The Office of the Vice President for Research is pleased to host the next Nano@Wayne seminar on Tuesday, April 10, 2018 from 2:30 to 3:30 p.m. in the EDC Auditorium, Room 1507, in the College of Engineering Building. The seminar is free and open to the public. Registration is requested.

The Nano@Wayne Seminar Series presents, "New Materials and Printing Processes for Flexible Electronics" with C. Daniel Frisbie, Ph.D., professor and head, Department of Chemical Engineering and Materials Science, University of Minnesota. Dr. Frisbie also is the Distinguished McKnight University Professor at the University of Minnesota. He obtained a Ph.D. in physical chemistry at MIT and was an NSF Postdoctoral Fellow at Harvard. His research focuses on materials for printed electronics, including organic semiconductors and their applications in devices such as transistors and electrochromic displays.

Abstract:

Currently there is great interest in developing manufacturing methods for integrating electronic circuitry into flexible and stretchable substrates for a spectrum of applications including roll-up displays, wearable biosensors, smart labels, and electronic skins (‘e-skins’) for robotics, for example. One fabrication strategy that has captured imaginations involves the use of digital or analog printing techniques to pattern electronically functional inks onto paper, plastic, rubber, or metal foils. However, “printed electronics” has a number of significant challenges, including spatial resolution, pattern registration, and printed circuit performance. In this talk, I will describe a multi-pronged approach to address these challenges that may bring roll-to-roll printed electronics closer to reality. To begin, I will show that innovations in materials allow the fabrication of printable, low voltage thin film transistors (TFTs), the key building blocks of flexible circuits, and that these can be incorporated into simple printed circuit demonstrations involving two dozen TFTs and an equivalent number of printed resistors and capacitors. The second half of the talk will describe a novel liquid-based fabrication approach that we term SCALE, or Self-Aligned Capillarity-Assisted Lithography for Electronics. The SCALE process employs a combination of digital printing and in-substrate capillary flow to produce self-aligned devices with feature sizes that are currently as small as 1 mm. The talk will finish with a discussion of the new opportunities in flexible microelectronics afforded by liquid-based processing.  


A short reception will immediately follow the seminar.
