Perennial and Personalized Sensing through Wireless Energy Transfer and Intra-body Networks

Abstract: As healthcare becomes personalized, we envision an environment where sensors may continuously report physiological data from both on- and intra-body locations. How to power such sensors without battery replacement and developing low-energy, safe communication methods pose a challenge. This talk describes recent advances in designing systems and protocols for wireless charging using using RF waves for the external sensors, and the use of weak electrical currents for data transfer from implants. It explores the fundamental tradeoffs that exist between achieving high data and recharging rates, constructive mixing of radiated signals, and the promise of simultaneous transfer of data over energy. On the implant side, advances in channel modeling and topology placement strategies are discussed with experimental results on low-overhead data transfers from an embedded implant to an on-skin relay node.

Biography: Prof. Kaushik R. Chowdhury received the MS degree in computer science from the University of Cincinnati, Cincinnati, OH, in 2006, and the PhD degree from the Georgia Institute of Technology, Atlanta, in 2009. He is currently Associate Professor in the Electrical and Computer Engineering Department at Northeastern University, Boston, MA. His research interests lie in dynamic spectrum access networks, energy harvesting, and intra-body communication.
