Wireless sensing and RFID is an interdisciplinary field ecompassing antenna design, radio-frequency design, and sensor materials science, as well as protocol/algorithm development and coding strategies. Many of these elements are interdependent, and thus low-cost RFID and wireless sensors are by definition cross-layer designs. Early work on wireless sensing and RFID at the Media Lab took place in the mid-1990's beginning with the research consortium called Things That Think For more information on this technology, you can request from MIT a copy of my Master's or PhD thesis devoted to low-cost electromagnetic tagging. Click here to see a short online overview of chipless tag technology I wrote in 1999; although somewhat outdated, it still contains a useful survey of RFID and chipless technologies.
In March 2000, Fletcher founded a boutique RFID design company called TagSense, Inc. which designs and manufactures next-generation RFID systems for various clients.
