In 2013, the GTPG partnered with the Children’s Hospital of Atlanta’s Pediatric Innovation Seed Grant program to develop what colloquially became known as “wireless diapers”. The thin, low-cost, flexible inset could be placed inside of a diaper or a garment and read by a standard 915 MHz RFID reader. With two diversity antennas and a capacitive moisture sensor, the sensor could reliably power up and measure moisture — even while worn by the user.
In less than 2 months, the IEEE RFID 2019 Conference will kick-off in beautiful San Diego, California. It is the 13 in the conference series and the 12-consecutive event that our group has attended. What started with an invite in 2008 to the Las Vegas conference by then TPC-chair Daniel Deavours has turned into an annual event for our group … and a haven for some of the best multi-disciplinary researchers in the IEEE community. Below is a list of the full-length papers that have been submitted over the years by our group (students bold-faced, as per GT curriculum vitae guidelines). There are 25 total papers to IEEE RFID (and 4 more to the related, international RFID-TA series):
In this paper, the history of RFID energy-harvesting is tracked and compared against the theoretical thermodynamic limits of an RF-to-DC converter. Although RFID harvesting technology has reached a plateau, this is only due to it being “trapped” within the paradigm of Si-CMOS devices. There are tremendous gains to be had by looking at more specialized devices, particularly those that transform energy into non-electrical, intermediate forms. Thermal intermediary (TI) devices, are particularly promising. Browse What RFID Can Teach Us…
Note: This paper was a companion to an invented talk at the IEEE WPTC 2018 conference, which did not appear in the proceedings.
