Is Printed Electronics a Sustainable Technology? A Framework to Efficiently Implement an Early-Stage Life-Cycle-Analysis — •Laura Teuerle, Tommy Meier, Klara Hänisch, Finn Jaekel, Yeohoon Yoon, Andreas Wendel, and Hans Kleemann — Dresden Integrated Center for Applied Physics and Photonic Materials, TU Dresden, Germany

The rise of microelectronic system has been the major driving focus of the global economy for the last couple of decades. As we are now transitioning to the era of the internet-of-things, with an increasing number of small autonomous electronic circuits, e.g, for sensing, we need to urgently consider the environmental impact of this development due to the unsustainable use of natural resources. Thus, to ensure the environmental sustainability of the development, future electronics must prioritize both performance and environmental impact, explaining the interest in flexible and printed electronics. However, the sustainability claims often connected to the field of flexible and printed electronics must be substantiated using analytic methods, providing the motivation for quantitative Life-Cycle Assessment (LCA). Here we demonstrate our approach to implement an LCA for an early-state research topic such as Organic Electrochemical Transistors (OECTs). Using hands-on examples, we will show how to set up an inventory database (the core of the LCA) using a process-of-record (PoR). By making LCA a standard tool in printed electronics, the community can move beyond sustainability claims to measurable environmental impact, driving truly responsible innovation in electronics.
