Congratulations to Cheng Qi for his paper, “Low-power and Compact Microwave RFID Reader for Sensing Applications in Space”, which has been awarded the best student paper at the IEEE RFID-TA 2018 conference in Macau, SER China. This work documents Cheng’s work on the RFsat mission with Northwest Nazarene University, which is taking a custom-built GTPG microwave backscatter reader and energy-harvesting tag into space as part of a novel science package. His co-authors are Prof. Josh Griffin (GTPG alum) and Prof. Durgin. Well done, Cheng!

In this lecture from the Wireless Without Batteries series, we discuss a hypothetical device that converts RF energy to heat, and then to DC power. Not only does this nanoscale device outperform conventional Silicon CMOS diode rectification at the nanoscale, but the analysis illustrates the fundamental thermodynamic limits of RF energy-harvesting.
