Biography

 

Jonathan Rivnay is an Assistant Professor in the Department of Biomedical Engineering at Northwestern University. Jonathan earned his B.Sc. in 2006 from Cornell University. He then moved to Stanford University where he earned a M.Sc. and Ph.D. in Materials Science and Engineering, studying the structure and electronic transport properties of organic electronic materials. In 2012, he joined the Department of Bioelectronics at the Ecole des Mines de Saint-Etienne in France as a Marie Curie post-doctoral fellow, working on conducting polymer-based devices for bioelectronics. Jonathan spent 2015-2016 as a member of the research staff in the Printed Electronics group at the Palo Alto Research Center (PARC, a Xerox Co.) before joining the faculty at Northwestern in 2017. He is a recipient of the Faculty Early Career Development (CAREER) award from the National Science Foundation (2018), and a research fellowship from the Alfred P. Sloan Foundation (2019), and was named a Materials Research Society Outstanding Early Career Investigator (2020).

Design Considerations for OECT Materials, Sensors, and Circuits

 

Abstract

Conjugated polymers are ideal active materials for bioelectronic interfacing. They show significant molecular-level interaction with their local environment, readily swell, and provide soft, seamless mechanical matching with tissue. At the same time, their swelling and mixed conduction allows for enhanced ionic-electronic coupling for transduction of biosignals. Structure-transport properties allow us to better understand and design these active materials, providing further insight into the role of molecular design and processing on ionic and electronic transport, charging phenomena, and stability for the development of high performance devices. Such properties stress the importance of bulk transport, and serve to enable new capabilities in bioelectronics. In this talk I will discuss the design of new organic mixed conductors and future design rules for performance and stability. I will demonstrate how such materials properties relax design constraints and enable new device concepts and unique form factors, allowing for flexible amplification systems for electrophysiological recordings.
