Dr. Hao Ren obtained his bachelor’s degree in Mechanical Engineering from University of Science and Technology of China, Heifei, China, in 2004. Afterwards he moved to Institute of Optics and Electronics, Chinese Academy of Sciences and obtained his master’s degree in Optical Engineering in 2011. Upon graduation, he moved to the United States and obtained his Ph. D in Electrical Engineering from Arizona State University, Tempe, AZ, U.S.A. in 2016. Since graduation, he has continued his study in Arizona State University as a Postdoctoral Researcher. He joined School of Information Science and Technology, Shanghaitech University in September 2018.
During his postdoctoral study, he is mainly working with Prof. Junseok Chae of Arizona State University, on fully passive wireless telemetry for pressure sensing, wearable sensors for asthma sensing, piezoelectric blood viscosity sensors, MEMS microbial fuel cells and supercapacitors. He worked on MEMS microbial fuel cells and supercapacitors and wireless inductive coupling systems on a flexible substrate during my Ph. D study with Prof. Junseok Chae. He worked on MEMS micromirror and out-of-plane actuators during his master’s study.
He published 24 peer-reviewed journal papers in Nano Energy, Biosensors and Bioelectronics, Journal of Power Sources, Nanoscale, IEEE Transactions on Power Electronics, Environmental Science and Technology, ChemSusChem, Scientific Reports, Microfluidics and Nanofluidics, Journal of Micromechanics and Microengineering, etc. Of them, 11 papers are first-authored, one first-authored journal paper has an impact factor >13.1 and four first-authored journal paper has an impact factor >6.9. He also published 5 first-authored conference papers in top international conference in MEMS area (3 IEEE MEMS and 2 IEEE Solid-State Sensors and Actuators Workshop). He is the recipient of the Best Poster Award Finalist in IEEE MEMS 2013. He also published 5 first-authored book chapters in Wiley-VCH, Elsevier, CRC Press, Springer. He is a reviewer for journals including Advanced Energy Materials, Biosensors Bioelectronics, Nanoscale, IEEE Journal of Emerging and Selected Topics on Power Electronics, ACS Applied Materials and Interfaces, Sensors and Actuators, ChemSusChem.
During his Ph. D study, he achieved a world record current and power density in all microbial fuel cells since 2014 (among 3000 journal papers). In 2016 he further improved the world record current and power density by 3 fold. During the same period, he presented the first microbial supercapacitor in the world and improved the current and power density by one order of magnitude.
