From Liquid Metal droplets to stretchable, self-healing, and sinter-free printed hybrid electronics
University of Coimbra
Mahmoud Tavakoli
When it comes to stretchable electronics, e-textile, smart gloves, and wearable patches, Liquid Metals (LMs) are becoming the number one choice for most researchers. But research on LMs are also entering fields of energy storage, thermal interfaces, displays, energy harvesting, and even carbon capture. This is due to the excellent combination of electrical and thermal conductivity and fluidic deformability, that makes liquid metals the first choice for many applications. However, unlike the electrically conductive inks and pastes, LMs are not easy to deposit and pattern, they are smearing, and interfacing them with microchips is not straight forward. The good news is that these problems are being addresses rapidly, and there are already some steps toward commercialization of LM based electronics.
In this master class I will summarize the research on liquid metals during the last 15 years, and will demonstrate various aspects of liquid metals. The talk will be divided into 3 sections: Materials (Liquid Metals, LM composites, LM micro and Nano droplets), Fabrication Techniques (Deposition, Patterning and Microchip Interfacing) and Applications. I will talk about the results of electromechanical testing, and durability of circuits when subjects to over 100, 000 strain cycles. I will as well talk about the applications in the space of smart textiles, wearable patches, additive manufacturing, and mechanical sensing, and how some of the top manufacturers (e.g. in automotive sector) are already adopting solutions. If time permits, I will briefly talk about how LMs are entering the energy storage field, both as current collectors, and as active electrodes.

The Role of Bio-based Materials and Additive Manufacturing in Achieving Sustainability Goals for Electronics
RISE
Jesper Edberg
Electronic waste (e-waste) poses a pressing global challenge with the World Health Organization (WHO) reporting a staggering annual generation that exceeds 50 million tonnes. Less than 20% of this waste is recycled, highlighting severe environmental and health risks associated with the disposal of hazardous materials such as lead, mercury, and flame retardants. This challenge is further compounded by the overreliance of the global economy on rare earth elements and critical raw materials. Addressing this crisis requires a concerted effort to align with the United Nations Sustainable Development Goals (SDGs), particularly Goal 12 (Responsible Consumption and Production), which emphasizes reducing waste generation and promoting sustainable practices. Achieving this goal requires a paradigm shift in the electronics industry. Our course delves into the urgent need for sustainable materials and manufacturing methods within electronics. We explore alternatives to synthetic, often non-sustainable materials like PFAS (per- and polyfluoroalkyl substances) which persist in the environment and harm ecosystems. - Enter biobased materials—nature-inspired alternatives: Derived from renewable sources like trees, plants and algae, these materials offer a greener path. We’ll explore their properties, applications, and potential to revolutionize electronic design. - Additive Manufacturing and Printed Electronics: Create intricate electronic components layer by layer, minimizing waste and energy consumption for thin flexible solar panels, printed circuit boards, sensors, displays and more. We explore how these innovative techniques can reduce environmental impact. Join us on this journey toward sustainable electronics. Let’s design a future where innovation meets responsibility.
12:00 PM
Chip Interconnections for Flexible Printed Electronics.
Beckermus Technologies
Aviv Ronen
In this masterclass we will learn the packaging hierarchy and learn how the chip interfaces and structure can help us in building a reliable electronic system. We will see how wire bonding, although famous, is not suitable for the flexible electronic eco-systems and than we see how flip chip bonding is better but still has it disadvantages.
We will see how solders and conductive adhesive has their pros and cons and how they both suffer from thermal mechanic stresses when bonding in elevated temperatures. Therefore, we will see why there is a motivation for lowering this temperature not only because the materials cannot withstand these elevated temperatures.

Opportunities for improving sustainability and circularity for electronics
VTT
Liisa Hakola
The EU is proposing a Regulation on Ecodesign for Sustainable Products (ESPR) that sets requirements for all products in the EU market to become more sustainable, circular, energy-efficient, and environmentally compatible. The EU has specified electronics and ICT sector as one of the priority sectors that the ESPR will regulate. The current electronics industry causes significant direct and indirect environmental impacts, such as the formation of electric and electronic waste (e-waste), great demand for critical raw materials (CRMs), and high energy consumption during manufacturing. Therefore, actions are required to meet the requirements from the upcoming regulation. The electronics industry has several opportunities to increase its sustainability and circularity. These include among others (1) shifting from fossil-based, critical and rare materials to renewable, bio-based and abundant materials; (2) utilization of additive manufacturing processes that offer material and energy efficiency; and (3) utilization of circular economy business models for extending product use life with e.g. reuse, repair and recycle concepts. Since typically 80% of the environmental impacts are determined during the design phase, the product design is a critical stage when targeting more sustainable products that must balance between cost, performance, and sustainability aspects. This masterclass specifies sustainability (environmental, social, economic) and circularity for electronics industry, covers areas with opportunity for more sustainable approach, highlights means to improve environmental sustainability (green electronics), and discusses the relevant regulatory aspects.

From Sustainable to Circular: these are the challenges for Printed Electronics
Holst Centre
Stephan Harkema
The environmental impact of electronics has to be reduced. Therefore, we need to make the transition from petrochemical materials to bio-based, recycled or bio-degradable alternatives. This important first step is within reach. The second step is to reduce the complexity of products and the amount of materials used. The result: lower impact from materials and manufacturing, but also reduced fuel emissions during a product’s lifetime. Many other circular strategies must be implemented if we want to further reduce a product’s impact. One such strategy would be to prevent replacement before a product’s end-of-life by extending its lifespan through repair or refurbishment. But what if we have exhausted all these circular strategies? How can we recover the valuable materials and components if these materials are fused together? This presentation addresses some of the challenges involved with end-of-life treatment of hybrid & printed electronics.
