The Internet of Things (IoT) plays a critical role in connecting society to the digital world. Billions of IoT devices are used today to enable applications from smart homes and cities to digital healthcare and smart agriculture. While we have seen significant benefits, to fully realize the potential of these systems we need to address a key challenge: enabling power and connectivity for resource-constrained environments.  How can we collect data in remote forests, farms, or even oceans where there is no Internet connectivity or access to power? 
In this talk, I will present two examples of my research that address this challenge. First, I will present FarmBeats, a system that enables seamless data collection by using new technologies such as TV White Spaces for communication and low-power sensors for data collection. FarmBeats is designed to enable data-driven agriculture techniques for farms that are located in areas that lack power and connectivity infrastructure. I have deployed the FarmBeats system across the United States and Europe, and we have demonstrated that the system can provide significant benefits for farms in the form of cost savings and productivity. Finally, I will present the design and implementation of a low-power passive wireless communication system that does not rely on ambient or generated RF signals and instead modulates Johnson (thermal) noise.


Zerina Kapetanovic is an Assistant Professor in the Department of Electrical Engineering at Stanford University working in the area of low-power wireless communication, sensing, and Internet of Things (IoT) systems. Prior to starting at Stanford, Kapetanovic was a postdoctoral researcher at Microsoft Research in the Networking Research Group and Research for Industry Group. She received her Ph.D. in Electrical Engineering from the University of Washington in 2022.
