Based on work as part of the Children’s Hospital of Atlanta (CHoA) pediatric seed grants competition, a team of researchers put together this report in 2013 on the design of a battery-free moisture sensor for diapers and bed-wetting. The final design showed that diversity antennas feeding two RFID chips and a common moisture sensor could be placed on a low-cost, flexible inset and interrogated accurately in a room with a UHF RFID reader.

IEEE RFID 2019 in Phoenix, AZ is coming up soon, with the program at a glance now available. This premier annual international research conference on RFID will be the 13th edition in the series. As a side note, a number of GTPG alums and senior PhD students have positions on the organizing committee this year:
Cheng Qi + Mohammad Alhassoun, poster chairs
Dr. Francesco Amato, publicity chair
Dr. Brian Degnan, TPC – Protocols and Securities track chair
This article provides a derivation of the Rayleigh criterion for surface roughness. As a once-flat surface roughens, the specular reflected wave begins to degrade in power as some of it is scattered in different directions. The result is a … [Continue reading]
Tianchong "Michael" Jiang's MS thesis entitled "Tri-band Object-Resistant Antenna Design", is now available on SmartTech. From the thesis: A new tri-band monopole antenna is proposed in this thesis. The antenna is made up of two simple L-shaped … [Continue reading]
