Abstract

Fused Deposition Modeling (FDM) 3D printing technique can be considered as an efficient technology for the production of functional three-dimensional devices in micro/nanoelectronics, such as gas sensors. The production of gas sensors via FDM 3D printing is promising in the Materials Science domain, due to the simplicity of the manufacturing method, with a diversity of geometries and formulation possibilities of semiconductors embedded in polymeric matrices. In addition, other aspects such as improved sensor sensitivity and stability, justify the exploration of the technique for the production of new gas sensors design. In this context, this communication presents a brief study about gas sensing devices developed by FDM 3D printing technology, and the perspectives of this research topic in the literature.
