Abstract:
Electronic detection of gaseous molecules is rapidly emerging as an alternative to the conventional detection methods because of the small size, low-power consumption, and improved sensing performance. In this presentation, we will discuss the development of smart electronic-nose (E-nose) systems with superior sensing performance. To mimic biological olfactory systems, we optimized the high-density sensor array architecture by vertical integration of unique combinations of libraries of nanoengineered materials to identify and quantify target analytes where the sensing performance was maximized by nano- and defect- engineering of materials. Once sensor response data has been collected using high-throughput screening systems, machine learning techniques were utilized to select the optimal subset of sensor elements for detecting analytes. Manufacturability of devices were demonstrated by prototyping a wearable E-nose watch using a combination of industry-standard printed circuit board manufacturing techniques and proven, scalable, additive manufacturing techniques developed in our lab.

Professor Nosang Vincent Myung received his B.S., M.S., and Ph.D. degrees in Chemical Engineering from the University of California, Los Angeles in 1994, 1997, and 1998, respectively. He spent three years as a research engineer at the same institution. From 2001 to 2003, he joined the micro-electromechanical systems (MEMS) group at the Jet Propulsion Laboratory (JPL) as a member of the engineering staff. In 2003, he joined the Department of Chemical and Environmental Engineering at the University of California, Riverside, and served as the Department Chair from 2011 to 2017 and found UC-KIMS Center for Innovative Materials for Energy and Environment.
Starting in Fall 2020, he joined the University of Notre Dame as the Bernard Keating Crawford Endowed Professor in the Department of Chemical and Biomolecular Engineering and founded the ASEND core facility. In 2025, he also founded the ND Sensor Initiative to translate fundamental science into devices for real-world applications.
Because of his contributions to sensor technology, he was elected as a Fellow of the National Academy of Inventors in 2022 and a Fellow of the Electrochemical Society in 2025. Additionally, he has received numerous awards, including the 2019 Engineer of the Year Award from the Korean Government, the 2018 ECS Electrodeposition Division Research Award, the KIChE President Award, the Brainpool Fellowship from the Korean Government, the University of California Regent Fellowship, the Jet Propulsion Laboratory Spot Award, the Abner Brenner Gold Medal Award from the American Electroplaters and Surface Finishers Society (AESF), the First-Time Author’s Award from Plating and Surface Finishing, a National Science Foundation Graduate Fellowship, and a Department of Education Fellowship.
Dr. Myung’s research interests are focused on the synthesis of nanoengineered materials and their use in various advanced applications, including spintronics, biological and chemical sensors, electronics, optoelectronics, energy harvesting, and environmental remediation. Dr. Myung’s group aims to control nanoscale features to enhance material properties and device functions beyond current capabilities. To date, he has published over 300 peer-reviewed journal papers, holds an h-index of 74, and has accumulated over 20,000 total citations.
