Biomaterials for Sustainable Technologies Development

This seminar will introduce a non-exhaustive list of biomaterials investigated by the presenter and his research team, for electronics development, biosensing and the establishment of sustainable routes for organic molecules synthesis and their degradation. The lecture will offer also insight into the immense potential of the follow up research on biomaterials. In brief, the talk will introduce:

  • Flexible natural and biodegradable substrates with high resistance to solvent exposure and temperature stability
  • Natural dielectrics: g. cellulose and cellulose derivatives, natural waxes, natural oils, natural gums, natural resins of plant and animal origin, alkaloids, nucleobases and sugars
  • The uncharted class of bio-origin, H-bonded semiconductors in the families of indigos, anthraquinones and acridones displaying state of the art performance in electronic circuits and homojunction solar cells
  • Synthetic protocols proposed to create a new generation of bio-origin/bio-derived molecules with improved performance for the development of electronics, photovoltaics, batteries and bioelectronics interfaced with living tissue
  • Functional devices fully based on benign biomaterials showing performance equaling or even surpassing the one offered by state-of-the-art, plastic based counterparts
  • Fully biocompatible and highly conducting wires and needles with tunable flexibility and dissolution characteristics, as future platforms for neural interfacing and synapse modulation
  • Bio-degradation protocols for the establishment of “green” electronics and technologies

The potential of follow-up research in the biomaterials field is immense, with large area electronics fabrication, biomedical implants, bio-sensing and smart labeling, lab-on-chip devices for function monitoring or triggering, representing only the tip of the iceberg of many more immediate possibilities of high interest for the scientific community and industry. Natural and nature-inspired materials have the unrivalled capability to create “safe-first” sustainable technologies for the benefit of mankind and environment.


About The Speaker


Dr. Mihai Irimia-Vladu was born in Craiova, Romania and obtained his B.S. in Mechanical Engineering from the University of Craiova in 1997, followed by a short employment of two years as mechanical testing engineer at Daewoo Automobiles Romania. He completed his Ph.D. under the guidance of Prof. Jeffrey W. Fergus in the field of solid-state sensing, at the Materials Engineering Department of Auburn University, Alabama in May 2006. He moved in July 2006 to Johannes Kepler University in Linz, Austria as post-doctoral fellow, working within the research groups of Prof. Serdar Sariciftci and late Prof. Siegfried Bauer. In Linz, he was the initiator and principal investigator of “green” materials (biomaterials) for organic electronics. Dr. Irimia-Vladu has been from October 2012 to May 2019 a Senior Scientist in the Department of Materials at Joanneum Research mbH, Austria where he continued his unusual research directions on biomaterials for sustainable circuits, energy conversion and bio-integrated electronics. Dr. Irimia-Vladu raised in excess of 2 million Euros in external funding, edited 1 book and authored 36 publications in peer reviewed journals, with 9 front cover highlights that received more than 2500 citations for an h-index of 21. He presented his group work through 7 tutorial/keynote, 22 invited presentations at international conferences and 19 seminars at various universities or research centers worldwide. Dr. Irimia-Vladu participated as an external member (opponent) of 4 Ph.D. defenses in Sweden, Finland and Spain. For his first worldwide demonstration of “edible electronics”, he was awarded in 2011 the “1st prize of Austrian Society for Environment and Technology” and was named “Austrian of the day” by the regional newspaper in the Upper Austria region. Among scientific discoveries that can be credited to Dr. Irimia-Vladu, is also the first report of semiconducting properties of the historic dye indigo, which helped open a new research field on hydrogen-bonded semiconductors. In April 2019 he was selected as Outstanding Alumnus of the Year by his Alma Mater Department of Materials Engineering of Auburn University, as a recognition of his contributions to the field of “Green” and Sustainable Electronics. Dr. Mihai Irimia-Vladu is an active member of American Chemical Society and Materials Research Society and coalesced the emerging field of Bioelectronics by co-organizing 5 international meetings, among them 4 were Materials Research Society symposia. Dr. Irimia-Vladu together with his wife, Marina, have 2 children, Cristian, 16 and Stefan, 10. Dr. Irimia-Vladu’s hobbies include history, hiking, karate, soccer and American football.
