Background technique [0002] Various fabrication techniques, such as MEMS, reactive ion etching, chemical vapor deposition, nanoimprinting, soft lithography, and other process methods have been widely used in the fabrication of flexible sensors on 2D planar substrates. Due to the particularity of manufacturing technology, these processes cannot be directly used for conformal fabrication of flexible sensing devices on 3D curved surfaces. However, with the rapid development of flexible electronics, there is an increasing demand for flexible and deformable sensors. In recent years, researchers have used various flexible and stretchable nanomaterials and their composite materials to explore the manufacturing methods of flexible sensor devices, so that they have large ten...

Problems solved by technology

This process method is cumbersome and time-consuming, and some 3D patterns cannot be split into 2D patterns, and there are technical limitations in the adaptability of 3D curved surfaces

At the same time, the process of splicing 2D planes into 3D curved surfaces is likely to cause a decrease in sensor accuracy

It can be seen that the existing manufacturing process needs to be improved in terms of processing efficiency, processing accuracy and 3D surface adaptability.
