Embodiment Construction

[0016] A flexible substrate for stretchable electronics such as figure 1 As shown, it consists of film substrate 1, island 2 and groove 3. The thin film substrate 1, the island 2 and the trench 3 are the electrical functional basis for realizing stretchable and flexible electronic devices. The film substrate 1 supports the entire device structure. The island 2 supports functional electronic components such as solar cells, and can realize stress isolation during stretching to protect functional electronic components. The groove 3, that is, the part that is not the island 2, is the basis for achieving high ductility. When stretching, bending and / or twisting, the size of the island 2 itself changes very little, mainly relying on the high stretchability of the substrate between the grooves 3. Achieving flexibility and extensibility of the entire structure.

[0017] Each island 2 is in the shape of a polygonal prism. In a preferred embodiment of the present invention, each islan...

Abstract

The invention discloses a stretchable electronic oriented flexible substrate, comprising a thin film substrate, islands and grooves. Each island is polygonal prism-shaped. All islands are arranged in a honeycomb array on at least one side surface of the thin film substrate. The islands are isolated by the grooves. Function devices are adhered above the islands. Connection leads are hidden in the grooves among the islands. The connection leads and the function devices are electrically connected. According to the flexible substrate, the stretchable performance such as axial stretching, bending and twisting can be realized, the defects traditional stretchable electronic function devices are low in surface occupation rate and too concentrated in stress are broken, the effective surface occupation rates of the function devices are improved, the working efficiency of stretchable electric products are improved, and the function devices can be protected well.

Description

technical field [0001] The invention relates to the technical field of extendable electronics, in particular to a flexible substrate for extendable electronics. Background technique [0002] Extensible electronics is a new type of electronic product, which overcomes the rigidity, brittleness, and fragility of traditional silicon-based electronic products, and cannot adapt to the application of more complex working planes. It is a representative product of advanced electronic manufacturing. Stretchable electronics based on structural substrates can be applied to highly sensitive robotic skins, eye-shaped digital cameras, flexible medical / surgical devices, smart health monitors, etc. However, the existing stretchable electronics based on structural substrates have problems such as low surface occupancy and excessive stress concentration on electronic devices. Contents of the invention [0003] The technical problem to be solved by the present invention is the problem of low...
