Abstract: Energy harvesting system-on-chip devices are emerging as the most promising solution for future wireless sensing with applications in medical implants and IoT. On one side, energy extraction from ambient sources facilitates permanent powering techniques required for long-term operation. On the other side, the high integration capability of commercial CMOS technology opens the opportunity for a high-resolution sensing and data communication with a compact form-factor. My research builds a foundation for joint wireless power delivery, low-power sensing, and wireless communication in such highly integrated systems yielding a paradigm shift in the design and development of future ubiquitous low-power wireless systems.

In this talk, I will present the world’s most power-efficient wireless transceiver with an integrated wireless power delivery system. We demonstrate a fully on-chip operation and utilize two sets of loop and dipole antenna for wireless power delivery and data communication, respectively. I will explain how we achieve a 150 Mbps uplink communication data rate under a stringent power budget by introducing a novel power management technique. I will then, discuss the opportunities offered by this platform to enhance next generation IoT and medical devices. In particular, we tackle the limited operating range by forming a synchronized distributed sensor network built from fully-on-chip integrated systems. Also, we address the power scarcity challenges in biomedical/environmental sensing by adopting extensive low-power design techniques and exploiting machine-learning-assisted sensing. This interdisciplinary research direction incorporators advancements such as applied physics, machine learning, healthcare, and wireless networking.
