The large deformation behaviors such as pressure, folding, distortion.
In the prior art, the Pan Kailin et al. of Guilin Electronic Science and Technology Univ. proposes " a kind of towards the soft of extending electronics
The scheme of property substrate ", the program improve the elongation percentage of extending electronics to a certain extent, but under large deformation, due to
The influence of poisson effect, the electronic component on the body of island will still bear biggish bending load, so that electronic component uses
The lost of life.
Summary of the invention
The purpose of the present invention is the structural matrix effective area occupation rate in existing extending electronics is not high and special
Under the body high selectivity of island, a kind of composite construction flexible substrate for flexible extending electronic device is provided.
Realize that the technical solution of the object of the invention is as follows:
A kind of composite construction flexible substrate for flexible extending electronic device, including substrate (1), groove (2), connection
Cylinder (3) and island body (4)；Equally array format is arranged on substrate (1) for connection cylinder (3)；Island body (4) is placed in connection
On cylinder (3)；It is separated between island body (4) and island body (4) by groove (2)；Electronic device is adhered on island body (4), connection
The conducting wire of electronic device is placed among groove (2).
Further, the connection cylinder (3) is polygon cylinder, including cylindrical body, square cylinder or diamond shape cylinder.
Further, the island body (4) is polygon cylinder, including cylindrical body, square cylinder or diamond shape cylinder.
In above two technical solution, the size in the section of connection cylinder (3) is significantly less than cutting for the island body (4)
The size in face.
Further, the substrate (1), connection cylinder (3) and island body (4) are integrated.
Further, the substrate (1), connection cylinder (3) and island body (4) they are hyperelastic flexible polymer, including

Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention, in which: 1, substrate；2, groove；3, cylinder is connected；4, island body.
Specific embodiment
As shown in Figure 1, a kind of composite construction flexible substrate for flexible extending electronic device, by substrate 1, groove 2,
It connects cylinder 3 and island body 4 forms.Composite construction flexible substrate is the basis with good ductility electronic device, and substrate 1 is to whole
A structure plays the role of carrying, bears the load such as be uniaxially stretched, be biaxial stretch-formed, reversing, be bent.Island body 4 is the collection of electronic device
At platform.Connection cylinder 3 primarily serves strain isolating effect, so that the large deformation being applied in substrate is not transferred to electronics device
Part.Groove 2 is to realize the extension effect be uniaxially stretched, be biaxial stretch-formed, reversing, be bent etc. in loadings.
Cylinder 3 is connected in polygons cylinders such as cylindrical body, square cylinder or diamond shape cylinders, in the preferred embodiment of the present invention
In, each connection cylinder 3 is square cylinder, and equidistant array format is arranged on substrate 1.Island body 4 is located at connection cylinder 3
On, each island body 4 is square bar shape.Island body 4 and connection cylinder 3 are all separated by groove 2.Substrate 1, connection 3 and of cylinder
Island body 4 is integral structure, is all made of hyperelastic flexible polymer, in the preferred embodiment of the present invention, using with resistance to
The dimethyl silicone polymer (PDMS) or polyimides (PI) of the performances such as corrosivity, high light transmittance, super-elasticity are made.Connect cylinder
3 lateral dimension will be significantly less than the lateral dimension of island body 4.
