Aaron Parks & Joshua Smith Win Best Paper Award at the 2014 IEEE RFID Conference

Sensor Systems Lab and EE graduate student Aaron Parks and CSE and EE faculty member Joshua Smith have received the Best Paper Award at the 2014 IEEE RFID Conference for their paper, "Sifting Through the Airwaves: Efficient and Scalable Multiband RF Harvesting." Previous Ambient RF harvesting systems worked for only one pre-selected frequency. The new multi-band harvester can capture power from any subset of a group of pre-selected frequencies. Previous systems would be unlikely to work when moved from one city to another; the new technique enhances mobility. In addition, it allows more power to be captured, since the new harvester can capture power from multiple sources simultaneously.

Previous RF harvesters could only capture energy from one pre-selected frequency, limiting mobility, and total power available (top figure). The harvesting technique presented in the paper allows power from multiple frequency bands to be captured simultaneously.
