Based on the application challenges of low cost, configurable, and high environmental compatibility of the next-generation Internet of Things (IoT) wireless sensor network (WSN) devices/nodes, this project adopts the addition method of paper-based metal conductive lines and RF antennas as the main process route, and develops low-cost preparation of WSN devices/nodes that are flexible and easy to be handle. In this project, we proposed a ink-jet printing preparation process of paper-based metal interconnect pattern based on printability regulation. Printable solution-type catalytic inks were firstly printed on the physicochemical modified paper to form patterns having strong chemical switch effect, and then metal film circuits of excellent performance were obtained by means of binding chemical deposition. In the project, we will study the regulation mechanism of paper surface state printability, and optimize the formulation system and high-precision printing transfer of the solution-type catalytic ink. Moreover, we will explore the constrained chemical deposition growth and reliability of paper-based metal film. Finally, integrated ink-jet printing technology of paper-based metal conductive pattern of excellent performances (high conductivity, high precision, high resolution, high mechanical reliability, good adhesion, and easy-print ink without high temperature sintering) is successfully obtained. Hence, the research plays a significant role in not only promoting the application of paper-based WSN devices/nodes, but also laying foundation of the further development of our country’s IoT technique and industry.
