Three Students Win Awards at ASME Conference

Jessica Wu and Peter DiMeo

Jessica Wu and Peter DiMeo 

Three students of Assistant Professor Xian Du of the Mechanical and Industrial Engineering (MIE) Department won impressive awards at the recent 2021 International Mechanical Engineering Congress and Exposition (IMECE), sponsored by the American Society of Mechanical Engineers.

MIE undergraduate Jessica Wu and her mentor, MIE Ph.D. student Jingyang Yan, won the Best Presenter Award in the National Science Foundation (NSF) Research Experience for Undergraduate (REU) Poster Competition. Meanwhile, MIE undergrad Peter DiMeo won Third Place in the NSF REU Poster Competition. DiMeo also won First Place in this same competition during the 2020 version of the IMECE conference.

Du's research in his Intelligent Sensing Lab focuses on the scale-up of flexible electronics printing processes from lab to industry using high-precision, in-line inspection and pattern-recognition technologies for large-surface quality control. He also works on automatic, high-resolution, accurate, and robust imaging tools for medical devices for noninvasive detection and description of biomarkers. 

The winning presentation of Wu, a junior NSF REU student, described a robust inking and drying system for a continuous roll-to-roll (R2R), microcontact, printing process, whose ultimate purpose is to achieve advancements in the quality controllable, large-scale, R2R printing of flexible electronics.

The winning poster presented by Wu and Yan was titled “Design and Test of an Inking System for Roll-to-Roll Microcontact Printing.”  

Wu’s research project is aimed at achieving high-precision printing and comprehensive micro-scale pattern transfer with reasonable, industry-scale, printing speeds, including decreased cost and improved printing results from standard practices. Her research was carried out with the support of Du’s grant from the NSF program in Opportunities for Academic Liaison with Industry.

DiMeo, a senior NSF REU student, integrated high-speed, passive, autofocus control of high-magnification lenses using nanometer precision piezo actuation. The research is based on DiMeo’s research report on the poster that won First Place in the NSF poster competition at IMECE 2020 and his recent research paper published in Optics Express.

This research project is aimed at solving the focus problems in imaging high-precision targets, such as nano- or micro-scale printed patterns in R2R, as part of high-dynamic scenarios that require incredibly fast and precise position control of high-mass and high-magnification lenses.

The title of DiMeo’s poster was “High-Speed Passive Autofocus Control of High-Magnification Lenses Using Nanometer Precision Piezo Actuation.” DiMeo’s research was supported by Du’s prestigious NSF Faculty Early Career Development (CAREER) Program.
