Doctoral Thesis: Passive Health Monitoring with Radio Waves — In Body and In Home

Current health care is primarily in-clinic, episodic, and semi-empirical. With the development of intelligent devices such as smartphones, smartwatches, and more cutting-edge devices such as smart in-body devices and smart contactless in-home sensors, we are beginning to see a paradigm shift in health care. Health care is becoming more embedded in daily life, using more continuously collected data and making more data-driven decisions. In this talk, I will talk about two of my research in this direction: One on our system to do deep in-body communication and localization using a backscatter scheme, which is solving the critical challenges of near-zero-power in-body continuous monitoring; Another is our work on digital biomarker based on passive measured in-home unscripted daily gait speed data from our smart contactless in-home sensors, which shows how new daily continuous monitored health-related data, can help us transform the way we assess Parkinson’s disease severity, motor fluctuation, and progression.
