We recently published a paper on our work:

I work at the UW Sensor Systems Lab on WISP. You can learn more about the lab here.
The Wireless Identification and Sensing Platform (WISP) is an extension of standard RFID. RFID systems typically have two devices, a tag and a reader. When a tag is brought close enough to a reader, the tag wirelessly collects energy from the reader and can send back information. However, typically, tags are pretty limited in what they send. It’s usually only a unique identifier.
WISP devices are tags that can do more than standard RFID, performing computation and taking sensor readings on-board. Tags have been made with temperature sensors, accelerometers and even cameras. The data they capture is sent wirelessly to the reader within close range (up to 5 meters with ideal conditions).
I’ve been working on developing the next generation of WISP (version 6.0) which brings a modular RF board and microcontroller with add-on boards for various sensor types. Additionally, this next generation comes with greater support for usable readers.
