Determination of chemical species is conventionally performed using specifically designed sensor systems. Known sensors operate as point or distributed sensors to measure parameters in a small spatial location or over a large area. Radio frequency identification (RFID) tags have been used for asset tracking. In this work, we apply conventional passive RFID tags (which are 5-10 c each) to chemical sensing. An enormous advantage of our approach is in the ubiquitous nature of RFID tags already deployed in a variety of environments. In our experiments, we chemically modified conventional passive RFID tags and applied them for detection of simulants of chemical warfare agents (CWAs) and toxic industrial chemicals (TICs).
