Research progress in manufacturing flexible sensors based on 3D printing technology

In recent years, flexible sensors have been widely applied. Compared with traditional processing methods such as coating and deposition, 3D printing technology can be used to produce sensors with complex three-dimensional functional structure. Combining 3D printing with flexible sensing technology can promote the development of biomedical and artificial intelligence in the future.This paper introduces the latest developments in the manufacture of flexible sensors based on 3D printing technology at home and abroad, including a variety of substrate materials such as polyimide, printing sensing materials such as nano metal. According to the manufacturing principles of fused deposition, viscoelastic ink deposition, powder sintering, reduction photopolymerization and material ejection, the material selection, molding characteristics and the manufacturing methods are summarized and analyzed. Although 3D printing manufacturing flexible sensor devices has a lack of industry standards and a variety of printing materials and so on, 3D printing will become an excellent manufacturing method in the field of flexible sensing through continuous innovation and development.
