Description of the drawings
Fig. 1 is a kind of dimensional structure diagram of the flexible substrates towards extending electronics.
Label in figure：1st, film substrate；2nd, island；3rd, groove.
Specific embodiment
A kind of flexible substrates towards extending electronics, as shown in figure 1, being made up of film substrate 1, island 2 and groove 3.
Film substrate 1, island 2 and groove 3 are the electrical functions bases for realizing extending flexible electronic device.Film substrate 1 pair is whole
Device architecture is realized supporting.The support to function electronic devices and components such as solaode is realized on island 2, and can be in stretching
During realize stress isolation so as to function electronic devices and components realize protect.Groove 3 is 2 part of non-island, is realized high
The basis of ductility, when stretching, bending and/or torsion, the change in size very little of island 2 itself relies primarily on the base between groove 3
The high scalability at bottom is realizing the flexible and ductility of total.
Each island 2 is in polygon-prism shape, and in this utility model preferred embodiment, each island 2 is in six sides
Shape prism-shaped, which can improve device surface occupation rate, and overcome stress to cross the problem of concentration.All island 2 are in film substrate 1
An at least side surface on arrange in honey-comb shape array, i.e., all island 2 can with regular array film substrate 1 a side surface
On, it is also possible to regular array is in the both side surface of film substrate 1.Separated by crisscross groove 3 between island 2.Island 2
It is integrated with film substrate 1, and is made up of identical material.The material be elastomeric flexible polymer, such as PDMS
Or the elastic material such as TPU, which is both total ductility, the key of high surface coverage, is to realize stretching, turn round again
Turn, bending etc. extending mechanical behavior basis.
The height on island 2 is 0.75～2 with the ratio of the thickness of film substrate 1, to realize preferably to 2 top function of island
The protective effect of device.In this utility model, the very thin thickness of film substrate 1, less than 1 centimetre.Use 2, island, 3 part of groove
In placement connecting wire, therefore 3 width of groove can not be too small, is needed more than 100 microns under normal circumstances.The depth of groove 3 with
The ratio of width is 1.5～5.In the action processes such as stretching, bending and torsion are realized, as groove 3 has high depth-to-width ratio, make
Obtain and there is at island 2 good stress isolation effect, it is very little to the stress of functional device, it is prevented from functional device
Come off and realize to its stress isolation protection, so as to, while ductility, high surface coverage is realized, realize high reliability.
In order to form extending flexible electronic circuit, in addition it is also necessary to arrange connecting line on the basis of above-mentioned flexible substrates
And functional device.Connecting line and functional device are used for the electrical functions for realizing extending flexible electronic device.Functional device is whole
The functional realiey part of individual equipment, which can be selected according to the needs of different application occasion.Connecting line is to realize that electricity connects
The part for connecing.
Functional device sticks to the top on island 2, for realizing higher work efficiency in limited area.Additionally,
Adhesion layer is provided between functional device and island 2, so as to assurance function device can be realized preferably being connected with the top on island 2, and
And play certain stress buffer effect.
Connecting wire is arranged on the lower section of each functional device, and inside the groove 3 between each island 2, which had both saved sky
Between, big ductility is provided again, while can be protected by top electronic device and structural substrate.Connecting wire by copper or
Connecting wire made by silver, with high conductivity, connecting wire shape is designed to hexagonal array structure, so as to draw
Big ductility is realized in the case of stretching, rectangular array structure connecting wire is to realize the ductility and electrical functions of whole mechanism
Basis.Connecting wire is electrically connected with functional device.The junction of connecting wire and functional device is located at the side of functional device
Edge or lower section.
If functional device is solaode, adhere to above island 2, need to receive as much as possible in limited area
Illumination, so as to convert light energy into power storage.Each solaode is adhered to above a corresponding island 2, and each is too
Positive energy battery is directly connected by connecting wire with four solaodes of surrounding, so as to realize each electronics unit in total
Device solaode is electrically connected.Additionally, in order to integrally protect to extending electronic device, can as needed,
Optionally encapsulated layer is added in the top of whole extending electronic device.
