Description

technical field [0001] The invention relates to the technical field of flexible electronic circuit pattern manufacturing, in particular to a method for electrohydrodynamic jet printing of any three-dimensional flexible electronic circuit pattern. Background technique [0002] Flexible electronics is an emerging electronic technology that makes organic / inorganic material electronic devices on flexible / ductile substrates, including flexible sensors, flexible electronic displays, flexible light-emitting diodes, flexible solar cells, flexible radio frequency devices and other flexible electronic devices. It has broad application prospects in medical, national defense and other fields. At present, most flexible electronic devices are two-dimensional planar structure devices, which have poor deformability and are difficult to conform to the surface shape of the three-dimensional structure of three-dimensional objects. In order to realize the transformation of flexible electronic ...

AI Technical Summary

Problems solved by technology

Although the manufacturing method of flexible electronics with three-dimensional structure is relatively simple, the shape of the manufactured flexible electronic three-dimensional structure is relatively simple, and the deformation of the three-dimensional structure produced by flexible electronics is limited by the deformation of the flexible / ductile substrate. The demand for surface shape produces its corresponding deformation, which leads to the deformation of the three-dimensional flexible electronic device that cannot be seamlessly attached to the surface of the three-dimensional object, and the flexible electronic device is easy to fall off the surface of the three-dimensional object during use
