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 nanoand 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 industrystandard 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. Degree 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. In 2001-2003, he joined micro electromechanical systems (MEMS) group at Jet Propulsion Laboratory (JPL) which is one of NASA center as a member of engineering staff. In 2003, he joined the Department of Chemical and Environmental Engineering at University of California-Riverside and served as the Department Chair from 2011-2017. He was the founding director for UC-KIMS Center for Innovative Materials for Energy and Environment and currently serving as the Specialty Chief Editor for Frontiers of Chemistry, Electrochemistry Section. Starting Fall 2020, he joined the University of Notre Dame as the Bernard Keating Crawford endowed professor in the Chemical and Biomolecular Engineering Department. In 2022, he was elected to be the Fellow of National Academy of Inventors. Additionally, he received a numerous awards including 2019 Engineer of Year Award from Korean Government, 2018 ECS Electrodeposition Division Research Award, KIChE President Award, Brainpool Fellow from Korean Government, University of California Regent Fellowship, Jet Propulsion Laboratory Spot Award, Abner Brenner gold medal award from American Electroplaters and Surface Finishers Society (AESF), First time author’s award from Plating and Surface Finishing, National Science Foundation graduate fellowship, and Department of Education fellowship. Dr. Myung’s research interests are focused on the synthesis of nanoengineered materials and apply these materials in various advanced applications including spintronics, biological and chemical sensors, electronics, optoelectronics, energy harvesting, and environmental remediation. Dr. Myung’s group objective is to control nanoscale sized features to enhance material properties and device functions beyond those that we currently know. Currently, he publishes over 280 peer-reviewed journal papers, and his h-index is 68 with the total citation of over 16,500.
