Within this context, thermoelectric materials, i.e. materials capable of recycling waste heat through its partial conversion to electrical power, have attracted considerable attention in the last twenty years[1]. Organic semiconductors (OSCs), such as conjugated polymers and small molecules, have recently become a blooming field of research in the continuous search for potential candidates for the fabrication of thermoelectric systems. Indeed, OSCs possess some important advantages compared to their inorganic counterparts, in particular their processability at room temperature in liquid phase using printing fabrication techniques and their excellent mechanical robustness and flexibility [2][3].
At the PRINT’UP institute, we developed a fabrication and characterisation protocol for all-printed organic thermoelectric generators, fabricated on flexible polyimide substrates. Each generator is composed of two semiconducting legs, one p-type doped and the other n-type doped, electrically con...

#PrintedElectronics #MultiMaterialPrinting #LaserPrinting #Disruption #AdditiveElectronics Author: Masoud Mahjouri-Samani | CEO and Founder NanoPrintek, info@nanoprintek.com In labs across the world - whether in industry, government, or academia - there’s a shared frustration: the path from concept to product is too slow, too expensive, and often restricted by the limitations of the tools themselves. For decades, R&D and Production labs have had to work around the constraints of ink-based printing systems - formulating complex inks, fighting clogs and contamination, dealing with post-processing steps, and adapting their ideas to match the tool rather than the other way around. At NanoPrintek , that paradigm is being reimagined.

Figure 1. The paradigm is being reimagined. NanoPrintek’s ink-free multimaterial printing platform  doesn’t just eliminate inks - it eliminates the compromises that come with them. Instead of using liquid formulations with short shelf life and questionable reliability, NanoPrintek’s technology prints directly from solid pellets of the desired material — metal, ceramic, dielectric, or composite. Using a combination of laser-induced nanoparticle generation  and real-time laser sintering , the platform creates pure, high-performance printed features right where you want them - on many substrates. There’s no drying time, no curing stage, and no solvents to remove. What you get is a clean, fast, and incredibly versatile system that can take you from ...

The Evolution of the Semiconductor Industry and Its Path to Sustainability Author: Elisa DUQUET, Hummink, elisa.duquet@hummink.com The semiconductor industry is one of the most complex, dynamic, and technologically advanced sectors in the world. It plays an essential role in shaping modern life, serving as the foundation for everything from smartphones and MRI machines to kitchen appliances and space shuttles. In today’s digital world, nearly every device we rely on is powered by semiconductor chips. The demand for semiconductor chips has reached unprecedented levels. According to the Semiconductor Industry Association (SIA), the industry shipped a record of 1.15 trillion semiconductor units last year, this figure means that every person on earth could receive over 150 chips annually. In addition, the SIA announced that the global semiconductor sales hit $627.6 billion in 2024, an increase of 19.1% compared to 2023. The semiconductor industry is projected to reach over $726.73 billion by 2027. We are Exhibiting! Visit our booth at the TechBlick event on 11-12 June 2025 in Boston . Contact us for your special discount coupon to attend (elisa.duquet@hummink.com) As production scales up to meet increasing demand, so does the need for sustainable solutions to manage waste and defective components. Indeed, the twelve largest semiconductor manufacturers together generate about 2.7 million tons of waste annually - about as much as 5 million EU citizens. Nearly 50 percent of the ...

Author: Steve Paschky Saralon now offers new ink sets for stretchable membrane switches, heaters, and electroluminescent display printing. Each of these sets contains all the essential ink components tailored to each application, simplifying your work for a seamless, high-quality experience. We are Exhibiting! Visit our booth at the TechBlick event on 11-12 June 2025 in Boston Last year, I wrote about our range of stretchable Saral Inks , designed for different substrates with various formulations like silver, carbon, and others. Since then, technology has continued to evolve, and so have the needs of the industry. We’ve been hearing from customers that they need stretchable inks that are not only conducting but also provide features like heating and capacitive touch, all while withstanding dynamic forces like bending, stretching, and twisting. One of our major focuses at Saralon has been on providing "ink sets"- collections of compatible inks that are designed for specific applications of Printed Electronics (PE). This approach aligns with our company’s mission: Simplifying Electronics Through InkTech. PE devices often require printing multiple layers of ink on top of each other, and one common challenge for developers is finding the right combination of inks that work well together. That’s where our Saral Inks Sets come in. For specific PE applications, we offer complete sets of inks that are compatible with one another, easy to print, and ensure a trouble-less printing pro...
