Large leaps in innovation promote the applicability of the technology and help reduce device cost significantly. Additionally, printed electronics are often perceived as a green technology with high potential of replacing established subtractive manufacturing methods and act as an enabler in many areas of society. However, their environmental impacts are still rarely investigated thoroughly. Device development for printed electronics typically starts with the definition of functionalities rather than exact knowledge about components and materials, making an integrated early-stage life cycle assessment (LCA) of the devices challenging due to the typically large amount of possible technical solutions for each use case. This contribution fundamentally supports the idea that getting involved with environmental considerations as early as possible in the development is pivotal in avoiding sustainability pitfalls from the start. Consequently, several LCA studies are summarised focusing on three different sustainability scopes: material, production and device, as well as use-phase and end-of-life. The work aims to provide an overview over the sustainability potentials and risks of the production processes of printed electronics from flexible substrates and conductive inks based on micro- and nano-sized particles. Different filler materials for the inks are considered, as their impact heavily influences the overall device impacts. In conclusion, recommendations for further work in the field are derived, summarising potentials of printed electronics, while equally considering remaining challenges. Thus, the conducted work contributes to a better understanding of environmental impacts in the development of printed electronics and helps applying the findings already at the very first development stages Note de contenu : - MATERIAL SUSTAINABILITY SCREENING : Substrates - Conductive particles - Conductive inks and adhesives - Functional components - Further components and materials - PRODUCTION AND DEVICE SUSTAINABILITY : Production processes - Combinatory approach for assessing device sustainability - SUSTAINABILITY OF USE-PHASE AND END-OF-LIFE Référence de l'article : 506 DOI : https://doi.org/10.1051/mattech/2022016 Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=37745 [article]
