-newtonian fluid 40 may be made of organic polymers such as polyethylene, polyacrylamide, polyvinyl chloride, nylon 6, PVS, celluloid, dacron, and rubber solution, or light industrial materials such as ceramic pulp, paper pulp, paint, and ink. The organic polymer solution, the ceramic slurry and the printing ink have adjustable performances such as fluidity, viscosity density and the like, and other functional materials or particles can be added, for example, a magnetic material is added to enable the organic polymer solution, the ceramic slurry and the printing ink to sense an external magnetic field.
As described above, in the present embodiment, the meandering flow channel 30 is formed in the housing 10, and the non-newtonian fluid 40 is filled in the flow channel 30, which enables the flexible electronic component to have anisotropy in resistance to the applied force, so that the flexible electronic component can maintain its tensile property in a specific direction while ensuring the bending property, but can well protect the circuit 20 in other specific directions.
Fig. 3 is a schematic structural diagram of a flow channel 30 in a flexible electronic component according to a second embodiment of the present invention, as shown in fig. 3, the flexible electronic component according to the second embodiment of the present invention is basically the same as that provided in the first embodiment, and the difference is that, in this embodiment, the flow channel 30 extending in a meandering manner is not in a wave shape, as shown in fig. 3, for easy understanding, a line is used in fig. 3 to replace the flow channel 30 to simplify the shape of the flow channel 30, and the shape of the flow channel 30 may also be in a square waveform shape.
It will be appreciated that in other embodiments, the serpentine extending flow passage 30 may also be, but is not limited to, serpentine, saw tooth, sinusoidal, S-shaped, etc., as long as it exhibits a serpentine extending extension.
Fig. 4 shows the structure diagram of the flow channel 30 in the flexible electronic component provided by the third embodiment of the present invention, as shown in fig. 4, the flexible electronic component provided by the third embodiment of the present invention is basically the same as the first embodiment, and the difference lies in that, in this embodiment, the flow channel 30 extending in a meandering manner is extended in a self-similar shape, taking a self-similar square waveform as an example, and in the Y direction of the self-similar square waveform, i.e., in fig. 4, a graph similar to the whole square waveform can be cut off in the vertical direction (see fig. 4 in a dashed frame), so that the flow channel 30 extends in a meandering manner, and meanwhile, the anisotropy of the flexible electronic component to the acting force can also be adjusted according to actual conditions. As shown in fig. 4, the sheet has a meandering shape in the Y direction, and therefore has a certain tensile property in the Y direction, and also has a good impact resistance under a relatively strong force due to the presence of the non-newtonian fluid 40.
It is understood that the serpentine flow channel 30 can be, but is not limited to, a self-similar serpentine shape, a self-similar zigzag shape, a self-similar wave shape, etc.
Further, the self-similar shape of the meandering flow channel 30 may be an N-order self-similar shape (N is a positive integer), that is, in a part of the original pattern, the self-similar shape may be further refined into a plurality of patterns similar to the original pattern, as shown in fig. 4, in a part of the original pattern, such as a rectangular frame, a pattern similar to the original pattern may be refined, and thus, may be referred to as a second-order self-similar pattern.
In summary, in the present invention, the flow channel extending in a meandering manner is formed in the housing, and the flow channel is filled with the non-newtonian fluid, so that the flexible electronic component has anisotropy against the acting force, and the flexible electronic component maintains its tensile property in a specific direction while ensuring the bending property, but can better protect the circuit in other specific directions.
The above description is only a preferred embodiment of the present invention, and the present invention is not limited to the above embodiments, and although the present invention has been disclosed with the preferred embodiments, it is not limited to the present invention, and any skilled person in the art can make some modifications or equivalent changes without departing from the technical scope of the present invention.
