Abstract

Printed circuit boards (PCB) are essential components of nearly all forms of commercial electronics, where they provide mechanical supports and electrical interconnections for mounted components. Modern PCBs offer multilayer configurations, capable of high frequency signal conduction with minimal transmission loss, and robust, reliable performance in various environmental conditions over extended periods of time. One potential route to reduce electronic waste streams is to build the electronics using materials that can naturally degrade into biologically and environmentally benign end products on timescales that exceed desired device lifetimes. Screen printing methods similar to those used in manufacturing of conventional PCBs are useful for fabricating transient analogs. As examples, screen-printed transient conductive pastes on Na-CMC substrates can yield circuits for wireless power harvesting and near field communication (NFC) devices.
