Optimization of microscopic analysis of paper printed electronics

Printed electronics is a field of electronics that involves printing of electronic devices and components on a variety of substrates, including paper, plastic, and textiles. This technology uses printing techniques including inkjet printing, screen printing and gravure printing to create circuits, sensors, displays and other electronic devices. Advantages of printed electronics include low-cost production, design flexibility and compatibility with a range of materials. From the perspective of sustainable electronics, paper-based substrates are one of the most promising solutions. When silver ink is printed on paper, the solvent evaporates, leaving a layer of silver nanoparticles that are fused together to form a conductive layer. This layer can be used for a variety of applications, such as creating conductive traces for electronic circuits or antennas for RFID tags. However, there are also some challenges in characterizing of printed ink on paper leading to miss-information about its quality. Since paper contains fibers, it creates a highly roughened surface, and the traditional characterization method used for plastic-based substrates must be adopted to the needs of paper.
