| 1 | A fully inkjet-printed disposable gas sensor matrix with molecularly imprinted gas-selective materials显示文摘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. | Lingpu Ge Xiao Ye Zeping Yu Bin Chen Chuanjun Liu Hao Guo Shiyi Zhang Fumihiro Sassa Kenshi Hayashi | 2022 | npj Flexible Electronics2022，6，1： | 0 |
