Abstract
The ubiquity of IoT devices has opened new opportunities for intelligent connectivity and seamless integration into daily life. However, current IoT systems still face critical challenges in limited sensing capabilities, vulnerability in communication security, restricted compatibility across heterogeneous protocols, and the lack of personalized service delivery. In this talk, I will present my research along two main directions to address these issues. First, I enhance device-to-device sensing and communication by leveraging side-channels to expand sensing boundaries, improving communication security, and extending connectivity for legacy devices without hardware modification. Second, I explore multi-user personalized acoustic field manipulation to improve device-to-human interaction, achieving personalized audio delivery, independent sound zones, and simultaneous sensing and communication in shared environments. These contributions demonstrate how ubiquitous IoT systems can evolve from limited, isolated functions into intelligent, widely connected, and user-centered platforms.. Finally, I will envision future work on low-power sensing and communication through backscatter technologies and passive metasurface design, aiming to improve autonomy, scalability, and resilience in ubiquitous IoT systems.
