Abstract: With the ever-increasing demand for the Internet of Things (IoT), sensors, and autonomoussystems, the development and advancements of interfaces for energy harvesting, wirelesscommunication, and power delivery have become even more crucial. This seminar will highlightthe prospective challenges and unique approaches to developing an integrated solution for awireless and batteryless system for three different case scenarios. The first part of the seminarwill detail a miniaturized implantable wireless neural signal recording and optogeneticneuromodulation system with an inductive-coupling-based wireless powering scheme for thenext generation of neuroscience research. Followed by that, a far-field wireless power transfer(WPT) network for UAS (Unmanned Aerial System) incorporating waveform engineering,electromechanical beamforming, and integrated ultra-wideband phased-array antenna will bepresented. Lastly, a liquid-based energy harvesting concept called reverse electrowetting will beintroduced that can not only harvest energy from low-frequency movement but also act as a self-powered motion sensor to detect various motion activities, such as walking and running.

Bio: Dr. Ifana Mahbub is an Assistant Professor in the Department of Electrical Engineering at theUniversity of North Texas (UNT), where she is leading the Integrated Biomedical Circuits and SystemsLaboratory (iBioCASL). Her research interests include energy-efficient integrated circuits and systemsdesign for read-out, wireless communication, and wireless power transfer for various implantableand wearable sensors. Her recent research interests also include ultrawideband/mm-wave phased-array antenna design for far-field wireless power transfer/V2V communication for UAVs.
