Detailed Description

Embodiments of the present disclosure are disclosed below with reference to the accompanying drawings, and for the purposes of explanation, numerous specific details are set forth in the description below. It should be understood, however, that these implementation details should not be used to limit the disclosure. That is, in some embodiments of the disclosure, such implementation details are not necessary. In addition, for the sake of simplicity, some conventional structures and elements are shown in the drawings in a simple schematic manner.

The first elastic waterproof film and the second elastic waterproof film of the elastic conductive module disclosed by the invention are respectively provided with a first arc-shaped part and a second arc-shaped part, the included angle between the extension direction of the elastic conductive module and the connection section of the arc center of the first arc-shaped part and the arc center of the second arc-shaped part is 25-35 degrees, and the first elastic conductive pattern is conformally clamped between the first elastic waterproof film and the second elastic waterproof film. Through the configuration, the elastic conductive module has good stretching capacity, so that the foreign body feeling brought by the elastic conductive module configured on the surface of a carrier (such as clothes) is reduced.

Fig. 1 is a schematic top view illustrating an elastic conductive module 100 according to an embodiment of the disclosure. Fig. 2 is an exploded view of the elastic conductive module 100 of fig. 1. Referring to fig. 1 and 2, the elastic conductive module 100 includes a first elastic waterproof film 110, a second elastic waterproof film 120, and a first elastic conductive pattern 130. Second elastic waterproof film 120 is conformably disposed on first elastic waterproof film 110, and first elastic conductive pattern 130 is conformably sandwiched between first elastic waterproof film 110 and second elastic waterproof film 120. In some embodiments, the first elastic waterproof film 110, the second elastic waterproof film 120 and the first elastic conductive pattern 130 may be formed by screen printing or coating.

It should be understood that "conformably clamped (configured)" herein refers to clamped (configured) in similar but not exactly the same shape (e.g., clamped (configured) in the same profile), while "conformally configured" refers to configured in exactly the same shape. In addition, when the elastic conductive module 100 of the present disclosure is disposed on the surface of the carrier, the first elastic waterproof film 110 is disposed to contact the surface of the carrier, and the second elastic waterproof film 120 is disposed not to contact the surface of the carrier.

In some embodiments, the second elastic waterproof film 120 extends along a first direction D1 and bends back and forth along a second direction D2, wherein the first direction D1 and the second direction D2 are perpendicular to each other. Specifically, the second elastic waterproof membrane 120 has a first arc-shaped portion 120a and a second arc-shaped portion 120b, and the first arc-shaped portion 120a and the second arc-shaped portion 120b are alternately arranged along the first direction D1. In other words, each first arc portion 120a is disposed between two adjacent second arc portions 120b in the first direction D1, and each second arc portion 120b is disposed between two adjacent first arc portions 120a in the first direction D1.

In some embodiments, the first arc 120a and the second arc 120b can have the same shape. For example, the first arc-shaped portion 120a and the second arc-shaped portion 120b may be C-shaped, for example. In some embodiments, the arc openings of the first arc 120a and the second arc 120b may face different orientations. For example, the arc openings of the first arc-shaped portion 120a and the second arc-shaped portion 120b face two opposite directions in the second direction D2. In addition, the first arc-shaped portion 120a and the second arc-shaped portion 120b are connected to each other. For example, the first arc portion 120a and the second arc portion 120b can be connected to each other through the respective arc ends.

In some embodiments, an angle θ between a line connecting the arc center O1 of the first arc portion 120a and the arc center O2 of the second arc portion 120b and the first direction D1 is between 25 ° and 35 °. By designing the included angle θ within this range, the flatness of the second elastic waterproof film 120 can be maintained, and the foreign substance sensation caused when the elastic conductive module 100 is disposed on the surface of the carrier can be reduced. In detail, if the included angle θ is designed to be less than 25 °, the outer edge 125a of the adjacent first arc-shaped portion 120a and/or the outer edge 125b of the adjacent second arc-shaped portion 120b are easily contacted or pressed with each other, which may cause the first arc-shaped portion 120a and/or the second arc-shaped portion 120b to be twisted or overlapped with each other, thereby affecting the flatness of the second elastic waterproof membrane 120; if the included angle θ is designed to be larger than 35 °, the width of the second elastic waterproof film 120 in the second direction D2 is too large, so that the foreign substance sensation caused when the elastic conductive module 100 is disposed on the surface of the carrier is increased. By designing the included angle θ, a first gap G1 is formed between the outer edges 125a of the adjacent first arc-shaped portions 120a, and a second gap G2 is formed between the outer edges 125b of the adjacent second arc-shaped portions 120 b.

In some embodiments, the ratio of the respective radii of curvature R1 and R2 of the first arc-shaped portion 120a and the second arc-shaped portion 120b to the width W of the first elastic conductive pattern 130 may be between 0.09 and 0.43. By designing the ratio of the radii of curvature R1 and R2 to the width W in this range, the magnitude of extension of the second elastic waterproof film 120 on the plane formed by the first direction D1 and the second direction D2 can be controlled. In detail, if the ratio of the curvature radii R1 and R2 to the width W is designed to be less than 0.09, the extent of the first arc-shaped portion 120a and/or the second arc-shaped portion 120b extending on the plane formed by the first direction D1 and the second direction D2 is too small, so as to increase the difficulty of manufacturing the elastic conductive module 100; if the above ratio is designed to be greater than 0.43, the extension of each of the first arc portion 120a and/or the second arc portion 120b in the plane formed by the first direction D1 and the second direction D2 is too large, so as to increase the foreign body sensation caused by disposing the elastic conductive module 100 on the surface of the carrier.

In some embodiments, the second elastic waterproof membrane 120 has two end portions 120c, and the two end portions 120c may be connected to the first arc portion 120a and/or the second arc portion 120b of the end, respectively. For example, one of the end portions 120c may be connected to the first arc portion 120a of one of the ends, and the other end portion 120c may be connected to the second arc portion 120b of the other end; alternatively, the two end portions 120c may be connected to the first arc portions 120a of the two ends, respectively; alternatively, the two end portions 120c may be connected to the second arc portions 120b of the two ends, respectively.

In some embodiments, first elastic conductive pattern 130 is conformably configured on first elastic waterproofing membrane 110. In detail, the first elastic conductive pattern 130 includes a plurality of first conductive paths 132, and the first conductive paths 132 have the same profile as the second elastic waterproof film 120. In other words, the first conductive via 132 also extends along the first direction D1 and bends back and forth along the second direction D2. In some embodiments, the first conductive vias 132 are spaced apart from each other in a plane formed by the first direction D1 and the second direction D2. In addition, the base material of the first elastic conductive pattern 130 may be conductive silver paste or conductive carbon paste, so that the first elastic conductive pattern 130 has good stretching ability.

In some embodiments, the elastic conductive module 100 further includes a plurality of first conductive contacts 140. The first conductive contacts 140 are disposed at two ends of the first conductive vias 132 in the first direction D1, so as to be electrically connected to an external electronic component. For example, each of the two ends of the first conductive vias 132 in the first direction D1 may be connected to one first conductive contact 140, i.e. the number of the first conductive contacts 140 is twice as many as the number of the first conductive vias 132. In some embodiments, the first conductive contacts 140 are spaced apart from each other in the second direction D2. In some embodiments, the first conductive contact 140 can be formed simultaneously with the first elastic conductive pattern 130 by screen printing or coating.

In some embodiments, since second elastic waterproof film 120 is conformably disposed on first elastic waterproof film 110, first elastic waterproof film 110 also has first arc portion 110a, second arc portion 110b and two terminal portions 110c. The first arc part 110a, the second arc part 110b and the two terminal parts 110c of the first elastic waterproof membrane 110 are respectively arranged in the same way as the first arc part 120a, the second arc part 120b and the two terminal parts 120c of the second elastic waterproof membrane 120, and thus the description is omitted. In some embodiments, the end portion 110c of the first elastic waterproof film 110 is configured to carry the first conductive contact 140, and a length L1 of the end portion 110c of the first elastic waterproof film 110 in the first direction D1 is greater than a length L2 of the end portion 120c of the second elastic waterproof film 120 in the first direction D1. In this way, the first conductive contact 140 can be exposed from the end portion 120c of the second elastic waterproof film 120, so as to be electrically connected to an external electronic component. In some embodiments, the base material of each of the first elastic waterproof membrane 110 and the second elastic waterproof membrane 120 is polyurethane (TPU). Since the first elastic waterproof film 110 and the second elastic waterproof film 120 have the same base material, the compatibility between the first elastic waterproof film 110 and the second elastic waterproof film 120 can be improved, thereby improving the structural stability and the manufacturing convenience of the whole elastic conductive module 100.

The elastic conductive module 100 has good stretching ability due to the shapes, the included angle θ, and the curvature radii R1 and R2 of the first elastic waterproof film 110, the second elastic waterproof film 120, and the first elastic conductive pattern 130, so that the foreign body sensation caused by disposing the elastic conductive module 100 on the surface of the carrier is reduced. In some embodiments, the maximum length of the elastic conductive module 100 in the stretched state is 1.2 times to 2 times of the length in the natural state. In some embodiments, when the elastic conductive module 100 is stretched to 1.2 to 2 times the length in the natural state, the rate of change of the resistance of the elastic conductive module 100 is between 20% and 50%.

Fig. 3 illustrates a partially enlarged view of the first elastic waterproof membrane 110 of fig. 2. Referring to fig. 2 and 3, the first elastic waterproof film 110 includes a first film layer 112 and a second film layer 114, and the second film layer 114 is disposed between the first elastic conductive pattern 130 and the first film layer 112. Since the elastic conductive module 100 is fixed to the surface of the carrier through the first film layer 112 of the first elastic waterproof film 110, the first film layer 112 of the first elastic waterproof film 110 is an adhesive layer that can be adhesive after being heated.

Fig. 4 is a cross-sectional view of the elastic conductive module 100 of fig. 1 along a line a-a'. Referring to fig. 2 and 4, the second elastic waterproof membrane 120 is further embedded between the first conductive channels 132 and connected to the first elastic waterproof membrane 110, such that the adjacent first conductive channels 132 are completely separated to ensure that the adjacent first conductive channels 132 are insulated from each other. In some embodiments, the elastic conductive module 100 further includes a release film 150. The release film 150 is detachably disposed on the surface of the first elastic waterproof film 110 opposite to the first elastic conductive pattern 130. In some embodiments, the release film 150 is conformally disposed on the surface of the first elastic waterproof film 110 opposite to the first elastic conductive pattern 130. Since the base material of the release film 150 is relatively rigid, the elastic conductive module 100 can be conveniently moved to the surface of the carrier to be configured after the fabrication through the configuration of the release film 150. It should be understood that the release film 150 is removed before the elastic conductive module 100 is fixed to the surface of the carrier.

FIG. 5 is a schematic top view of an elastic conductive module 200 according to another embodiment of the disclosure. Fig. 6 is an exploded view of the elastic conductive module 200 shown in fig. 5. Referring to fig. 5 and 6, the elastic conductive module 200 includes a first elastic waterproof film 210, two layers of second elastic waterproof films 220' and 220", a first elastic conductive pattern 230, a first conductive contact 240, a release film 250, a second elastic conductive pattern 260, and a second conductive contact 270. In other words, the elastic conductive module 200 of fig. 5 is different from the elastic conductive module 100 of fig. 1 in that the elastic conductive module 200 of fig. 5 has two layers of second elastic waterproof films 220' and 220 ″ and further includes a second elastic conductive pattern 260. In some embodiments, first elastic waterproof film 210, second elastic waterproof film 220', and second elastic waterproof film 220 ″ are sequentially stacked in a third direction D3, first elastic conductive pattern 230 is conformably sandwiched between first elastic waterproof film 210 and second elastic waterproof film 220', and second elastic conductive pattern 260 is conformably sandwiched between second elastic waterproof film 220' and second elastic waterproof film 220 ″, wherein third direction D3 is perpendicular to first direction D1 and second direction D2.

In some embodiments, the second elastic conductive pattern 260 includes a plurality of second conductive vias 262, and the second conductive vias 262 extend along the first direction D1 and bend back and forth along the second direction D2. In addition, the second conductive paths 262 are spaced apart from each other on a plane formed by the first direction D1 and the second direction D2. In addition, the base material of the second elastic conductive pattern 260 may be conductive silver paste or conductive carbon paste, so that the second elastic conductive pattern 260 has good stretching ability. In some embodiments, the second conductive contacts 270 are disposed at two ends of the second conductive vias 262 in the first direction D1 to further form an electrical connection with an external electronic component. For example, each of the two ends of the second conductive vias 262 in the first direction D1 may be connected to a second conductive contact 270, i.e. the number of the second conductive contacts 270 is twice as many as the number of the second conductive vias 262. In some embodiments, the second conductive contacts 270 are spaced apart from each other in the second direction D2. In some embodiments, the second conductive contact 270 may be formed simultaneously with the second elastic conductive pattern 260 by screen printing or coating.

It should be understood that, since the configuration of the components in the elastic conductive module 200 of fig. 5 is substantially the same as the configuration of the components in the elastic conductive module 100 of fig. 1, the description thereof is omitted here. The differences between the elastic conductive module 200 and the elastic conductive module 100 will be further described below.

In some embodiments, both ends of the second elastic waterproof film 220' in the first direction D1 may each have two end portions 220c1' and 220c2', and the two end portions 220c1' and 220c2' are adjacently arranged in the second direction D2. In detail, one of the end portions 220c1 'is configured to cover a portion of the first conductive contact 240, and the other end portion 220c2' is configured to carry the second conductive contact 270. A length L3 of the end portion 220c1 'of the first conductive contact 240 configured to cover the portion in the first direction D1 is less than a length L4 of the end portion 220c2' configured to carry the second conductive contact 270 in the first direction D1. In other embodiments, both ends of the second elastic waterproof film 220 'in the first direction D1 may have only one end portion 220c1', respectively, and both ends of the first elastic waterproof film 210 in the first direction D1 may have two end portions 210c, respectively. In detail, one of the end portions 210c is configured to carry the first conductive contact 240, and the other end portion 210c is configured to carry the second conductive contact 270, and the lengths of the two end portions 210c in the first direction D1 may be the same.

FIG. 7 is a cross-sectional view of the elastic conductive module 200 along the line b-b' of FIG. 5. Referring to fig. 6 and 7, the second elastic waterproof membrane 220 ″ is further inserted between the second conductive paths 262 and connected to the second elastic waterproof membrane 220', and the second elastic waterproof membrane 220' is further inserted between the first conductive paths 232 and connected to the first elastic waterproof membrane 210. As such, the adjacent first conductive vias 232 and the adjacent second conductive vias 262 are completely separated, so as to ensure that the adjacent first conductive vias 232 and the adjacent second conductive vias 262 are insulated from each other. In some embodiments, the release film 250 is detachably disposed on the surface of the first elastic waterproof film 210 opposite to the first elastic conductive pattern 230 and the surface of the second elastic waterproof film 220' opposite to the second elastic conductive pattern 260.

By sandwiching the plurality of elastic conductive patterns between the plurality of elastic waterproof films, respectively, the number of conductive paths included in the elastic conductive module 200 per unit area can be increased. In detail, when a plurality of conductive vias are stacked in the vertical direction (i.e., the third direction D3), the area of the elastic conductive module 200 in the horizontal plane (i.e., the plane formed by the first direction D1 and the second direction D2) is not affected. In this way, the foreign body sensation caused when the elastic conductive module 200 including a plurality of conductive channels is disposed on the surface of the carrier can be reduced. In addition, since the elastic conductive module 200 has relatively many conductive paths, a part of the conductive paths can be used as a spare circuit, so that the elastic conductive module 200 cannot be used continuously due to a failure of a part of the conductive paths.

Fig. 8A to 8C are schematic configuration diagrams illustrating the elastic conductive module 100 of the present disclosure disposed on a clothing carrier 300. As shown in fig. 8A to 8C, apparel carrier 300 may be, for example, pants, and fig. 8A to 8C sequentially illustrate a front schematic view, a side schematic view, and a rear schematic view of apparel carrier 300. Referring to fig. 8A to 8C, the electronic device 310 may be disposed in different areas of the clothing carrier 300 for signal measurement. For example, electronic components 310 may be disposed on apparel carrier 300 on the front thigh side (as shown in FIG. 8A), the outer thigh side (as shown in FIG. 8B), the outer calf side (as shown in FIG. 8B), the rear calf side (as shown in FIG. 8C), and the back waist (as shown in FIG. 8C). In addition, the electronic component 310 may be, for example, a muscle deformation sensor, a 9-axis multifunctional position sensor, or a controller. In some embodiments, a controller may be disposed at the back waist to control other electronic components 310 disposed on apparel carrier 300.

In some embodiments, the elastic conductive module 100 is disposed on the clothing carrier 300 to electrically connect the electronic elements 310. As shown in fig. 8A to 8C, the elastic conductive module 100 is sequentially extended from the controller to the outer thigh, the front thigh, the outer calf, the rear calf, and the outer calf to electrically connect the electronic components 310 disposed in the respective regions of the clothing carrier 300. Since the elastic conductive module 100 of the present disclosure has a good stretching capability, when a user wears the clothing carrier 300 having the electronic component 310 and the elastic conductive module 100 and performs related signal measurement, the elastic conductive module 100 can stretch along with the stretching action of the user without affecting the performance of the elastic conductive module, thereby reducing the foreign body sensation of disposing the elastic conductive module 100 on the surface of the clothing carrier 300. In addition, the elastic conductive module 200 can also be disposed on the surface of the clothing carrier 300 to achieve the same effect.

According to the embodiments of the present disclosure, the elastic conductive module has a good stretching ability through the configuration of the shape, the included angle, and the curvature radius of the elastic waterproof film and the elastic conductive pattern, so that the foreign body sensation caused by the configuration of the elastic conductive module on the surface of the carrier is reduced. In addition, the elastic conductive module has relatively more conductive channels through the alternate stacking of the plurality of layers of elastic waterproof films and the plurality of layers of elastic conductive patterns, so that the probability that the elastic conductive module cannot be used continuously due to failure is reduced.

Although the present disclosure has been described with reference to particular embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present disclosure, and therefore the scope of the present disclosure should be limited only by the terms of the appended claims.
