The Internet of Things (IoT) has the potential to revolutionize our world by connecting the physical and digital worlds. However, its current reliance on battery-powered devices limits scalability and raises environmental concerns. My research aims to overcome these challenges by developing battery-free, cost-effective IoT solutions, necessitating a rethinking of wireless networking. In Consumer IoT, I focused on ultra-low-power communication with novel radio architectures and an asymmetric communication scheme that enables existing Wi-Fi infrastructure to connect IoT devices. In Industrial IoT, I addressed reliability with a magnetic RFID system and robust RFID localization design, reducing object identification errors. These innovations resolve reliability issues that have hindered battery-free RFID adoption in the industry. Additionally, I've contributed to massive MIMO millimeter-wave software-defined radio and wireless brain-machine interfaces, opening new possibilities for next-gen IoT applications. By building on these innovations, we can unlock the potential of battery-free IoT, the Internet of Bodies, and experimental wireless infrastructures, offering a robust, sustainable, and scalable IoT future.
