Jessica Wu, a junior NSF REU student, developed a robust inking and drying system for a continuous roll-to-roll (R2R) microcontact printing process, ultimately to achieve advancements in the quality-controllable, large-scale R2R printing of flexible electronics. This technology was presented in the NSF REU poster competition in the IMECE on Nov. 01-05, 2021, and won Best Presenter Award. Ph.D. student, Jingyang Yan mentored Jessica Wu for partial fulfillment of his research project in scale up and quality control of the R2R microcontact printing process. The research project is aimed to achieve high-precision printing and comprehensive micro-scale pattern transfer with reasonable, industry-scale printing speeds, with decreased cost printing results from standard practices. We would like to thank the NSF program directors (Grant: NSF GOALI CMMI-1916866) for funding this REU research.
