The use of printed electronics is rising fast as we move toward the internet of things (IoT). Today, most printed electronics are printed on nonbiodegradable polymers resulting in an exponential increase in E-waste formation. The current printing technologies are liquid/ink-based which are not compatible with biodegradable substrates such as papers. Here, we introduce a novel dry printing method to print conductive silver patterns on biodegradable papers. The effect of different printing parameters on the paper burning threshold is investigated, and the electrical characteristics of the lines are characterized for different line thicknesses and widths. Furthermore, the mechanical properties of the lines are studied by bending, twisting, and adhesion tests. This dry printing technology can pave the way toward eco-friendly and biodegradable papertronics.
