The field of printed electronics has been gaining momentum within the last decades, where more and more printed components are finding their way to the market. Products such as sensors and electrodes, RFID tags, diaper sensors and even golf sensors are already on the market, all being enabled through printed electronics production processes on flexible substrates. The main benefits of printing electronics are faster prototyping, the ability to print on flexible and potentially cheap substrates, such as polymers and even paper, as well as scalability to Roll-to-Roll production. Current printed electronics processes are based on analogue printing technologies, such as screen printing, gravure and flexography printing. These technologies are industrially mature, and are optimized for high volume production, however have limitations in terms of large changeover times and costs as well as large waste production.

The Danish Technological Institute (DTI) has identified the demand and the bottlenecks within printed electronics and is working within production of nano-materials for electronic ink formulation as well as digital ink-jet printing of electronic components. Digital production technologies, such as ink-jet, require nano-material based conductive and dielectric inks, which can improve electrical performance, reducing printing materials by over 50% and produce little or no waste.  Furthermore, digital production lines will have zero changeover times, enabling mass customization of electronic components. DTI is working together with other research and technology organization within Europe with the vision to create a printed electronics test bed, which will give companies both technological, economical and resource services, which can provide both component prototypes as well as information on how to bring the technology to market. DTI will present the opportunities and barriers within digital printed electronics as well as the latest strides and developments within the field.

Biography
Zachary J. Davis has a background within electronics and MEMS production technologies within the last 18 years. Zachary obtained his MSc in applied physics in 2000 and a PhD within electrical engineering in 2003 from the Technical University of Denmark (DTU), both focused on fabrication of silicon based sensor systems. Zachary then worked for EPSON as project leader developing a 434MHz MEMS oscillator, gaining knowledge within industrial level development and production. In 2006, Zachary became an associate professor at DTU leading a group developing MEMS resonator based sensor systems.  Zachary joined the Danish Technological Institute in 2011, focused on production of high fidelity surface acoustic wave (SAW) components and clean room processing and production technologies and later, in 2016, started a group focused on digital based printed electronics as well as development and manufacturing nanomaterials for printed electronics.  In 2017, DTI invested over 7 Mdkk in a new laboratory and state-of-the-art digital printing platform. Zachary is author of 43 ISI publications, two book chapters, four patents and over 50 other scientific publications.
