Title: The Past, Present, and Future of Energy Harvesting Computing SystemsSpeaker: Jeremy Gummeson (University of Massachusetts Amherst)
Abstract: The last 15 years have seen tremendous research activity in resource-constrained energy harvesting systems. Early examples of work in this space focused on photovoltaic energy harvesting paired with batteries that smooth diurnal variations in solar energy; however the last decade has seen increasing interest in computing systems that have minimal energy storage capacity and are instead optimized for low energy harvesting rates, whose temporal dynamics are often unpredictable giving rise to the term "intermittent computing". In this talk I will give an overview of a decade of systems research that has looked at how we can build compelling applications that operate on these intermittently available energy resources. The first part of the talk will focus on computational RFIDs and how they can be used for continuous sensing workloads. The next part of the talk will focus on systems that are powered from energy harvested from near field communications (NFC), which includes energy harvested from mobile phones or from a 'tap' against a stationary reader. The final part of the talk will focus on recent and future work that includes leveraging emerging fully integrated passive RFID sensor tags and energy exchanges between wearable devices through the user's skin.
Biography: Jeremy Gummeson is an Assistant Professor of ECE at the University of Massachusetts Amherst. His research is multidisciplinary in and looks at how we can co-design computer hardware and software to enable energy-efficient mobile computing systems that can accurately sense humans and the world that surrounds them. More specifically, his current research largely focuses on developing novel sensing and communication techniques that enable closed-loop energy efficient systems for human-in-the-loop and autonomous applications. Prior to joining UMass Amherst, I had appointments at Disney Research and HP Labs where I worked on a number of projects spanning several broad categories of wearable devices and IoT applications. Jeremy Gummeson received his PhD in Computer Systems Engineering from the University of Massachusetts, Amherst in 2013 and was co-advised by Deepak Ganesan (CS) and Tilman Wolf (ECE). His dissertation focused on reducing dependencies on batteries by exploiting energy harvesting to enable passive embedded computing systems.
