The unit cell MA is shown in FIG. 3 is slightly smaller than cell BA in the interactive device, but is not the smallest cell in the interactive device shown in Figure 3. Each unit cell MA is formed by the traces 22a of the first device array 20a and the traces 22b of the second device array 20b. Each device unit 21c of the third device array 20c is disposed within the unit cell MA formed by the traces 22a of the first device array 20a and the traces 22b of the second device array 20b.

The unit cell SA is shown in FIG. 3 The smallest cell in the interactive device shown. The minimum unit cell SA is formed by a combination of two or three of the traces 22a, 22b, and 22c.

In FIG. 3 , the device units 21 in the three device arrays 20a, 20b, and 20c are shown in different shapes for ease of distinction, but do not necessarily indicate the types of the device units 21 in the three device arrays 20a, 20b, and 20c. Different places. At the same time, for the sake of simplicity, in FIG. 3 , each trace 22 is represented by a straight line, but in practice, the trace 22 may have various shapes as described later.

In the above embodiment shown in FIG. 2 , the wiring 22b of the second device array 20b divides each unit cell BA into four approximately equal unit cells SA. In the embodiment shown in Figure 3, the traces 22b of the second device array 20b divide each unit cell BA into four approximately equal unit cells MA; each unit cell MA places a device unit 21c, and with The wiring 22c connected to the device unit 21c further divides the unit cell MA into four approximately equal unit cells SA.

In this embodiment, the substrate 10 may be a deformation material. The base 10 made of deformable material can deform to a certain extent or deform freely under the action of external force. In this way, when applied to products such as electronic skin, it can meet the needs of the product to transform between different states and have multiple forms. Require. Specifically, the material of the substrate 10 is styrene-ethylene-butylene-styrene block copolymer (SEBS, Styrene Ethylene Butylene Styrene), or polydimethylsiloxane (PDMS, Polydimethylsiloxane), or polyimide. (PI, Polyimide).

In one embodiment, the substrate 10 has a non-deformation area, and the non-deformation area includes the area where the device unit 21 is located. Arranging the device unit 21 in the non-deformation area on the substrate 10 can avoid interference and damage to the normal operation and function realization of the device unit 21 when the substrate 10 is deformed by external force, ensuring that the device unit 21 can work normally.

The non-deformable area provided on the substrate 10 can be achieved by performing a specific process on the surface of the substrate 10 made of deformable materials such as elastic materials. By performing surface treatment on the elastic material, the elastic modulus of the surface is reduced, so that the formed non-deformation area can maintain the surface morphology of the area where it is located when the substrate 10 is stretched, squeezed, deformed, twisted, etc., which has been achieved. Known existing technologies will not be described again.

Referring to Figure 4, combined with the above-mentioned Figures 2 and 3, for each device array 20, its multiple devices The component units 21 are arranged in multiple rows and multiple columns in a matrix arrangement. In the row direction, in the column direction, or in both directions of the row and column, the distance L2 between the non-deformation regions where adjacent device units are located may be 100 to 200 microns. In each device array 20, the non-deformation area where each device unit 21 is located can be a regular octagon; the length L1 of the side of the non-deformation area where each device unit 21 is located can be 50 to 150 microns, and the length is L1 The edges can be used to connect traces 22.

Referring to Figures 2, 3 and 4, each device unit 21 may be located at the center of the cell. When the base 10 is a deformable elastic base and the product form of the interactive device is an electronic skin, this arrangement facilitates designing the elastic deformation amplitude of each area on the base 10 to meet the requirements under different deformation states and prevent the base 10 from being damage. However, in other embodiments, each device unit 21 may not be located at the center of the unit cell.

In one embodiment, in each device array 20 , the trace 22 between two adjacent device units 21 has at least a first interval, and within the first interval, the shape of the trace 22 is non-linear.

When the substrate 10 is deformed under the action of external force, the partially folded traces can be pulled and unfolded, so that the effective connection between the two device units 21 can be maintained in the deformed state. Specifically, the traces 22 can be made of a material with certain ductility. With such arrangement, the traces 22 can better and more reliably achieve effective connections between the device units 21 through their own extension when being pulled by an external force. .

In other embodiments, the shape of the wiring in the first section (for example, the section between node M and node N) is a curve, or a polyline, or a folded wiring formed by extending back and forth in a specific direction. Generally, as long as the traces 22 in the first section are not straight-line structures, when subjected to external force, the traces 22 can be pulled and transformed into straight lines to provide a certain stretchable space, and the deformation amplitude of the substrate 10 does not exceed When the range is within the extended range, the effective connection between the two device units 21 is ensured.

As shown in Figure 2, there are cells BA1 and BA2 in Figure 2. Trace 22a1 is for two cells BA1 and BA2 The common side is the line that separates the two cells BA1 and BA2. Device units 21b1 and 21b2 are respectively provided in the cells BA1 and BA2, and the trace 22b1 is a trace connecting the two device units 21b1 and 21b2. As can be seen in Figure 2, there is only one intersection between trace 22b1 and trace 22a1. This arrangement helps to simplify the structure between the traces 22 and more conveniently realize their intersection and insulation. In this embodiment, in order to achieve this, the folded wiring structure as shown in Figure 2 is not provided at the intersection of the two traces 22. At the intersection of the two traces 22, the shape of each trace 22 is It may be linear or arcuate, and as shown in FIG. 2 , it is preferably linear.

At the intersection of two traces 22 , the shape of each trace 22 is not set to a folded trace structure. The deformation amount of the traces 22 and the substrate 10 can also be limited in the intersection area of the traces 22 to avoid the deformation of the traces 22 . The deformation of the wires 22 and the substrate 10 has an adverse effect on the area where the wires 22 are connected and damages the structure at the junction of the wires 22 .

Referring to Figure 1, the interactive device includes a protective layer 23. The protective layer 23 is formed above the device array 20; the material of the protective layer 23 is one or a combination of silicon nitride, silicon oxide, polyimide and acrylic. . The protective layer 23 can isolate the device array 20 from other structures and the outside world, and can also provide protection for the device array 20 .

In one embodiment, multiple device arrays 20 are located on different layers, and an isolation layer is provided between each device array 20 and other device arrays 20 . The isolation layer may be a structure of a layer of substrate 10, or may be a structure of a layer of protective layer 23, as shown in Figures 5 and 6 respectively.

In another embodiment, at least two device arrays 20 of the interactive device are located on the same layer (in the case where the number of device arrays 20 is more than three, all device arrays 20 may be located on the same layer). At the intersection of the traces 22 of the device array 20 , one trace 22 passes under the other trace 22 , forming a structure similar to an underground passage in an urban transportation system, as shown in FIG. 7 . Alternatively, one of the traces 22 may pass through the upper side of the other trace 22 to form a structure similar to an overpass in the urban transportation system, as shown in FIG. 8 . On this basis, an isolation part is further provided at the intersection of the two traces 22 to isolate the two traces 22 to ensure insulation between the two traces 22 . The isolation part may be a layer of base 10 structure or a layer of protective layer 23 structure, as shown in Figures 7 and 8 respectively.

In one embodiment, the interactive device may include a first substrate 11 and a second substrate 12.

In this embodiment, a plurality of device arrays 20 are respectively formed on the first substrate 11 and the second substrate 12, which themselves are equivalent to a complete interactive device as mentioned above. In this embodiment, the two are equivalent to each other. The interactive device connected together as a whole can have more device arrays 20 so as to obtain better interactive effects. Specifically, the first substrate 11 and the second substrate 12 may be connected in an adhesive manner through an adhesive layer 13 .
