MS&E Seminar: Professor J. Devin MacKenzie

Scalable and Ultrahigh Resolution Printing of Flexible Electronics and Energy Devices

J. Devin MacKenzie, Associate Professor
Department of Materials Science and Engineering, University of Washington

The intrinsic nature of flexible electronics applications: flexibility, robustness and scalability to large areas, presents new opportunities and challenges for manufacturing. Flexible electronics are well suited to low capital and low operating cost manufacturing approaches such as large area printing, sub-micron capable electrohydrodynamic inkjet printing and roll to roll processing on flexible, larger and low cost substrates at high throughputs. To date, to enable these manufacturing approaches, there has been considerable focus on new materials and unit processes. To scale the production of flexible electronic and energy devices with high yield, however, other key elements also need to be addressed before and during processing. This includes rapid feedback in-situ process monitoring based on the new functional property targets of these materials that have not been used in traditional printing and flexible circuit manufacturing. In this talk, we will cover current and future work at the University of Washington on photophysical in-situ process monitoring and machine learning-enable feedback and design for roll to roll manufacturing. The presentation will also touch on how numerical techniques and learning algorithms can be applied to rapidly optimize the processes and guide device design to better achieve desired performance outcomes quickly. Lastly, examples of recent work covering the growing range of emerging applications for printed and flexible electronics materials and devices in our open access lab at UW will be presented: power systems to drive mobile and compact truly flexible electronics that can be manufactured at low costs, highly stretchable sensing for artificial tissue, and new low temperature, solution processed, high piezoelectric coefficient organic perovskite derivatives for printed vibrational sensors and harvesters.
