Creation of 3D smart objects through IME involves high pressure-temperature processes. Saralon GmbH produces thermoformable inks for printed electronics that withstand such conditions without sacrificing functionality.

Electronic devices continue to evolve. Flexible, stretchable, and deformable electronic devices constitute a growing topic of interest for a wide variety of application fields such as in safety, medical, sport or automotive fields. Encres Dubuit is now active in this field by working on the development of innovative bio-based inks specifically designed for printing flexible, conformable and stretchable electronic devices.
These inks, suitable for screen-printing, are based on silver and cellulosic materials. This biobased matrix is interesting thanks to its non-toxicity, its natural abondance and its specific outstanding properties. Regarding ink development, the bio-based matrix helps to disperse and
stabilize active particles. It is also used as a rheological agent to meet the printing processes requirements and acts as an adhesion promoter concerning the interaction with the substrate.
These innovative materials are used to develop stable conductive inks with different scope of application. Flexible transparent conductive inks with high opto-electrical properties without. any sintering have been first developed. Then, to go beyond flexibility, an ongoing project specifically focuses on stretchability by designing a stretchable cellulose-based binder for the ink. This innovative approach tends to develop the next expected generation of inks. The challenge is to maintain the percolation between the active particles within the ink film while minimizing the electrical properties variations under strains applied to printed device.
This stretchable technology of ink could be transposed to other systems including colored pigments or active materials (conductive, sensitive, etc) to confer stretchable features for a wide range of applications.

How to make sure skin electrodes stays attached on the skin and patient monitoring is reliable without disruption from the adhesive detaching from the skin. Skin adhesive testing have many consideration and one biggest is how to evaluate adhesion durability by using an alternative test surface than skin. Testing skin adhesive on human subject brings other clinical study requirements and ethical committee approval to the table. This presentation will explain different testing methods to evaluate the skin adhesive performance mechanically on laboratory test setting and as well on human skin.

BotFactory will present an overview of the possibilities of generative AI, and how it is making strides in the world of electrical engineering. As part of the presentation, BotFactory will showcase some of the latest innovations on Supervised Additive Manufacturing to achieve fully automated production, testing and correction of PCB boards, to achieve the speed requirements of our AI enabled era.

With nearly 28 billion RFID tags sold in 2021 and a yearly growth of 36%, the sheer volume of these tags will result in significant environmental challenges, due to the wasteful and resource intensive nature of current production methods. At Voltera, we set out to additively print an RFID tag using copper nano ink on paper, resulting in a compostable RFID tag that created no copper waste or toxic chemical byproducts from the production process.

Currently, print conductivity is typically measured at the end of production with physical probes, which is the most common quality control tool in printed electronics facilities today. These probes are broadly used to test both the printing process and the final devices but are slow and potentially damaging to the ink. Camera inspection systems are common in the graphic printing field, and work at the speed of the production line, but do not measure the functional properties of the ink. We will discuss the current needs and open problems in printed electronics quality control and present a solution in TRAQC. The TRAQC system is able to run at the speed of the production and is able to extract ink functionality (conductivity) and geometrical variation (spreading/stretching), the key parameters for electronics printing, in-line and at-speed.
