On this Friday, 19th of March 2021, and within the framework of the International Office Academy Sci-Cafe Colloquial Talks, Professor Ioanna Zergiotiin the National Technical University of Athens (http://zergioti.physics.ntua.gr/) will present her novel work in Laser Direct printing for Flexible Electronic Applications. The talk will be delivered through the zoom platform and will begin at 1000 AM CET (1100 o’clock Athens Time)
Current technological trends require the precise deposition of highly resolved features, in a direct writing approach that preserve their structural and electronic properties upon transfer while increasing the number of components that can be integrated into a single device. Over the past decade, printed electronics technology has evolved and is now used in applications such as flexible screens, intelligent labels, and packaging. Among the printing techniques, Laser-induced forward transfer (LIFT) technique is capable of printing electrical circuits quite inexpensively and quickly. At the same time, this technique is environmentally friendly and has no restrictions in terms of viscosity. In this work, we highlight the newest trends of LIFT manufacturing for the development of a variety of components with electronic, optoelectronic, and sensing functionality such as RFID antennas, RF transmission lines, organic thin-film transistors, metallic interconnects, circuits defects repairing, and biochemical sensors.
At the same time, the increasingly demanding requirements have highlighted the need for a more thorough, all-embracing research regarding the rheological characteristics of the printable fluids, their jetting dynamics, and their electrical, post-sintering properties, that will define the process’ reliability, aiming towards its industrialization.
Prof. Ioanna Zergioti is a Professor at the NTUA, School of Applied Mathematics and Physical Sciences since 2013. She studied Physics at the University of Crete and she received the degree at the Foundation for Research and Technology-Hellas and the University of Thessaly, for her work on the growth of thin nanocrystalline Carbide films and mechanisms using laser-based processes. In the frame of her Ph.D. research, she worked for the fall semester of 1996 in the Mechanical Engineering Department at the University of California, Berkeley on the LIFT process. After her PhD, she worked as a post-doctoral researcher in the Max Planck Institut für Biophysikalische Chemie in Göttingen, on Laser matter interactions studies. Then, she worked as a post-doctoral researcher at Philips CFT on Laser Sintering of sol-gels for electronics until 2000. Her main research activities are related to laser printing, patterning, sintering for organic electronics and sensors applications as well as laser-matter interaction studies. She has co-authored more than 100 publications in international refereed journals, 90 publications in conference proceedings, and 7 patents. Over the years she has gained experience in leading R&D activities in the frame of EU-funded RIA as a principal investigator (in more than 20 projects overall).
