| Abstract:This paper reviews the preparation and application progress of paper-based intelligent flexible sensors, with emphasis on typical fabrication processes, including coating, impregnation, printing, and laser processing. The roles of these methods in conductive network construction, interfacial bonding, patterning, and sensing performance regulation are analyzed. The applications of paper-based intelligent flexible sensors in human health monitoring, environmental information sensing, food safety detection, and human-machine interaction and intelligent recognition are summarized. Finally, the future development of paper-based flexible sensors toward high performance, green manufacturing, and practical application is prospected. |
