Sustainable Electronics: Understanding and Analysing Sustainability Aspects of Printed Electronics

Stephan Harkema

Holst TNO

Transitioning from conventional Printed Circuit Boards (PCBs) to future electronic products based on Hybrid and Printed Electronics (HPE) provides immediate opportunities to achieve ecological benefits: use of recyclable thermoplastic polymers, reduced device thickness, lower weight and additive manufacturing instead of deductive manufacturing. You will learn about the environmental impact of Hybrid and Printed Electronics and what is needed to adapt this technology to circular economy. In both types of electronics, PCBs and HPE, the circuitry and surface mounted devices (SMDs) contain potentially critical, high impact metals, some of which, if not all, are embedded in plastics to protect them from external influences. Designs-for-recycling are relatively unexplored, leaving many critical metals trapped in their plastic casing. You will learn about example designs-for-recycling for HPE and their (potential) impact to the overall environmental footprint.

HMIs with Integrated Smart Functions

Sebastian Gepp

Over time such membrane keyboards very quickly evolved to have more functions than just switches. Integrated LEDs and illuminated emblems are state of the art. Integrating displays or microcontrollers is making HMIs smart. In this class we will see the technological possibilities and real-life examples of integrated smart functions in HMI systems. The examples show integrated displays, touch buttons including their electronics and novel printed sensors. Furthermore, the integration of transparent heaters, antennas or shielding will be outlined as this will be the next level of integration to a smart HMI.

Screen Printed Batteries

Gunter Hübner

Stuttgart Media University

Every IOT device, sensor, display etc. etc. needs a power supply. If it is not connected by cable to a power supply, a battery or supercap is needed, preferably integrated into the device, and depending on the form factor, in the best case freely designable and most desirably flexible. Printed batteries and the corresponding supercaps offer this functionality. They differ significantly from standardised and rigid housings as known from AA, AAA or button cells. This course introduces the basic designs of printed batteries and their components. Components such as substrates, current collectors, electrodes, separators, electrolytes and sealants, sealing techniques are discussed in detail with their properties, requirements and challenges. Different electrochemical systems, non-rechargeable and rechargeable, are also discussed. Performance values are also shown.

Wearable Sensors for Healthcare Applications

TNO at Holst

Charlotte Kjellander

With rising prevalence of chronic diseases, healthcare organizations are dealing with resourcing issues, enormous pressure on personnel, long patient waiting lists, and missed health screening appointments, further pressurized by the consequences of the recent coronavirus pandemic.

This more than ever highlights a need in a sustainable healthcare from economic, social, and environmental perspective.

Wearable skin sensors or ‘the smart skin’ offer new ways for remote monitoring to support the accessibility to and sustainability of healthcare systems along the entire care cycle: from healthy lifestyle to screening, diagnosis and post treatment surveillance.

Recent advances in technology printed electronics, in miniaturization of sensors and in photonics, have significantly contributed to the wearable technology. All of these sensors can be integrated into stretchable, flexible and breathable wearables which can be worn during weeks.

In this Masterclass you will learn about the Vital Signs wearable patch – an open platform for measurements of biophysical read-outs as well as about its potential applications for remote monitoring for well-being and heath. What is more, we will share how next generation wearable technology platform can address healthcare needs. We will also address challenges on the road ahead concerning manufacturing, durability of wear and signal reliability.

3D Structural In-Mold Electronics: New Design Freedom and New Design Rules


Karthikesh Raju

In-Mold Electronics (IME) is a proven technology for bringing functionality into mechanical structures, making formerly dead spaces alive and functional. Basic IME in its simplest form - flat or mildly curved surfaces augmented with printed wiring - offers straightforward solutions for eg. for touch sensing, antennas, and heating elements.

More complex functionality requires basic IME to be augmented with existing components, such as LEDs and control systems in case of complex lighting. Design wise, IME with thermoplastic electronics substrates and plastic wirings offers a platform for thermoplastic electronics: A contemporary cost-effective solution for mass produced 3D electronics and true smart surfaces.

Integration of electronic functionalities, mechanical support, and decorative materials into a single monolithic structure instead of multiple distinct parts leads directly to drastic reduction of materials and logistics needed. Further, the additive process of printing electronics directly onto thin substrate diminishes the environmental load implied in using traditional PCBs and wet etching methods.
In the masterclass, we discuss the overall 3D structural IME solution with real-life applications and demonstrators concerning the main manufacturing and design aspects. Special emphasis is given to the changes in design rules going from traditional PCB electronics with separate mechanical parts to formable structural electronics.

12:00 PM

Technologies for High-Resolution R2R Manufacturing

Eastman Kodak

Carolyn Ellinger

The use of printing techniques to manufacture flexible electronics is now commonplace for a range of products – from consumer electronics to medical tests to automotive components. Product requirements drive choices in manufacturing techniques. This talk will review features that can be delivered by different print methos for comparison against a diverse set of end-use requirements.

There are multiple, readily available printing technologies that offer a range of addressable resolutions and obtainable throughputs (i.e. print speed). There is a further distinction between print technologies for the range of inks that can be printed, as well as the volume of ink that can be deposited in a single-pass.

We will review a high-level comparison between print technologies – mapping the technical capabilities of each to the features required for end products. Advantages of these additive R2R technologies will be covered - looking beyond the “obvious” potential materials savings over subtractive technologies for potential benefits to both the manufacturer and the end-product stakeholders.

The discussion will extend to ways to achieve the best performance from various print systems. Working examples will be primarily taken from Kodak’s high-resolution flexographic functional printing system, however broader insights will be shared. We will explore how best to take full advantage of “addressable resolution” and print speed in print systems, with attention to various process elements that must be considered and controlled.
