Shape-adaptive magnetic control self-sensing flexible pipeline and preparation method thereof

Abstract

The invention discloses a shape-adaptive magnetic control self-sensing flexible pipeline and a preparation method thereof. The shape-adaptive magnetic control self-sensing flexible pipeline comprisesa hollow cylindrical flow field pipeline, a plurality of turns of coils, a plurality of anisotropic magnetic sensitive elastomers and a piezoelectric film sensor, the plurality of anisotropic magneticsensitive elastomers are arranged on the cross section of the flow field pipeline in a central symmetry manner, the plurality of turns of coils are arranged on the outer surface of the correspondingposition of the flow field pipeline, and the piezoelectric film sensor attached to the anisotropic magnetic sensitive elastomers senses the deformation of the magnetic sensitive elastomers to achieveself-sensing of the flexible pipeline. The pipeline is simple in structure, low in material cost and diverse in function. The sizes of the anisotropic magnetic sensitive elastomers and the piezoelectric film sensor are easy to control, so that the flow field pipeline has excellent shape adaptability. The off-surface deformation of the anisotropic magnetic sensitive elastomers is changed by adjusting a magnetic field generated in the pipeline after the plurality of turns of coils are electrified, so that the cross sectional area of the pipeline is changed. The deformation degree of the anisotropic magnetic sensitive elastomers is obtained through the piezoelectric film sensor, and self-sensing is achieved.

Description

technical field [0001] The invention relates to a flexible pipeline, in particular to a shape-adaptive magnetically controlled self-sensing flexible pipeline and a preparation method thereof. Background technique [0002] Compared with rigid pipes, flexible pipes have better flexibility and less damage to the transported materials. They are widely used in food processing, natural gas transportation, sewage treatment and other industries. In addition, micropipes with a certain elasticity of tens to hundreds of microns are an important part of microfluidic chips, which are used to process or manipulate tiny fluids, and have great development potential in biomedical research. However, whether it is a flexible pipe or a micropipe, most of them have a fixed cross-sectional area, or only open and close two working conditions, it is difficult to achieve continuous control of the material flow rate. Moreover, when transporting toxic and harmful materials, it is not safe to manually...

Problems solved by technology

However, whether it is a flexible pipe or a micropipe, most of them have a fixed cross-sectional area, or only open and close two working conditions, it is difficult to achieve continuous control of the material flow rate

Moreover, when transporting toxic and harmful materials, manual switching of pipeline valves is not safe

The traditional magnetic control pipeline valve can be remotely controlled by connecting the power line of the electromagnetic coil, but the structure is relatively complicated
