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]

Sustainability screening in the context of advanced material development for printed electronics / Florian Gehring in MATERIAUX & TECHNIQUES, Vol. 109, N° 5-6 (2021)  

[article]  inMATERIAUX & TECHNIQUES > Vol. 109, N° 5-6 (2021) . - 11 p. Titre : Sustainability screening in the context of advanced material development for printed electronics Type de document : texte imprimé Auteurs : Florian Gehring, Auteur ; Tobias Manuel Prenzel, Auteur ; Roberta Graf, Auteur ; Stefan Albrecht, Auteur Année de publication : 2022 Article en page(s) : 11 p. Note générale : Bibliogr. Langues : Anglais (eng) Catégories : Durée de vie (Ingénierie) Eco-conception Electronique imprimée Index. décimale : 658.408 Ecobilan-Protection de l'environnement Résumé : Flexible, ultra-light and wafer-thin – the future of electronics is printed! The cornerstones for this development are conductive inks and adhesives that connect components and sensors with each other, integrating them into a printed environment. A decisive role hereby is played by advanced materials, such as functional inks, and their interaction in final devices for application in various use-cases. For this purpose, various particle structures in the nanometre range are created that enable the required conductivity, while keeping material input of the conductive substance as low as possible. Due to the excellent properties, the versatile functionalities, the possible high production volumes and the associated reduced production costs a wide range of applications is facilitated through printed electronics and mass markets become accessible. Therefore, associated environmental impacts as well as the security of the supply chain are expected to gain further relevance in the future. Yet, as most of the processes are in a development stage, prospective assessments before the start of production are essential, if development of printed electronics shall be aligned with sustainability goals. In order to address environmental consequences of future implementations of advanced materials for printed electronics at an early stage, this contribution is considering and evaluating the sustainable effects in a comprehensive assessment even before the physical start of product and material development. To this end, a procedure was developed, in which underlying methodology enables development engineers to identify hotspots at an early stage and to address and mitigate them early on. This way, challenges of tomorrow’s circular economy are already being addressed today and critical sustainability pitfalls can be avoided.
