Problems solved by technology

[0003] The characteristics of the current flexible substrate materials are stretchable, bendable, uniform force distribution and no directionality. This characteristic leads to the consistent force distribution of electronic devices and wires, which can straighten the flexible substrate and flexible wires. No fracture will occur under the condition of a large range of deformation, but the flexible circuit in the flexible electronic device will be damaged in a small range of deformation

This situation leads to the fact that under the action of external force, the flexible circuit is saturated and the stretching performance of the wire has not yet been exerted.

Secondly, under the impact of external force, the flexible circuit is thicker than the wire. First, it can withstand more impact force, but the relative energy absorption capacity of the flexible circuit is relatively poor, and it is easy to break and fail under the impact of external force.

In the prior art, in order to ensure that the flexible circuit is not damaged under impact, it is necessary to make a thicker flexible protective layer, which increases the thickness of the flexible electronic device on the one hand, and on the other hand affects the bending performance of the flexible electronic device. make an impact

Therefore, the property that flexible circuits are prone to breakage under impact has become a major factor limiting the development of flexible electronics.
