Title: Human-Computer Interaction, Sensing and Communication with Battery-Free Systems
Presenter: Przemysław Pawełczak, Delft University of Technology, The Netherlands

Abstract: Batteries are one of the primary pollutants of the world, although they are essential to power the world of mobile electronics, including mobile phones and electronic gadgets. But in a world full of ambient energy from sun, heat, and electromagnetic radiation we can power our electronic devices directly from the ambient energy, ditching the batteries. But this comes at a cost. Ambient energy is unstable/unpredictable and special care must be taken to design a battery-free device to be protected from frequent power interrupts caused by these unstable energy sources. I will discuss recent advances in such systems, focusing on human-computer Interaction (battery-free gaming console), sensing (battery-free sensor network) and communication (battery-free intermittently powered Bluetooth) and discuss ongoing research projects pushing the field of battery-free systems forward (including in-body sensing). In this talk I will also cover general views on the state of mobile systems research worldwide and share my experience with managing the lab that focuses on hardware-oriented experimental-driven research: an important research avenue in modern computer science.

Biography: Przemysław Pawełczak is an Associate Professor at Delft University of Technology, The Netherlands leading Sustainable Systems Lab ( He completed his PhD at the same university in Cognitive Radio in 2009 and obtained his MSc degree from Wrocław University of Science and Technology, Poland, in 2004. His current research focuses on low power embedded wireless systems, and batteryless systems in particular, teaching MSc-level courses on wireless Internet of Things and wireless systems. He is the recipient of Dutch Science Foundation Veni grant and was involved in many European research projects including Flagship Quantum Internet Alliance.
