Integrated Wireless Power, Data Communication, and Thermal Sensing Systems for Autonomous Multisite Brain Implants

Mohammad Javad Karimi received a Bachelor’s degree in Electrical Engineering with a major in Electronics from the Sharif University of Technology in 2019. He received a Ph.D. degree in the Department of Electrical and Micro Engineering at the Swiss Federal Institute of Technology Lausanne (EPFL), Lausanne, Switzerland. His research focused on RF CMOS design, low-power analog circuits, and wireless power transmission in biomedical applications.Catherine Dehollain received the Master’s degree in electrical engineering and the Ph.D. degree from École Polytechnique Fédérale de Lausanne (EPFL), Lausanne, Switzerland, in 1982 and 1995, respectively. From 1982 to 1984, she was a Research Assistant at the Electronics Laboratories (LEG), EPFL. In 1984, she joined the Motorola European Center for Research and Development, Geneva, Switzerland, where she designed integrated circuits applied to telecommunications. In 1990, she joined EPFL as a Senior Assistant at the Chaire des Circuits et Systemes, where she was involved in impedance broadband matching. Since 1995, she has been responsible for the RFIC Group, EPFL, for RF activities. She has been the Technical Project Manager of the European projects, Swiss CTI projects, and the Swiss National Science Foundation projects dedicated to RF wireless micro-power sensor networks and mobile phones. Since 1998, she has been a Lecturer at EPFL in the area of RF circuits, electric filters, and low power CMOS analog circuits. From 2006 to 2014, she was a Maitre d’Enseignement et de Recherche (MER) at EPFL. From 2014 to 2021, she has been an Adjunct Professor with EPFL. Since 2022, she is an Honorary Professor with EPFL. She is the author or co-author of seven scientific books and 190 scientific publications. Her current research interests include biomedical remotely powered sensors, RFIDs, RF circuits, low-power analog circuits, and electrical filters. Alexandre Schmid (Senior Member, IEEE) received the M.Sc. degree in microengineering and the Ph.D. degree in electrical engineering from the Swiss Federal Institute of Technology (EPFL) in 1994 and 2000, respectively. He has been with EPFL since 1994 and has been conducting research in the fields of bioelectronic interfaces, biomedical and implantable microelectronics, non-conventional signal processing (machine learning, AI) and neuromorphic hardware, and reliability of nanoelectronic circuits. Since 2011, he has been a ‘‘Maître d’Enseignement et de Recherche’’ (MER) Faculty Member of EPFL. Since 2024, he is a Visiting Professor at Hokkaido University, Sapporo, Japan. He is a coauthor and co-editor of five books, and over 190 articles published in journals and conferences. He has served as the General Chair for the Fourth International Conference on Nano-Networks in 2009, and as an Associate Editor for the IEICE Electronics Express (2009-2014).
