报告题 目：Conformal, Degradable Sensors for The Environment
报 告 人：Huanyu Cheng 助理教授
主 持：李传浩 教授
Recent advances in electronics enable powerful environmental sensors that can provide continuous, in situ monitoring of various parameters in the environment with new data for the environmental science such as climate model and hazard warnings. Environmental sensors can help inform important health information for the agriculture and people that will be affected by the environment. However, recollection is required to remove the sensors from the environment after use in certain applications (e.g., monitoring of oil spill at the sea). Conventional electronics today form on the planar surfaces of brittle wafer substrates and are not compatible with the complex geometry of various structures in the environment. Therefore, stretchable and biodegradable electronics are the two missing links in the design process of disposable environmental sensors. This talk presents the challenges, mechanics, and design strategies, behind a disposable environmental sensor that (a) integrates with the complex geometry of various structures in the field, and (b) dissolves completely after its effective operation. The disposable environmental sensors will provide continuous, in situ monitoring of various environmental parameters and eliminate the need for recollection due to their environmentally benign end products.
Dr. Huanyu Cheng was appointed an Assistant Professor of Engineering Science and Mechanics (ESM) and Materials Research Institute (MRI) at The Pennsylvania State University in Aug 2015, and was awarded the Dorothy Quiggle Career Development Professor in Sep 2015. He earned a Ph.D. and a Master’s degree from Northwestern University in 2015 and 2011 respectively, and a Bachelor’s degree from Tsinghua University (China) in 2010. Prior to joining Penn State, Dr. Cheng also worked as a Visiting Research Fellow with Prof. John A. Rogers at the University of Illinois at Urbana-Champaign on stretchable and transient electronics. Throughout Dr. Cheng’s research career, he has worked on mechanics design and manufacturing of biologically inspired electronics with applications in robotics, biomedicine, and energy. Dr. Cheng has co-authored over 50 peer-reviewed publications, and his work has been recognized through the reception of awards including Forbes 30 Under 30 2017 in Science, election to the Global Young Academy, a Haythornthwaite Research Initiation Grant from ASME (2016-2018), Finalist for Forbes 30 Under 30 list in Manufacturing/Industry in 2016, Howard Hughes Medical Institute (HHMI) International Student Research Fellowship, Best Paper Award in ASME Applied Mechanics Division Student Paper Competition, International Institute for Nanotechnology Outstanding Researcher Award, Chinese Government Award for Outstanding Self-financed Students Abroad, and many others. He also serves as associate editor for Computers in Biology and Medicine, editorial board member for Informatics in Medicine Unlocked, and reviewer for over 40 international journals.
