Title: Seamless Wireless Charging: A Game-Changer for Smart Cities
Abstract:in this presentation, we present the vision of “seamless wireless charging”. It is conceived that seamless charging, similar to what we have today with Wi-Fi for mobile internet, is possible. The technology is there to make it happen and we believe this will be a game changer for smart homes, offices and cities.
We make use of wireless power transfer (WPT) which provides inherent electrical isolation and completely eliminates the existing high-tension power transmission lines, cables, and towers. It reduces board charging cost, weight and volume. Nevertheless, WPT, for say IoT devices or EVs, poses additional challenges and sustainability trade-offs.
To meet the challenges, we present a system , method , and device that provides power to an electrical unit such as an Internet of Things ( IoT ) device or an electric vehicle (EV) that includes a transmitter that provides power through electromagnetic waves , a receiver , an array that includes a plurality of metamaterial elements , such that the electrical power passes wirelessly from the transmitter to the array , and a smart controller that applies selective phase shifts to each of the metamaterial elements such that the power is transmitted from the transmitter , reflected off the array, and is received in phase at the receiver which converts the electromagnetic waves to an electric current to power the device. If the device moves, it sends a pilot signal to the transmitter which alerts the smart controller to adjust the reflected waves in real-time such that they are always received in phase. The harvested RF power is then converted to DC to charge the device using an appropriate rectenna circuit. We will present the details of the proposed system. Will also review some of the existing and emerging technologies for the wireless charging of IoT devices or EVs when stationary or on the move.
Biography: Mohammed Ismail a prolific author and entrepreneur in the fields of system-on-chip design and test and nanotechnology, spent over 30 years in academia and industry in the US and Europe. He is professor and Chair of the Electrical and Computer Engineering Department at Wayne State University and the Founding Director of the WINCAS Center of Excellence. He is one of the world pioneers in the field of CMOS design of analog, mixed signal and RF integrated circuits and has graduated over 55 PhD students and more than 100 MS students, thesis option.
Prior to joining Wayne State in December 2016, he was a Professor at the Ohio State University in Columbus, Ohio for 20 years and held several appointments in Sweden with KTH, Finland with Aalto University and Nokia Research Center, Norway with NTH and University of Oslo, The Netherlands with Twente University, Japan with Tokyo Institute of Technology and the UAE with Khalifa University. His current research focuses on CMOS analog, RF and mm-wave Integrated circuits, Systems-on-Chip (SoCs) for the Internet of Things (IoTs), Chipsets for 5G/6G wireless communications, automotive electronics, autonomous vehicles and RF energy harvesting solutions for wireless charging.
He cofounded several starts ups, including Spirea AB in Stockholm, Sweden, Firstpass Technologies and Micrys Corp in Columbus, OH and ANACAD in Cairo, Egypt (now part of Siemens) and has led a research team that developed the first CMOS combo 802.11a/b/g Wi-Fi Radio chip. More recently He developed with his colleagues the world first self-powered wearable CMOS device that predicts the onset of a heart attack using advanced machine learning algorithms. He authored or co-authored 23 books and over 200 journal publications, 300 conference papers and has 17 US patents granted and several pending.
Prof. Ismail is the Founding Editor of the Springer Journal of Analog Integrated Circuits and Signal Processing and serves as the Journal's Editor-in-Chief. He served the IEEE in many editorial and administrative capacities. He is the Founder of the IEEE International Conference on Electronics, Circuits and Systems (ICECS), the flagship Region 8 Conference of the IEEE CAS Society and a Co-Founder of the IEEE International Symposium on Quality Electronic Design (ISQED). He received the US Presidential Young Investigator Award from the White House, the Ohio State Lumley Research Award four times, in 1992, 1997, 2002 and 2007 and the US Semiconductor Research Corporation's Inventor Recognition Award twice as well as several best paper awards. More recently, he received the 2018 UNESCO Medal for contributions to nanoscience, Paris, France and the SRC Board of Director Special Recognition for Leadership of Semiconductor Research in the UAE. He is a Fellow of IEEE.
