A method was used to fabricate a fully inkjet-printed gas sensor matrix on photographic paper. An electrode matrix comprising 36 interdigital electrodes in a high-density layout that is easy to integrate has been fabricated using a combination of insulating ink and commercial silver ink. Molecular-imprinted polymer (MIP) inks were then made using a simple solution mixing method, and these inks were printed together with carbon black ink on the electrode matrix to complete production of the sensor. Finally, experimental dynamic sensing of volatile organic compounds verifies that for detection of gases corresponding to the MIP template molecules, the MIP layer offers improvements in both sensitivity and selectivity when compared with non-imprinted polymer layers. The matrix can produce a response of more than 20% to 3 ppm propenoic acid gas through adjustment of the printing times for the carbon black layer and the MIP layer.

使用一种方法在相纸上制造完全喷墨打印的气体传感器矩阵。使用绝缘墨水和商业银墨水的组合制造了一种电极矩阵，该电极矩阵包含 36 个高密度布局的叉指电极，易于集成。然后使用简单的溶液混合方法制成分子印迹聚合物（MIP）墨水，并将这些墨水与炭黑墨水一起印刷在电极矩阵上，以完成传感器的生产。最后，挥发性有机化合物的实验动态传感证实，对于检测对应于 MIP 模板分子的气体，与非压印聚合物层相比，MIP 层在灵敏度和选择性方面都有所提高。
