Abstract

The invention discloses a full-flexible polymer intelligent skin. Functional modules are all integrated on the same flexible substrate, the full-flexible polymer intelligent skin comprises a piezoresistive strain array based on a conductive polymer 1 and a capacitive sensing array utilizing a conductive polymer 2, wherein the piezoresistive strain array and the capacitive sense array are integrated, and the full-flexible polymer intelligent skin is used for monitoring strain and pressure distribution of a train head. In addition, the invention provides a preparation method of the full-flexiblepolymer intelligent skin. According to the key points of the preparation method, the strain sensing module based on the conductive polymer 1 and the capacitive pressure module based on the conductivepolymer 2 are prepared and integrated on the stretchable substrate, the sensing array is prepared through a solubilization method, full-solubilization industrial large-batch scale production is supported, the designed and prepared full-flexible intelligent skin is bonded on a complex structure on the surface of the train head and used for recording strain and pressure information in the train head during train operation, health monitoring of the train head structure is achieved, and stable high-speed operation of the train is ensured.

Description

technical field [0001] The invention relates to the field of flexible electronics and intelligent skin, in particular to a fully flexible polymer intelligent skin device and a preparation method. Background technique [0002] The health status of the locomotive structure of a high-speed train is closely related to the safe running of the train. How to effectively monitor the structural health information of the locomotive has always been a research hotspot. Smart skins are widely bonded to the surface of objects with complex shapes, and will have great prospects in the health monitoring of high-speed train head structures. The rapid development of my country's high-speed rail technology has brought great pressure to the safety of high-speed rail trains. Applying intelligent skin technology to high-speed trains will improve the safety of train operations. [0003] Smart skin technology has been applied in aircraft, bridges and other fields, but it is mainly based on traditio...
