Tagging Turns into Sensors

Intriguing, seems the RFID tag needs a redesign.  Reminds me of our long look at tags for product identification in many contexts.    Can their use be broadened in useful ways?

Smart Hacks to Turn Tagging Devices into Internet-of-Things Sensors 

University of Waterloo News

Researchers at the University of Waterloo in Canada have developed a method to hack radio-frequency identification (RFID) tags to turn them into Internet-of-Things (IoT) sensors. The team first removed the plastic cover from the RFID tag, then cut out a small section of the tag's antenna with scissors and attached a sensor across the cut bits of the antenna to complete the circuit. This process gave the RFID tag the ability to sense its environment. The researchers equipped another RFID tag with a phototransistor, a tiny sensor that responds to different levels of light. The team also developed an algorithm on the reader side that monitors changes in the tag's signal. Said Waterloo's Omid Abari, "Our main contribution is showing how simple it is to hack an RFID tag to create an [IoT] device."  .... "
