Feature Topics in Sustainable Electronics
Four key complementary topics, from materials and devices to systems and packaging, are covered
- The role of packaging for sustainable electronics by Nils Nissen, Head of Department Environmental and Reliability Engineering form Fraunhofer IZM
- The major sources of environmental impacts from electronics are outlined with a zoom into the specific role of electronics packaging – meaning advanced packaging of integrated circuits as well as the substrate and interconnection options. From a systems perspective and a circular economy view, packaging plays a larger sustainability role than just the comparatively small impacts associated directly with the packaging processes. – [Starts at 0:50]
- Compostable materials for sustainable sensing: Rapid laser fabrication of 3D porous graphene from chitosan biopolymers by Aidan Quinn, Head of Nanotechnology group at Tyndall
- There is increasing interest in laser methods for direct-write formation of graphitic and graphene-like carbon structures from sustainable materials. Chitosan is the second most abundant natural polysaccharide after cellulose. Here we report on site-selective laser-induced formation of porous 3D graphene on flexible and water-soluble chitosan films using low-cost lasers. Raman spectroscopy demonstrates formation of high-quality graphene (sharp 2D peak). We have also demonstrated proof-of-principle impedance-based sensing for humidity and also acetone vapour. – [18:40]
- Some opportunities for greener electronics by Thomas Ernst, Scientific Director at CEA-Leti
- The complete ecosystem of electronic device manufacturers, from microelectronics, software and hardware designers to developers, producers, and integrators, is facing an immense new environmental challenge: to reduce the global energy consumption of digital technologies. We purpose scientific and technical directions to reach global data and power sobriety while preserving computational efficiency. A growth factor of 100 to 1000 in energy efficiency is achievable in the next 10 years if we take full advantage of all the potential improvements, working simultaneously at all five levels of the technological ecosystem (process steps, circuits, architecture, software and algorithms). – [35:45]
- Environmentally Friendly Graphene Inks for Flexible Electronics by Andrea Capasso – INL
- The development of graphene-based nanomaterials for flexible electronics is of high interest to the industry. Graphene-based liquid dispersions are suitable for depositing films with high electrical conductivity, transparency, and flexibility at a low cost that are compatible with a wide range of substrates. To date, graphene dispersions present some limitations, particularly the use of efficient yet hazardous solvents with limited substrate compatibility, high boiling point, and toxicity, which are all undesirable features for industrial production. We propose a novel approach to produce graphene-based dispersions with high yield and control on the material properties using a new green carbon solvent – Cyrene, which could replace toxic and hazardous solvents such as NMP and DMP in the exfoliation process. We obtain stable graphene dispersions with concentrations above 4 mg/mL (with lateral size of the graphene flakes between 30 and 500 nm). The dispersions can then be deposited by several techniques (e.g., spray coating, inkjet, screen-printing, etc.) on various substrates to fabricate films with desired levels of transparency and conductivity. As a proof of concept, a 20×20 channel multi-touch screen prototype was successfully fabricated on PET by spray coating graphene ink through polymeric masks cut in a microplotter. – [52:00]
Discover ASCENT+ JRAs (Joint Research Activities)
Another important part of the ASCENT+ programme is the Joint Research Activities: Within JRAs the ASCENT+ Access Providers work with leading academics to advance the state-of-the-art in the ASCENT+ offer portfolio. There are three JRAs that align to the Technology Drivers (Quantum Advantage, Low-Power High-Performance and Functional Diversity) and one overarching JRA that enhances the infrastructure offering as a whole.
Within the ASCENT+ Joint Research Activities, Johannes Kepler Universität Linz (JKU) provides expertise and tools for the fabrication of sources of quantum light for scientific experiments as well as to applications in emerging quantum communication and photonic quantum computing. Particularly relevant within ASCENT+ is die-bonding and various bonding techniques enabling the integration of quantum light emitters (e.g. epitaxial quantum dots) onto piezoelectric actuators. The resulting hybrid platforms allow fine-tuning of the electronic and optical properties of the quantum emitters, is compatible with cryogenic operation, and allows addressing the demanding requirements of emerging quantum technologies.
Flashlight: ASCENT+ Offering

Upcoming joint event IRDS – ASCENT+
ASCENT+ has dedicated a Task to the International Cooperation with Policymakers / Strategic Roadmapping as it highly important to ensure a positive alignment between the future offer and current strategic research and innovation agendas. For this purpose, a joint event will be soon organised with IRDS “International Roadmap for Devices and Systems” and in particular with its “Cryogenic Electronics and Quantum Information Processing” International Focus Team.
A webinar on Quantum Computing will be jointly organised with IRDS: stay tuned!
